Construction of universal motor

The construction of a universal motor is very similar to the construction of a DC machine. A stator is mounted on which field poles are attached. Field coils are would on the field poles. Still, the whole magnetic ath is laminated. when operating on AC, lamination is required to minimize eddy current.

Stator

A stator is a part that does not move. It is a stationary part, which contains the following components
  • Field coils
  • Laminated case
  • Wiring from source
  • Brushes
Rotor

The rotor is a rotating part, it consists of the following main part
  • Shaft
  • Commutator
  • Rotor windings
Commutator

Commuters work like a reverse the direction of current in the rotor and external circuit. So we make sure that the current flowing through the rotor winding is always in the same direction.

Brushes

These are the components of the stator that help in the passage of current to the rotor, or moving section, of the universal motor. Brushes are often produced from graphite.

Frame

the frame is built of steel or rolled iron shells. It is in charge of keeping the magnetic field and motor body laminations in good condition.

Construction of universal motor

Working of universal motor

A universal motor can be powered by a direct current (DC) or a single-phase alternating current(AC) source. When a DC supply is connected to the universal motor, it operates as a DC series motor. An electromagnetic field is created when electricity travels through the field winding. The same current runs through the armature conductor as well. When a current-carrying conductor is placed in an electromagnetic field, it experiences a mechanical force. As a result of this mechanical force, or torque, the rotor begins to rotate. The direction of this force is determined by the burning left-hand rule.

When creates unidirectional torque powered by an alternating current supply. Because the armature and field windings are linked in series, they are in the same phase. As a result as the polarity of AC changes regularly, the reaction of current in the armature and field winding reverses at the same time.
As a result the direction of the magnetic field and the direction of armature current reverse, while the direction of force experienced by armature conductors stays constant. Thus, regardless of whether the power source in AC or DC universal motors operates on the same principles as DC series motors.

What is FPGA? Definition | Market Development

Introduction

The Field Programmable Gate Array, or FPGA, is a device that has been developed further based on programmable devices like PAL, GAL, CPLD, and others. In the realm of ASIC, it is created as a semi-custom circuit that not only addresses the shortcomings of custom circuits but also gets beyond the constraints of the original programmable device gate circuit. Its primary feature is that the user can fully configure and program it through software to carry out a specific task. It is currently the primary hardware platform used in digital system design. It is also erasable multiple times.

To convert hardware design effort into software development work, the modification and upgrade only require updating the computer's program rather than making any additional changes to the PCB circuit board. Costs are decreased, implementation flexibility is increased, and the system design cycle is shortened.

What is a programmable logic device?

Given that FPGA is a type of programmable logic device, let's define a programmable logic device. Fixed logic devices and programmable logic devices are the two types of logic devices. As the name implies, the circuits in fixed logic devices are made to last and serve a single purpose or a combination of purposes. It cannot be altered once the manufacturing process is finished. However, PLDs (Programmable Logic Devices) are conventional finished parts that offer a broad range of logic features, including speed and voltage characteristics. Furthermore, this type of gadget can be modified at any time to perform a wide range of tasks.

PLDs are created as general integrated circuits, and the user programs the device to specify the logic function of the device. The level of general PLD integration is sufficient to satisfy the requirements of general digital system design. Rather than requiring the chip manufacturer to develop and produce a specific integrated circuit chip, a digital system can be "integrated" into a PLD by the designers themselves.

The internal digital circuits of PLDs can be programmed after they are created, unlike standard digital chips, and certain PLD types permit modifications following planning decisions. General digital chips are manufactured with predetermined internal circuitry that cannot be altered. The majority of mixed-signal and analog chips are the same. Once they leave the manufacturer, they are unable to modify or fix their internal circuits.

Memory, microprocessors, and logic devices are the three main categories of devices used in digital electronic systems. Random information, like the contents of a database or datasheet, is kept in memory. Word processors and video games are only two examples of the many activities that a microprocessor may perform by executing software instructions. Device-to-device interface, data transmission, signal processing, data display, timing and control operation, and all other tasks necessary for system functioning are among the specialized services that logic devices offer.

There are two types of logic devices: programmable logic and fixed logic. From the initial concept to the prototype and production, fixed logic should be incorporated. A new design for the gadget should be made after the application has changed. Programmable logic devices offer the benefit of not needing to be completely redesigned if the application changes and the device malfunctions. The logic devices only need to be directly reprogrammed, which saves money and time during the early stages of development.

Design Flow of FPGA

Since FPGA is a programmable chip, there are two components to its design process: software and hardware design. Input and output interface circuits, memory, FPGA chip circuits, and other devices are examples of hardware. The software consists of the matching Verilog HDL and VHDL programs. FPGAs use a top-down approach to design, beginning with the system-level architecture and working their way down to secondary and tertiary units until they are confident that the IP core, or fundamental logic unit, can be operated directly. The steps involved in the design process are generally as follows:

Definition of function and choice of device

The system function and module division must be defined before the start of the FPGA design project. Furthermore, the task requirements, including system function and complexity, should be taken into account while balancing work speed, resources, cost, and wire distributability. Next, decide on the best device kind and design strategy.

Design input

Schematic and hardware description language input are two types of design input. Although schematic input is easy to understand, it is difficult to simulate. It is also hard to maintain and inefficient. It is not beneficial for building and reusing modules. Its inadequate portability is its primary drawback. Every schematic needs to be updated when the chip is upgraded. Verilog HDL, VHDL, System C, and other hardware languages are examples. Some common characteristics of hardware description language input are that it is independent of chip technology, allowing for easy module transplanting and partitioning and supporting top-down design. They have robust logic descriptions, simulation functions, and good portability.

Functional simulation

Before compiling, functional simulation, also known as pre-simulation, is used to confirm that the user-designed circuit has a logic function. Only the function's first detection is available at this moment; there is no delay information.

Synthesis

Transforming the description of the higher level abstract level into the lower level description is known as "synthesis." By the logical connections produced by the optimization of goals and specifications for the execution of FPGA layout and wiring software, integrated optimization can create a hierarchical design plane. Currently, synthesis involves assembling the design input into a logical join network table using fundamental logic components such as triggers, AND and disjunction gates, inverters, RAM, and so forth. A true gate circuit does not exist.

Market Development of FPGA

Actually, a number of businesses withheld their products from the PLD (programmable logic device) market or sold their PLD businesses in the late 1990s, resulting in a strongly integrated FPGA market. or establish an independent firm and split off the PLD business.

In the FPGA industry nowadays, there are just a few prominent manufacturers: Altera, Xilinx, Actel, Atmel, Lattice, Quick Logic, and so forth. QuickLogic, however, was also certain to exit the FPGA industry in November 2007.

Nonetheless, there are still emerging producers of FPGA, such Math Star and Achronix Semiconductor. The mix-up and analog programmable logic devices likewise cut a figure, with the exception of programmable logic devices with basic digital logic features. One such adjustable mix circuit is included in the PSoC (Programmable System-on-Chip) from Cypress Semiconductor. For instance, Actel has also suggested the Fusion programmable hybrid chip. It is thought that this could provide programmable processors with higher kinetic energy.

Beyond its initial use in communications, FPGA (Field Programmable Logic Devices) devices are now used in consumer electronics, automotive electronics, and industrial control industries. The way that FPGA products have evolved in recent years has become increasingly clear: on the one hand, suppliers of FPGAs are dedicated to utilizing cutting-edge technology to increase product performance and lower product costs; on the other hand, an increasing number of generic or custom intellectual property rights (IP) have been added to FPGAs in order to satisfy customer demands for quick product launches. Furthermore, FPGA companies are working very hard to lower the power consumption of their products in order to satisfy the industry's growing demand for low power consumption.

Disadvantages of 3 point starter

  • The main drawback of 3 point starter motor is, that it is a huge variation of speed by adjustment of the field rheostat.
  • This starter is not suitable for variable-speed motors.
  • When increasing the high resistance to achieve a high speed, the field current will always be extremely low.
  • Large field current adjustments are not suitable with  3-point starters.
  • The holding electromagnet won't be able to endure the force of the spring if the field current is relatively low.
  • The NVC fails to hold the handle in the ON position, which would disconnect the motor from the supply, at a low field current.
  • This magnet can disconnect the H handle from the power source and release its arm via the usual motor function.
  • When there is no volt trip coil associated in the parallel field, the 4-point stater can therefore be used.
  • The field winding does not have extra resistance in series, so speed regulation isn't possible.
  • The condition circuit may be damaged during a fault because there isn't any extra protective resistance.

Disadvantages of MP4

MOV was first created by Apple as an MPEG4 video container file format for its Quicktime players. In 1998, the company adopted the format for the first time. It functions as a container file for a variety of media data formats, such as subtitles, audio, and video. With this plugin, you may also store interactive multimedia, virtual reality content, and 3D animation. To gain a deeper understanding of this subject, let us examine the drawbacks of MP4.

Disadvantages of MP4 | Drawbacks of MP4

  • Video and Audio can sometimes go out of sync due to codec compatibility problems.
  • MP4 files can contain a variety of multimedia material and metadata, thus playing back and modifying them demands a lot of processing power.
  • Sometimes problems with codecs or codec player compatibility cause the audio to lose sync with the sight.
  • While MKV provides high-resolution video, when audio is recorded at a low bit rate using poor equipment the quality of the audio is usually compromised.
  • MP4 files can be shared illegally and metadata can be removed.
  • Video compressed using MP4 is still lost even though the quality is good. It is not a good option for a video that is really high definition.
  • MP4 files can require a lot of processing power because they contain both audio and visual data.

MKV Full Form

What is the MKV file format?

Matroska video files have the .mkv file extension. Similar to MOV and AVI, it is a container for videos that may have a limitless amount of audio, picture, and subtitle tracks. MKV was selected as the primary video container format for the well-known DivXplus program because it allows descriptions, ratings, cover art, and even chapter points. This format is frequently considered the carrier for high-definition internet video. It is possible to host a movie with several language audio tracks and corresponding subtitles in one MKV file, allowing the user to select the appropriate audio and subtitle format while watching the video. Because of this property, the MKB format can be quite practical.

OT vs IT | Difference Between IT and OT Explained

In simple terms, the main key difference between IT and OT systems is that OT is focused on behaviors and outcomes.  On the other hand,  IT is focused on data communication. So let us check out the difference between OT and IT to better understand this topic.

What is Operational Technology(OT)?

Operational Technology (OT) is an industry or enterprise that can use an OT network to monitor devices, various industrial processes, and industry events and make necessary adjustments. Operational technology also known as OT, is a category of computing systems that process operational data such as telecommunication, technical components, and computers. OT uses a combination of hardware and software to conduct real-time operations and identify any changes that have occurred all through the process. This can be achieved by directly controlling industrial equipment and certain events that occur within the enterprise, which increases the equipment's rate of availability and reliability.

What is Information Technology(IT)?

The term information technology(IT) describes a wide variety of hardware used in networks, including switches and cables, communication devices and protocols, and servers and software for data storage. To store manage, and transfer information typically for business applications, It networks, and IT devices cooperate. MRP and ERP systems are two instances of IT software.  These software programmers operate at a high level, controlling computations, planning, and other high-level operations that are utilized to coordinate industrial processes or make commercial decisions.

OT Vs IT | Difference between IT and OT

  • OT network is industrial oriented but IT network is business oriented.
  • OT network mainly interacts with machines, and IT network mainly deals with information rather than machines.
  • OT network is connected with the outside world whose access is not limited, IT network is limited to people who have certain privileges.
  • OT has different types of data in the network: Monitoring, control, and supervisory data. On the other hand, IT has different types of data in the network, transactional voice, video, and bulky data.
  • OT networks may have risks regarding the information, and IT networks may have automation risks.
  • OT network works on real-time processing of data, and IT network works on transactional processing of data.
  • OT network failure can result in the end of life, but IT network failure can result in loss of data.
  • OT network requires network upgrades only during operational maintenance windows, IT network often requires network upgrades.
  • OT has a less changing environment as the requirements are not frequently changing, and If has a frequently changing environment.
  • The IT network verifies security by authenticating users and devices on the network, whereas the OT network manages physical access to any device.
  • If there is any disturbance in the OT network, It will directly impact the overall business. However the IT network failure can be business impacting, and it depends on the industry.
