Centrifugal Force vs Centripetal Force

What is centripetal force?

This is the amount of force used to move something in a circle. The force may be anything from friction to gravity to rope tension or some combination of these. The term "centripetal force" refers to a real force that causes something to shift in a circle. This force is often aimed toward the circle of motion's base.

What is Centrifugal force?

This is the force used to make a noninertial reference frame appear to be stationary. This fictitious force appears to drive you away from the middle of the circular motion.

Difference between centrifugal force and centripetal force:

Centrifugal force is an object moving in a circle and experiences an outward force then this force is called the centrifugal force, while the object travels at a uniform speed in a circular path is called centripetal force.
Centrifugal forced flying of a tire is one example of the centrifugal force, while the centripetal force is a satellite orbiting a plant is an example of the centripetal force.
Centrifugal force has object has direction analog the center of the circle from the center approaching the object, while centripetal force object has the direction along the center of the circle from the object approaching the center.

Difference between Contactor and Starter

What is a contactor, exactly?

Contactors are electrically operated switching devices that are used to make electrical connections. The basic operation is similar to that of a relay, with the exception that the contractors can bring a broad current up to 12500A to the relay. They can't defend against short circuits or overloads, but they can break the contract if the coil is excited.

What is a starter?

A starter is a mechanism that rotates an internal combustion engine so that it can start running on its own power. Electronic or hydraulic starters are available.

Difference between contactor and starter:

A contactor is an electrical switch that functions similarly to a relay, whereas a starter is a contactor with an overload relay.
A contractor does not have an overload coupled to it, while a starter has multiple overload options.
In comparison to a starter, which is usually rated by its current capacity and the horsepower of the motor with which it is compatible, a contactor is normally graded by its voltage capacity.
A contactor closes the contacts and supplies and interrupts power to the circuit by applying a voltage to a contactor coil. An overload relay is used by the starter to protect the motor from load surges by shutting it down to avoid overheating.

Difference Between Soft Starter and Star-Delta Starter

What is a Soft starter?

The soft starter is a semiconductor-based motor starter that regulates the voltage supply to the motor with a thyristor. To minimize the inrush current that can harm the motor windings, the voltage is decreased at startup. When the motor reaches its rated speed, the voltage is progressively increased.

What is a star-delta starter?

A star-delta starter is the most commonly used method for the starting of a 3 phase induction motor. When the motor reaches about 80% of its full load speed, it will begin to run in a delta-connected stator winding.

Difference between soft starter and star-delta starter:

Star delta starter only has two states, low voltage, and full voltage, that the starter jumps between, soft starter start-up gradually, they can have infinite states within the limits of the controlling electronics and your startup requirement.
The soft starter can handle varying load conditions, such as loaded and unloaded starts, while the star delta starter can not.
Soft starter allows you to control the starting time, while star-delta starters do not. The starting time for the star delta starter is about three to seven seconds, while the soft starter has an adjustable time of between one and around 60 seconds.
Some soft starter also offers soft stop functionality, while the star delta starter does not.
Star delta starters are more complicated than a soft starter. It is also easier to install a soft starter.
With an extremely light load, Star delta able to reduce the starting current to a lower level than a soft starter could.
Soft starters offer dynamic torque control, which allows you to adjust the torque to accommodate different motor and load characteristics with star delta starter, you can't adjust the starting torque.
Star delta starter, between the star and delta connection, there is an open transition that can result in transients and high torque. During this transition, there is also a power outage. With a soft starter, there is no such open transition and no power loss.
Soft starter cost more than a star-delta starter, although soft starters is more efficient. However, the cost difference between the two types of starter is less than what it once was.
Star delta starter can be used for low power machines starting load, medium power machines without load, low power fans, and low power centrifugal pumps, The soft starter, on the other hand, may be used with large motors with or without load, such as those used in compressors, fans, pumps, conveyors, agitators, mixers, mills, and other applications.
