So here let us discuss the advantages and disadvantages of asynchronous transmission to better understand this topic.
Depending upon the method of magnetization of the rotor, there are basically two types of synchronous motors:
Let us discuss one by one
Hysteresis motors are seld starting motor. This rotor is a smooth cylinder is made up of with the high coercivity magnetically hard cobalt steel. These motors are expensive and It is used where precise constant speed is required. It is generally used as servomotors.
In a permanent magnet synchronous motor, a permanent magnet is used along with steel for rotor design. They have a constant magnetic field in the rotor, so the induction motor winding cannot be used for starting time. It is used as gearless elevator motors.
The rating of DC motor is larger than one HP or one KW. The external direct current source is connected with the rotor of these motors for excitation. This Dc source is connected with the motor by a rectifier circuit for rectification of supply.
The direct current at the rotor can is provided in two ways first one is by connecting ab external source and the second is by attaching a direct current generator with the shaft of the rotor.
As an electrical, the electrical motor is an electro-mechanical device that converts electrical energy into mechanical energy.
The definition of the synchronous motor states that, An AC motor in which at steady state, rotation of the shaft is in sync with the frequency of the applied current. The synchronous motor works as an AC motor but here the total number of rotation made by the shaft is equal to the interference multiple of the frequency of the applied current.
