How you do Speed control of permanent magnet synchronous motor?

To vary the speed of a permanent magnet synchronous motor, you need to vary the frequency of the AC power source. Of course, this also means you need to vary the voltage because the power factor is going to change, and you need to compensate for that or you might damage the motor.


What is the motor parts of the body?

The wires and the permanent magnet


Is the electric motor in a Ford Fusion hybrid AC or Dc?

How is a DC permanent-magnet motor reversed?

Reverse the polarity of armature windings of the motor.


Why 3 phase induction motor is self starting but synchronous motor is not?

the induction motor as soon as you turn on the power the rotating magnetic field is set up. the shorted winding in the squirrel cage see this and builds up a temporary magnet when its up to synchronous speed there is no longer current in the shorted winding in a single pole motor 60hz this speed is 3600 rpm depending on coupling and skew induction motor is always less than synchronous speed. the synchronous motor as soon as you turn on the power the rotating magnetic field is set up the permanent magnet 0 to 3600 rpm in 1/60th of a second this requires all the power you can deliver until you reach synchronous speed a bit hard on the power source smaller synchronous motors sometimes have a squirrel cage and permanent magnets and enough impedance so they dont put a heavy load on the power electric clocks have the shorted windings on the poles self starting hi impedance some older electric clocks didnt have the shorted windings and need to be nudged to get then spinning


How many Slip rings in synchronous motor?

If the synchronous motor is single phase then there are two slip rings & if this motor is three phase so the slip rings are three in number. Correction; I have never seen a single phase synchronous motor. It would cost more that it was worth. A synchronous motor has a separately excited field. If the excitation comes from a stationary DC source it has 2 slip (collector) rings. A brushless induction motor has no slip rings because the exciter armature rotates and so do the rectifiers. A permanent magnet motor, used with variable frequency drives, is another type of synchronous motor that has no slip rings. A three phase motor with 3 slip rings is a Wound Rotor motor. Wound rotor motors are variable speed motors that were used for such applications as bridges and cranes before variable speed drives.


What are the two types of motors?

permanent magnet motors and series motor


What part of an electric motor repels the poles of the permanent magnet?

commutator


Why do you give DC excitation to AC Synchronous motor?

If the synchronous motor is running near synchronous speed, it will begin rotating at synchronous speed when DC is applied to the rotor. Source: Electrical Machines, Drives, and Power Systems Theodore Wildi Section 17.3


What is synchronous machein?

mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
