Why is a synchronous speed motor considered a constant speed motor?
synchronous motor is a constant speed motor because it will only run at a synchronous speed or not at all.the speed can be changed by changiing the frequency only ns=120f/p
What is the slip of synchronous motor?
A synchronous motor runs at synchronous speed, so there is no slip, or zero slip.
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.
Why is the speed of synchronous motor is more then induction motor?
Synchronous motors run at synchronous speed. An induction motor that has the same number of poles must run at a sub-synchronous speed to create a second magnetic field (a field that is at a different phase angle) to generate torque.
What in slip speed control?
slip speed control refers to induction machines s=(synchronous speed-motor speed)/synchronous speed by varying slip the machine can be either be operate in generated mode or motor mode
What two factors determine synchronous speed?
Synchronous speed is determined by the number of poles on the motor and the frequency of the power supply. Mathematically, synchronous speed (in RPM) can be calculated as 120 times the frequency of the power supply divided by the number of poles.

What is a synchronous motor?
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
Which motor rotate above synchronous speed?
An induction motor rotating at higher than synchronous speed would be generating power, thus would be a generator. No motor operating as a motor runs above synchronous speed.

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.
If a three phase induction motor runs at a speed greater than synchronous speed?
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
Why is the speed of synchronous motor is more then induction motor?
Synchronous motors run at synchronous speed. An induction motor that has the same number of poles must run at a sub-synchronous speed to create a second magnetic field (a field that is at a different phase angle) to generate torque.
Why the DC motor is call as synchronous motor?
A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.
Speed of the stator field of an Induction motor is?
synchronous speed
Why synchronous motor is used in ac and dc?
A synchronous motor is used only with a.c. Its speed is dependent on the frequency of the a.c.
