What is the name of an electric motor in which rotor and stator fields rotate simultaneously?
The electric motor in which the rotor and stator fields rotate simultaneously is called a "synchronous motor." In synchronous motors, the rotor is designed to rotate in synchrony with the rotating magnetic field produced by the stator. This type of motor is commonly used in applications requiring precise speed control and efficiency.
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 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 a machine should run with synchronous speed?
A synchronous motor is not self starting.However when it is provided with some prime mover ,which rotates it up to 80% of sync. speed,then it continues to rotate at sync.speed even after prime mover is removed.It happens so because rotor poles are locked with rotating magnetic field and hence the speed is always synchronous.
What is the name of electric motor in which both rotor and stator fields rotate with same speed?
only synchronous motor
What is the name of an electric motor in which rotor and stator fields rotate simultaneously?
The electric motor in which the rotor and stator fields rotate simultaneously is called a "synchronous motor." In synchronous motors, the rotor is designed to rotate in synchrony with the rotating magnetic field produced by the stator. This type of motor is commonly used in applications requiring precise speed control and efficiency.
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 slip of synchronous motor?
A synchronous motor runs at synchronous speed, so there is no slip, or zero slip.
What is a synchronous motor?
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
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.
What is the rotor speed of synchronous motor?
It depends on the number of poles and the frequency of the power. A two pole motor running on 60 Hz would rotate at 1800 RPM.
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.
What factors determine the synchronous speed of an AC motor?
Number of poles and supply freqency determines speed of synchronous motor. For speed control of such motors Variable Freqency Drives(VFD) are used.
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.
