Verified
The number of poles, combined with the alternating current frequency (HZ) , determines the synchronous speed ____ per minute (RPM) of induction motors.
A) references
B) resolution
C) round
D) revolutions
Synchronous Speed
The speed at which the magnetic field in an AC motor rotates, directly related to the frequency of the power supply and the number of poles in the motor.
Alternating Current Frequency
The number of cycles per second in an alternating current (AC) waveform, typically measured in hertz (Hz).
Revolutions Per Minute
The unit of measure for rotational speed, indicating the number of full rotations completed by an object in one minute.
- Understand the importance of synchronous and asynchronous speeds in induction motors.
- Comprehend the theoretical foundations underlying the functioning of three-phase motors.
