The RPM speed difference between the stator rotating magnetic field, synchronous speed, and the actual rotating speed of the rotor, is called ____.

A) coil
B) slip
C) load
D) torque

Rotating Magnetic Field

A magnetic field that rotates in space within an electrical machine, such as an induction motor, enabling motion of the rotor.

RPM Speed

A measure of the rotational speed of a mechanical component, denoted in revolutions per minute.

Synchronous Speed

The speed at which the magnetic field in an AC motor rotates, directly proportional to the frequency of the electrical supply and the number of poles in the motor.
