The ____ speed of an electric induction motor is the speed at which the magnetic field rotates around the stator.

A) synchronous
B) asynchronous
C) split-phase
D) distributed

The synchronous speed of an electric induction motor is the speed at which the magnetic field rotates around the stator. It is determined by the number of poles the stator winding has and the frequency of the AC power supply. In contrast, asynchronous (or slip) speed is the actual speed of the motor's rotor, which is always slightly slower than the synchronous speed due to slip. Split-phase and distributed refer to types of electric motors and do not directly relate to speed.
