What Defines the Speed of a Three-Phase Motor? - Wiki ...

Induction motors, which generate the rotor field by induction as implied by their name, have speed values such as 1180 RPM, 1750 RPM and 3550 RPM (slightly below the standard speeds for synchronous motors). Motor speed is defined by two main factors: The configuration of the motor's winding. The electric supply frequency, typically 50 Hz or 60 Hz.

Electrical Induction Motors - Synchronous Speed

The synchronous speed for an electric induction motor is determined by. the power supply frequency, and; the number of poles in the motor winding. The synchronous speed can be calculated as: n = f (2 / p) 60 (1) where. n = shaft rotation speed (rev/min, rpm) f = frequency of electrical power supply (Hz, cycles/sec, 1/s) p = number of poles
