Formula

## AC Induction Motor Speed The speed of an induction motor depends on the supply frequency, number of poles, and load-dependent slip. ### Formulas **N_sync = 120 f / P** (synchronous speed) **N_actual = N_sync (1 - s)** (actual speed) where f is the supply frequency in Hz, P is the number of poles, and s is the slip (as a decimal). Synchronous speed is the rotating magnetic field speed. The rotor always turns slightly slower.

Esempio Risolto

A 4-pole motor on 50 Hz supply with 3% slip at full load.

  1. 01Synchronous speed = 120 x 50 / 4 = 1500 RPM
  2. 02Actual speed = 1500 x (1 - 0.03) = 1455 RPM
