    The synchronous speed of a motor is determined by the power supply and the number of poles built into the structure of the winding. With a 60 cycle power supply the synchronous speeds available are 3600 RPM, 1800 RPM, 1200 RPM and 900 RPM. Induction motors develop their torque by operating at a speed which is slightly less than synchronous speed.
