What are Synchronous Motors?Synchronous motor definitionA synchronous motor is an AC motor in which the rotation of the rotor is synchronized with the frequency of the supply current.Constant speed operationSynchronous motors operate at a constant speed called synchronous speed, which is determined by the number of poles of the motor and the frequency of power supply.N= The Synchronous Speed (in RPM – i.e. Rotations Per Minute)f = The Supply Frequency (in Hz)p = The number of PolesThe structure
