These depend on the motor's number of poles. The table shows the Model sizes and specifications for other pole numbers upon request. print site imprint. The speed a synchronous motor will run can be determined by the number of poles of the motor and the frequency of the electrical service using the formula: RPM = Hz* (2 / poles) * 60. where. RPM = shaft rotation speed or revolutions per minute. Hz = frequency or cycles/sec. Poles = number of poles of your motor. Number of poles (AC induction motor) calculator - step by step calculation, formula & solved example problem to find the number of poles required to attain a certain synchronous speed. Line frequency & synchronous speed are the key elements in this calculation. For a four pole machine, 60 x 50 / 2 = 1500 rpm so the same size motor at 5.5kW, 400v but 4 poles will have a nominal speed of 1500rpm but will run near 1455 rpm. When selecting a three phase motor, the number of poles is chosen to achieve the speed of rotation that you require.
A single phase induction motor is an electric motor that operates on a single waveform of alternating current. Single-phase induction motors are used in residential applications for AC motor appliances in single, or multiple dwellings. There are three types of single phase induction motors which are the shaded pole, split phased, and capacitor

When selecting a three phase motor, the number of poles is chosen to achieve the speed of rotation that you require. The number of poles is the total count of magnetic poles placed in a stator to produce a rotating magnetic field. The required speed can be achieved by adjusting number of magnetic poles of stator of an AC synchronous motor.
