The speed of 50 Hertz 2 poles synchronous generator is 3000 rpm. AC power frequency is determined by the pole number of the generator p and speed n, Hz = p * n /120. The grid standard frequency is 50 Hz, which is a constant value. For a 2-pole motor, the speed n = 50 * 120 / 2 = 3000rpm; for a 4-pole motor, the speed n = 50 * 120 / 4 = 1500rpm. The next most complex motor has two sets of three phase windings, and is called a "4-pole motor". It is the most common motor produced, and has a 60 Hertz base speed of 1800 rpm (the 50 Hertz speed is 1500 rpm). 6-pole motors operate at 1200 rpm (1000 rpm at 50 Hertz). 8-pole motors operate at 900 rpm (750 rpm at 50 Hertz). Rotational speed: 1,350, 1,380, 1,400, 1,420 rpm.

It is usually given in RPM (Revolutions per minute) on an electric motor nameplate. The rated speed is the speed of the rotor. Slip The speed of the rotor magnetic field in an induction motor lags slightly behind the synchronous speed of the changing stator magnetic field. The motor speed calculator calculates the synchronous motor speed from the following parameters: f -Supply frequency (Hz). For example, 50 Hz or 60 Hz. p -Number of poles. For example, 2 or 4. This can be found on the nameplate of the motor.. The motor speed in rpm is calculated as \(n_{s} =2 \cdot 60\cdot \dfrac{f}{p}\) RPM (revolutions per minute) is the nominal speed at which a motor operates under rated load. Motor performance can vary, and slight differences in the actual speed rating is acceptable for most applications. 50Hz motor will run 20% faster on 60Hz power supply AC motor kilowatt is proportional to Torque times RPM. As the motor's torque is not going to change significantly with the increase of frequency, it will now output 20% more power. A 10kW 50Hz motor will be a 12kW motor on 60Hz power source.
