### Electric Motors Torque vs. Power and rpm

Electrical Motor Power, Velocity and Torque Equations. Torque in Imperial units can be calculated as. T inlb = P hp 63025 / n (1). where . T inlb = torque (in lb f). P hp = horsepower delivered by the electric motor (hp). n = revolution per minute (rpm) Alternatively . T ftlb = P hp 5252 / n (1b). where. T ftlb = torque (lb f ft). 1 ft lb f = 1.356 Nm

### How to determine the pole number of an induction motor

15/11/2014· 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. Here are two tables, one for a 50 Hz power supply and one for a 60 Hz power supply: The formula is n = 60 x
