Slip

This calculator allows to calculate and understand the relationship between motor speed, power, and torque. 

The following formula is used to calculate the Toque, Speed, Slip of a 3-phase electric motor:

Torque (Nm) = 9550 x P / N (rated speed)

Speed (Rpm) = 120×f/P

Slip = (Ns – N) / Ns * 100%
