WebJun 17, 2016 · The difference allows the stator to induce current in the rotor. The difference is very small when the motor has no external mechanical load. For the most common 3-phase motor designs, the slip is about 2 or 3 percent at full-load torque. For single-phase motors, the full-load slip is a little higher. Power is speed multiplied by torque. WebThree-phase induction motors can have a lot of different design configurations. Only the most popular configurations are catalog or stock items. Many special configurations are …
