Web27 apr. 2024 · An induction motor typically runs at a little below synchronous speed. The amount it runs slow is called the 'slip'. For small values of slip, the current it draws is proportional to the slip, and to the voltage. This means the torque, which depends on current, is proportional to slip at constant voltage. WebThis condition is also known as the locked rotor or blocked rotor condition. If the induced rotor voltage at this condition is E 20 then the induced voltage at any slip is given by the equation shown below: The rotor resistance is constant and is independent of the slip.
