Three-Phase Induction Motors : Starting, Running & Max Torque Three-phase induction motors are robust, self-starting AC machines widely used in industrial applications due to their simple design and high efficiency. Starting Torque: At startup, these motors draw a large current, producing a moderate starting torque to overcome inertia and initial load. This torque is typically lower than the maximum running torque. Running Torque: As the motor accelerates, the slip (difference between synchronous and rotor speed) decreases, and the running torque develops, reaching its peak near synchronous speed. This is the normal operating region. Maximum Torque (Pull-out Torque): This is the highest torque the motor can produce before stalling. It occurs at a specific slip value, often higher than the operating slip, and is significantly greater than the starting torque. Exceeding this torque will cause the motor to stop.
