Organizing and summarizing search results for youInduction motors have high starting current and starting torque. The motor starts with a rated voltage across its terminals, and the high resistance in the rotor decreases the starting current but increases the starting torque. As the motor picks up speed, the resistances gradually disconnect from the circuit. At the time of starting, an induction motor draws high values of current that are very close to the motor’s locked rotor value and remains at this value for the time required to start the motor. The drive would typically start an induction motor by starting at low voltage and low frequency and increasing the voltage and frequency to the desired operating point.3 Sources
