Havells manufactures squirrel cage inverter duty motors which are specially designed for operations requiring wide speed variation through variable speed drives. These motors are generally used when the motor is running for longer duration at speeds below 70% of rated name plate speed.

Inverter duty motors operate at constant torque upto rated design frequency when connected with variable frequency drives.

The motors are fitted with separate cooling arrangement which ensures that the motors perform successfully at lower speeds without over-heating of the motor. This also ensures that the loading capacity of the motor is not reduced in this range.

All external cooling fans are rated at 3000 rpm which provide excellent cooling to the motors even at lower speed of operation.
