Inverter Duty Motor

Amit Electricals manufactures supplier and exporter of Inverter Duty motor. Inverter duty specially winding designed for operations requiring wide speed variation through variable Frequency drives. These motors are generally used when the motor is running for longer duration at speeds below 70% of rated name plate speed.

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