Product Profile of Asynchronous Three Phase Motors

Rotomotive Powerdrives India Ltd. Offers Asynchronous Three Phase Motors. The Asynchronous Three Phase Motors falls in the Delphi Series. The asynchronous three-phase Delphi series motors are closed, and externally ventilated. In the Asynchronous Three Phase Motors, the frame, up to 132 included is made in die casting aluminum alloy, from 160 the frame is made in cast iron. The specifications of Asynchronous Three Phase Motors:

• Multiple voltage 230V/400V or 400/690V

• And multi-frequency 50/60Hz

• F class insulation

• S1 continuous duty service

• IP55 protection

• 1 or 2 class efficiency
The salient features of Asynchronous Three Phase Motors:

• The copper is impregnated with a double layer of H class insulating enamel to ensure high resistance to electrical, thermal and mechanical stress.

• The phases are further isolated by another layer of Nomex film to protect the motors from the voltage peaks that usually occur when the motor is controlled by an inverter.

• Blocking the bearings into their slots with snap rings prevents them from moving axially. From type 90, a steel insert is provided in the bearing slot of the aluminum flanges, to resist to radial mechanical forces with a fair degree of security.

• The lamination sheets in the Asynchronous Three Phase Motors provide higher efficiency, lower heating, energy saving and longer life to isolation materials

• Feet and connection box can be moved to the right or left
