Original delphi series asynchronous electric motor.

TECHNICAL CHARACTERISTICS:
4 poles asynchronous speed 1500 RPM, 11 kW, 15 HP, In - 22.78 A, Is - 141.01 A, Cs - 169, Cn - 71.95, Cmax - 212.30, efficiency - 88.9 %, m - 57 kg, deltaT - 80 C dgr.

Motive asynchronous three-phase Delphi series motors are closed, and externally ventilated. The frame, up to 132 included, is made in die casting aluminium alloy, from size 160 up to 355 the frame is made in cast iron.

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.
