all that is known about the factory rotor circuit is a single-layer winding, pitch 1-6, 48 slots, 2 stars constantly on.
in the attachment it would seem that the circuit is correct, but it only works when the rings are closed (8 poles), when opened, the shaft rotates by hand at the rated voltage...
Hello. Thanks for your quick reply. I am sending you the winding data. The number of turns is 11, the pitch of the slots is 1-6, the diameter of the conductor is 1.4x4 (approximately 6.1 square millimeters). The length of the rotor active steel is 350 mm, the diameter is 280. This data was taken...
Hello. We have a Chinese-made motor with a wound rotor YZRDW250M-8/4 30 kW under repair. The rotor was rewound, the stator has a factory winding. Please help connect the rotor winding. As I understand it, the rotor winding is 8 poles, when operating at 750 rpm, the rings close, and when...
