Rotor testing: precision testing, quality selection

In the rotor production process, the testing process is the key to ensure its excellent performance. The rotor testing machine process mainly includes resistance testing, turn-to-turn testing and high-voltage testing.

Among them, the resistance and turn-to-turn tests work together to check the winding performance. When qualified, the resistance value is accurate, the turn-to-turn insulation is good, and the waveform is normal, ensuring stable current transmission and conversion.

If it is unqualified, the resistance is abnormal, and the motor operation will be seriously affected.

High-voltage testing is a severe challenge to the insulation strength of the rotor. Qualified rotors can calmly cope with high-voltage shocks and have reliable insulation.

Unqualified ones will cause insulation breakdown under high voltage, causing safety hazards.

Through these comprehensive and precise tests, high-quality rotors are accurately screened to lay a solid foundation for the excellent performance of the motor.
