Custom automotive fan motor slot commutator For automobile

Custom automotive fan motor slot commutator For automobile

In automotive fan motors, the slot commutator is a relatively common commutator type.

The manufacture of slot-type commutators for automotive fan motors requires high-precision processing and assembly technology. In addition, the quality and stability of materials must be ensured during the manufacturing process to ensure the reliability and durability of the commutator.

Technical requirement of commutator:

1. Voltage test: bar to bar 500V, bar to bore 1500V, without breakdown and flashing.

2. Spin test: do spin test for the commutator under 140 centigrade, the speed is 5000RPM, the test continues for 3min. After testing, the deviation of outer diameter is less than 0.015, the deviation between bar and bar is less than 0.005.

3. Insulation resistance: 500V, more than 50MΩ
