- Bar to shaft high voltage test：between shaft hole and commutator segment ＞150MΩ(Room temperature) 140℃ within 1 h, between shaft hole and commutator segment ＞100MΩ(Heating)
- I.D. Precision of commutator：H7(With bush) H8(Without bush)
- Insulation of commutator segment：≤1/3 nominal insulating thickness Between the segments of commutator
- AC frequency：50HZ 60HZ
- Copper material：sliver copper or electrolytic copper or customized
- Commutator type：hook type, riser type,shell type or planar type
- Dimension：from OD 4mm to OD 150mm. We also provide customized commutator.
We can manufacture hundreds types of commutator with advanced technology, stable performance and high quality according customers' requirements. We also customize commutator as per customer’s requirement.
Note: The voltage with standing tests data between the shaft and the segment of commutator and between the segments depend in the different users of the motor to complete and the users’ requirement.
Negotiation may be taken if users have other special requirements to the above data in the table.
1. Sliver copper with high intension and wear resistance
2. Long duration time
3. Wide range of commutator
4. Wide application of commutator
5. Good quality
6. Produce commutator as per customer’s drawing.
