Customized Universal Motor Commutator 

The motor commutators are suitable for permanent magnet (PM) excitation and the universal motor.

Commutator parameters

Technical requirements for commutator

The commutator must be nearly round to prevent brush bounce and excessive arcing. The higher the speed of commutation, the greater the need for more perfect concentricity.

Commutator Application 

Commutators are suitable for universal motors. Widely used in power tool motors , kitchen products motors , floor care products motors , etc.

The universal motor has widespread application in household appliances. It is a commutator machine with series-connected excitation. It is called universal because it can operate with ac as well as dc supplies. The action of the commutator is to convert the slip frequency generated in the armature windings back to supply frequency across the brushes. As the armature rotates, the copper piece comes into contact with the fixed brush. In a DC motor, the alternating current in the armature winding is changed into the direct current between the brushes by means of a brush and a commutator. In the AC commutator motor, the frequency of alternating current between brushes meets the working requirements.

Information needed for commutator inquiry:

1. Commutator dimension: OD, ID, total height, and copper height, bar number.
2. Commutator type: hook type, raiser type or planner
3. Copper material: Agcu/ Cu
4. Commutator applications
5. Required quantity
6. Copper bush needed or not

7. Other technical requirement.
