Angle grinder commutator 8.4*25*16

The commutator fits angle grinder power tool motors.

The angle grinder commutator is widely used in household motors and power tools. The basic structure of the commutator is: including commutator copper pieces evenly distributed on the outer circumference of the commutator body. The commutator bodies are injection-molded together, and the commutator copper sheets are provided with fins which are implanted into the commutator body and firmly combined with the commutator body.

Angle grinder commutator failure and maintenance

The angle grinder uses a series motor, which is characterized by two carbon brushes and a commutator on the rotor. The most commonly burned parts of this type of motor are the commutator and rotor winding ends. If the commutator is burnt, it is generally because the carbon brush pressure is not enough. When the motor is working, if the current continues to be large, the carbon brushes will wear out quickly. After a long time, the carbon brushes will become shorter, the pressure will become smaller, and the contact resistance will be very large. At this time, the surface of the commutator will heat up very seriously.

If there is a ring fire or a large spark on the commutator of the angle grinder, it is necessary to replace the carbon brushes, remove the sundries, make the surface of the commutator smooth or replace the commutator with a new one.
