How To Repair Electric Motor Commutator

The flipping the electric field part of an electric motor is accomplished by two parts.

How to repair electric motor commutator.

Capacitor start electric motors use a starting coil and a capacitor to create an advancing magnetic field in the stator outer frame of the motor with its coils. The commutator and the brushes. We work with v bounded commutators glass banded commutators and external internal shrink ring commutators. Electric materials has the capabilities to replace mica v rings or obvious electrical problems within a commutator all in house.

Conduct commutator bar check by setting the voltmeter to the rx 1 scale and then touching the probes of the meter to adjacent bars on the commutator gradually moving around the entire perimeter of commutator. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine. Commutator and brushes the diagram at the right shows how the commutator and brushes work together to let current flow to the electromagnet and also to flip the direction that the electrons are flowing at just the right moment. Two or more electrical contacts called brushes made of a soft conductive material.

The readings should be the same on all bar to bar checks. Electric motor test repair guide. This advancing magnetic field gives the rotor something to chase causing the rotor to spin. Here we provide an electric motor diagnostic table a troubleshooting guide that helps diagnose and repair most electric motor problems for motors found on hvac equipment in buildings such as air conditioners furnace or air handler blower fans oil burner motors well pumps and condensate return.
