How to repair electric motor commutator.

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. 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. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine. Electric motor test repair guide.

This article describes a c electrical motor troubleshooting. Small electric motor repair by josh weber updated july 21 2017. Electric materials has the capabilities to replace mica v rings or obvious electrical problems within a commutator all in house. This advancing magnetic field gives the rotor something to chase causing the rotor to spin.

The flipping the electric field part of an electric motor is accomplished by two parts. 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. A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. Two or more electrical contacts called brushes made of a soft conductive material.
