Electric Motor Bushings

An electric motor does not have bushings inside it as required operational parts. Some motors will have bushings that connect them to other parts on a vehicle or machine, however, or that maintain the stability of the rotor shaft.

Internally, an electric motor requires only 2 magnets, a stator, and an electrical input for either the stator or both the stator and the magnets. When electricity is applied, the oscillating electrical pulse on the stator causes it to spin as the magnets alternate between attraction and repulsion.

This spin turns the central shaft, which is the ultimate result of the energy conversion from electrical to mechanical. Its this shaft that will most often have bushings to accomplish various tasks.

A bushing may be present between the motor housing and the shaft where it protrudes, acting as a sort of coupler and barrier. This bushing may or may not have bearings or rubber to form a seal and ease the shaft's turn.

Other bushings will be located as mount absorbers to minimize shock to the motor. These bushings will be made of rubber or similar material.

Still others may attach to the end of the shaft to make for a connection to another mechanical item, such as whatever the motor is powering.

These bushings will likely be made of steel or another durable substance and will vary in size and shape according to what they're meant to connect the motor's shaft to. Some may even fit over the shaft to increase its diameter so it will fit inside another component.

The different components of the machine to be operated by the electric motor will determine the type of motor and bushings used.
