Electric Motor Assembly Guide

The use of Electric motors is in abundance today, these devices are everywhere; even your computer has electric motors to power its cooling fans and hard disks. Building a simple Electric Motor is a great way to learn how they work.

Method of making an electric motor includes steps such as:

Mounting a rotor core on a shaft; mounting a pair of thrust collars on either side of the rotor core; mounting a pair of springs on either side of the rotor core; mounting a pair of thrust plates on either side of the rotor core so that each of the thrust plates is coupled to a different one of the thrust collars and each of the springs is disposed between a different one of the thrust collars and the thrust plates to form a first bearing sub-assembly and a second bearing sub-assembly; mounting a first end of the shaft into a bearing portion of a first end shield; positioning a motor frame/stator sub-assembly over the rotor subassembly; and mounting a second end of the shaft into a bearing portion of a second end shield. Securing the first and second end shields to the motor frame.  Positioning the first end shield adjacent one of the thrust plates; and positioning the second end shield adjacent the other thrust plate.
