Abstract
A method of assembling an electric motor by building the motor in one direction without the need to turn the motor end over end during the assembly process. The method includes providing a first housing section having motor control components preinstalled therein, and a shaft opening therein for the motor shaft; inserting the stator in the first housing section; temporarily inserting a jig into the stator to position the stator in the first housing section, and injecting a settable material between the stator and the first housing section to secure the stator within the first housing section. After the stator is secured, the jig is removed, and a rotor positioned in the stator, a fan is installed on the rotor, and a second housing section is interfit with the first housing section and the first and second housing sections are secured together.
