Abstract
A motor housing includes a core and a shell having an annular body. The annular body is configured to secure a stator of a motor therein. The annular body includes first and second ends defining first and second openings, respectively. The annular body defines a slot extending along a length of the annular body. The slot is coterminous with the first opening. The core is configured to be in registration with the shell. The core is configured to rotatably support a rotating assembly of the motor including an output shaft. The core includes a base portion, an annular ring, and a guide arm interconnecting the base portion and the annular ring. The core is in registration with the shell when the guide arm is received in the slot of the annular body of the shell to form an interlocking structure.
