Abstract
An electric motor including: a frame; a rotor assembly including a magnet, a bearing assembly, an impeller, and a shaft; and a stator assembly including a stator core and a bobbin. The frame has an inner wall and an outer wall, the outer wall surrounds the inner wall and defines an annular channel between the inner wall and the outer wall, and diffuser vanes extend from the inner wall to the outer wall through the annular channel. The inner wall defines a bore for supporting the rotor assembly, and the outer wall defines a substantially cylindrical outer casing of the motor.
