Abstract:
An outer-rotor brushless direct-current (BLDC) motor is provided including a rotor shaft, a motor housing having an open end and a closed end that supports a first motor bearing, a stator core having an aperture extending therethrough, a stator mount coupled to the open end and including an elongated cylindrical member projecting into the aperture of the stator core and a radial wall that supports a second motor bearing, an outer rotor, and a rotor mount including an outer rim arranged to couple to the outer rotor and an inner body mounted on the rotor shaft. An intermediate bearing is received at least partially within the aperture of the stator core to radially support the stator core relative to the rotor shaft.
