    Abstract: A motor includes a stator, a rotor rotatable relative to the stator, a support member, and a circuit assembly. The circuit assembly includes a plurality of electronic components. The rotor is rotatably mounted to the support member. The stator is received in the rotor. The stator is fixed to the support member, and the support member is at least partially received in an inner side of the stator. A portion of the support member received in the inner side of the stator defines a receiving space, and at least part of the electronic components of the circuit assembly is received in the receiving space of the support member. The support member is partially received in the inner side of the stator, and the circuit assembly is at least partially received in the support member, which makes the motor have a relatively smaller axial size.

    Abstract: A motor and methods for making and using same. The motor includes a rotor including magnetic poles and a stator comprising a stator core and a winding wound on the stator core. The stator core includes a plurality of stator teeth each including a tooth body and a tooth end formed at an end of the tooth body, the tooth end comprising first and second arcuate regions facing the rotor. When the winding is not energized, a first magnetic coupling between said first arcuate region and a selected magnetic pole of said rotor is greater than a second magnetic coupling between said second arcuate region and the selected magnetic pole, said first arcuate region being offset from a selected tooth body in such a way as to enable movement of said rotor to initiate in either of two opposite directions relative to said selected tooth body upon energizing the winding.

    Abstract: A single phase permanent magnet motor includes a stator. The stator includes a stator core and windings. The stator core includes a ring portion, tooth bodies extending radially from the ring portion, and a pole shoe extending from a distal end to two circumferential sides of each tooth body. Each pole shoe defines a positioning slot. A center of each positioning slot is offset from a center of symmetry of one adjacent tooth body so that a torque fluctuation of an output torque of the single phase permanent magnet motor during operation is less than 50%. As a result, the motor vibration and noise are small.

    Abstract: A blower includes a mounting base, a motor, an impeller, and an electronic control unit. The motor is mounted to the mounting base from one direction. The impeller is mounted on the motor. The electronic control unit is mounted on the mounting base from an opposite direction. The mounting base defines a through hole. The through hole is axially aligned with a motor shaft to expose an axial end of the motor shaft opposite from the impeller. The electronic control unit comprises a printed circuit board disposed offset from the through hole.
