Abstract: A brushless motor includes a stator and a rotor. The stator includes a stator core and a plurality of windings. The stator core includes a yoke, and a plurality of teeth extending from the yoke. Each of the teeth comprising two pole shoes extending in opposite ways along a circumferential direction of the yoke. Pole shoes of adjacent teeth are connected through a magnetic bridge having a larger magnetic reluctance than that of the poles shoes, which reduces the magnetic leakage and increases the motor power density. Axial thickness of each of the magnetic bridges is smaller than that of the poles shoes.

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.
