Abstract
A brushless permanent-magnet motor includes a stator, a rotor rotatably mounted within the stator in a coaxial manner, a magnet set including a plurality of magnet components mounted around the periphery of the rotor and leaving a gap between the magnet set and the stator, and two locating plates made from a magnetically conductive material and respectively mounted at two opposite sides of the rotor for synchronous rotation with the magnet set and the rotor. Thus, the brushless permanent-magnet motor has a high level of structural stability, and can effectively improve the air-gap flux density and electromagnetic torque under the rated revolving speed to further enhance the performance of the motor.
