Abstract: A brushless permanent-magnet motor includes a rotor, a magnet set mounted at the rotor, a stator coaxially surrounding the magnet set in a coaxial manner relative to the rotor, and a bushing set between the magnet set and the stator in a coaxial manner relative to the rotor and the stator. The stator has a plurality of teeth spaced around the inner perimeter thereof and a retaining crevice defined between the distal front end portions of each two adjacent teeth remote from the inner perimeter. The bushing has a plurality of locating ribs respectively engaged into the retaining crevices of the stator. Thus, the brushless permanent-magnet motor has a high level of structural stability, and can effectively reduce the air-gap flux density variation and instant cogging torque and torque ripples and solve vibration and noise problems.
