    摘要: A brushless motor has a stator and a rotor. The stator has a stator core and stator windings. The stator core has a stator yoke and teeth extending radially inwardly from the stator yoke. The stator windings are formed by concentrated coils wound on the teeth. The rotor has a rotor shaft, a rotor core fixed to the rotor shaft and magnets fixed in slots formed in the rotor core. Each magnet is plate shaped and extends in both axial and radial directions of the rotor and each magnet is magnetically charged across its thickness so that a rotor pole is formed between two adjacent magnets. The ratio of the radial thickness (Y) of the stator yoke to the width (T) of the tooth body is from 0.4 to 0.7.
