    摘要： A brushless motor has a stator and a rotor. The stator has a stator core with a plurality of inwardly extending salient poles and windings wound about the salient poles. The rotor has a shaft, a rotor core fixed onto the shaft, and magnets inserted in the rotor core for forming magnetic poles of the rotor. Each of the salient poles has a pole shoe with a pole face that extends along a circumferential direction confronting the rotor core and being spaced from the rotor core by an air gap. In a radial cross section of the motor, each of the magnetic poles of the rotor has an effective dimension (W) which is about 0.85 times to 1.2 times of the chord length (L) of each pole face.

    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.

    摘要： An electric motor has a wound stator and a permanent magnet rotor. The rotor includes a shaft, a hub fixed on the shaft, a plurality of rotor core segments and magnets fixed around the hub. The rotor core segment includes at least two rotor blocks inwardly extending from the innermost portion thereof. The hub includes a plurality of hub blocks equidistantly and outwardly extending from the outer surface thereof. The rotor blocks of each rotor core segment engage with at least one hub block to fix the rotor core segment to the hub. The number of rotor blocks is greater than the number of hub blocks.

The first bars and the second bars are fixed to the outer surface of the core and are alternately arranged at equally spaced intervals in the circumferential direction of the core. The first slip ring and the second slip ring are arranged on the same side of the first bars and the second bars. The first and second slip rings respectively comprise a contact surface that is substantially perpendicular to the axis of the commutator and is configured for contacting brushes.
