Abstract: A commutator has a conductive layer, a segment layer and an insulating layer separating the conductive layer and the segment layer. The segment layer includes multiple commutator segments. A mounting hole is defined along an axis of the commutator passing through the conductive layer. The three-layer structure of the commutator forms a capacitor having an increased confronting area and reduced inter-plate distance. The capacitor thus has a greater capacitance and hence greater EMI absorbing capability, making it possible to reduce EMI emissions without additional EMI reduction components outside the commutator. A rotor and a motor employing the commutator are also disclosed.

Abstract: A permanent magnet motor has a number of permanent magnets forming permanent magnet poles. Each magnet has an outer surface that is an arc surface with a convex middle. An inner surface of the magnet is a curved surface with a concave middle. The curved surface has an arc surface section and two planar surface sections. The arc surface has a pole arc angle ? of 0.7 to 0.96, and the ratio of an arc angle ? of the arc surface section to the pole arc angle ? is 0.15 to 0.35. The shape of the inner surface of the magnet creates uneven air gaps between the rotor poles and the stator core poles. This reduces cogging torque, increases the motor efficiency, and reduces the motor noise.
