摘要： A brushless motor as an example of the invention has a stationary assembly 2 having a first housing member 10 made of a ferromagnetic material and a stator 20 held in the first housing member 10, and a rotor 6 having a rotor magnet 70 facing the stator 20. A annular shield plate 80 held by the rotor 6 is disposed between the rotor magnet 70 and the first housing member 10 and, further, an outer circumferential face 80a of the shield plate 80 is disposed between a magnetically neutral area 46 in the radial direction in the lower end of the rotor magnet 70 and the outer circumferential face of the rotor magnet 70.

摘要： A commutator for a motor and a method of making the same wherein the motor has a stator and a rotor with a rotary shaft and the commutator consists of a plurality of commutator segments embedded in an insulating body, with each of the commutator segments having contact surfaces for engagement with a brush. The commutator is formed with a number of hemispherical shaped impressions so as to form a rough surface.A method of manufacturing the commutator comprises embedding a plurality of commutator segments in a body made of insulating material and the step of forming hemispherical impressions in the commutator segments by directing a jet of particles onto the surfaces of the commutator segments with a predetermined pressure so as to provide the desired roughened surface.
