摘要： A permanent magnet rotor (1) in which field permanent magnets (10) are installed in slots (9) of a yoke (3) comprising many silicon steel laminations (2) and which is used in a corrosive atmosphere or liquid. The permanent magnets (10) are covered with corrosion-proof plates of corrosion-proof material. Accordingly the permanent magnets (10) are not corroded when in use, and the permanent magnet rotor (1) can be easily manufactured.

摘要： In a rotor (7) of a brushless motor having permanent magnets, a yoke (21) is formed with plural laminated silicon steel plates (22), and, at least four, an even number of magnetic poles are provided on the outer surface of the yoke (21). For these magnetic poles, slots (25), (25) for installing field permanent magnets (30), (31) therein, are provided at equal distances from the center of the rotor every other magnetic pole. In the slots (25), (25), the field permanent magnets (30), (31) are so installed that the like magnetic poles face a rotary shaft (8). Thereby, the rotor (7) of the brushless motor can be reduced in size and has high efficiency, and the field permanent magnets (30), (31) do not break nor fly, even when the motor rotates at a high speed.

摘要： A rotor (31) of a brushless motor comprises a rotary shaft (32) and a main yoke (33) fitted to the rotary shaft (32) in one unit. The main yoke (33) has at least two magnetic pole heads (34a, 34b) radially projecting from the rotary shaft (32). Between the adjacent magnetic pole heads (34a, 34b) there are provided magnet receiving seats (35a, 35b) on which field permanent magnets (36a, 36b) are so mounted that the like magnet poles are directed toward the rotary shaft (32), facing each other. Auxiliary yokes (38a, 38b) are mounted on the outer surfaces of the field permanent magnets (36a, 36b). On the outer surfaces of the magnetic pole heads (34a, 34b) and the auxiliary yokes (38a, 38b), a cylindrical sleeve (40) is provided. Thus the structure of the rotor (31) of a brushless motor is simple, and the magnetic flux ot the field permanent magnets (36a, 36b) are effectively utilized.
