  • PERMANENT MAGNET MOTOR
    Publication number: 20110241467
    Abstract: A permanent magnet motor is provided. The permanent magnet motor includes: a stator including a stator core, and an insulator for insulating the stator core from the wire; and a rotor in which a rotating shaft is attached to a center of the rotor and a permanent magnet is provided in an outer peripheral portion of the rotor. The stator core includes an annular yoke portion, a plurality of teeth extended radially from an inner periphery of the yoke portion, and a plurality of slots for accommodating a wire to be wound around the teeth at both ends in a circumferential direction of the teeth. A number of the slots in the stator core is set to be 18, the permanent magnet of the rotor is formed by a ferrite magnet, and a number of poles of the permanent magnet is set to be 12.

  • Electrical motor
    Patent number: 7986064
    Abstract: There is provided an electrical motor in which the dimensional accuracy of a stator is increased more easily, and the influence exerted on a magnetic circuit is kept as little as possible. In an electrical motor in which the stator 3 formed with n number (n is a positive integer) of teeth 33 in a row in a straight line form is bent into an annular shape and the end parts thereof are connected to each other, the sum of opening angles ? of a cutout 35 formed between segments of the stator 3 is made larger than 360 degrees, and a minute clearance is formed between the opposed surfaces of the cutout 35 when the stator is bent into an annular shape.
