FLAT TYPE MOTOR
Document Type and Number:
Japanese Patent JPS5683255
Kind Code:
A
Abstract:
PURPOSE:To improve working efficiency for a winding without increasing a magnetic resistance between a rotor and a stator core by providing a pole shoe on the surface of the ring stator core facing to the rotor so that it comes closer to the rotor than ring stator winding. CONSTITUTION:A ring stator core 7 is divided, for example, into a plural pieces, a stator winding 9 which is formed annularly beforehand is fitted in necessary number, and a U-shaped pole shoe 8 is provided on the stator core 7 between the stator windings 9 and opposite to a rotor 3. The pole shoe 8 is constituted to come nearer to the rotor 3 side than the stator winding 9, and the stator core 7, stator winding 9 and pole shoe 8 are covered with a resin layer, which are fixed on a fixed member 11. Then, the stator core 7 and the pole shoe 8 can be formed integrally.
