Title:
DC BRUSHLESS MOTOR
Document Type and Number:
Japanese Patent JPS59106868
Kind Code:
A
Abstract:
PURPOSE:To enable to generate the prescribed torque by axially interposing a permanent magnet between stators having a plurality of windings, thereby shortening the axial length. CONSTITUTION:Permanent magnets 50 used as a rotor are formed in a doughnut shape, and composed of sector magnet segments. The magnets 50 are secured to a shaft 52 through a stay 53. A coil 60 holds the magnets 50 toward the shaft 52, and is used as a stator. The coil 60 is secured to a yoke 70, and the prescribed clearance 72 is formed between the magnet 50 and the coil 60. A current flowed to the coil 60 is sequentially switched by a control circuit 40, thereby generating torque at the magnets 50.
