Title:
PERMANENT MAGNET ROTOR TYPE SYNCHRONOUS MOTOR
Document Type and Number:
Japanese Patent JPS6026450
Kind Code:
A
Abstract:
PURPOSE:To facilitate the start of rotating by arranging an auxiliary stator by an auxiliary winding and a stator as a pair near a rotor of a permanent magnet in different polarities. CONSTITUTION:A cylindrical permanent magnet rotor 1 and a stator core 3 magnetized in two poles are provided perpendicularly to a rotational shaft, and an armature winding is wound on the core 3 to form a synchronous motor. In this case, auxiliary stators 10a, 10b, on which auxiliary windings 11a, 11b are wound, are disposed near the rotor 1 so as to become different polarity from the stators 3a, 3b. Thus, attracting forces Fe2, Fg2 act between the poles 10a, 10b and the rotor, and repelling forces Fe1, Fg1 act between the ends 3a, 3b of the stator at the points E, G and the rotor 1 is started to rotate by the composite forces Fe, Fg.
