Title:
SYNCHRONOUS MOTOR
Document Type and Number:
Japanese Patent JP3358666
Kind Code:
B2
Abstract:
PURPOSE: To obtain a synchronous motor having no brush for DC energization, requiring no complicated constitution and being high in starting torque in the same way as induction motor and capable of self-starting.
CONSTITUTION: A stator side 1, in which the thirst main winding 3 and second main winding 4 of a star connection are connected in parallel with a three-phase AC power supply 5 and single-phase exciting windings 6, 7 are provided and further the exciting windings 6, 7 are connected in series via diode 8, and a rotor side 2, in which rotor windings 9, 10 are provided and connected in parallel and diodes 11, 12 are connected between nodes connecting the rotor windings 9, 10 in parallel, are constituted in the this apparatus. Also, switches 13, 14 are provided at either end of respective-phase windings 4R, 45, 4T of the main winding 4 of the stator side 1 in the manner of switching the polarities of the windings so that a phase-shifting device 15 is constituted in the main winding 4.
