Abstract

PURPOSE: To obtain an exciting output of small fluctuation and stabilize a run, by providing two groups of stator windings with a pole number ratio of 1:2 on an identical core and providing corresponding rotor windings on another identical core.
CONSTITUTION: A variable-speed synchronous motor 1 is driven by an inverter 6 of variable voltage and frequency and a brushless exciter 11. The brushless exciter comprises stator windings 7 for two poles, other stator windings 8 for four poles and rotor windings 9, 10 corresponding to the stator windings. The rotating magnetic field generated by the stator windings 7 rotates in the opposite direction to that by the other stator windings 8. The field winding 3 of the synchronous motor 1 is excited by the rotor windings 9, 10 through a rectifier 5. As a result, the excitation is less affected by the revolution speed and an excitation output of small fluctuation in a variable speed range is obtained. Therefore, the motor is stably run.
