Title:
CONTROLLER AND SYSTEMS OF PERMANENT MAGNET ALTERNATOR AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2012/008137
Kind Code:
A1
Abstract:
Solenoid coils disposed at a position not interlinked with a magnet flux of a rotor are used to increase the inductance of control coil system for controlling the generated voltage by letting flow small a current amount into a switch which system is no need to increase winding number of power coil. In the generator with a rotor installed permanent magnet pieces and a stator disposed at the outside of the rotor, a winding coil of the stator for power coil 10,11 and a solenoid coil of the power coil side 141 and a solenoid coil of control side 142 which are disposed at a position not interlinked with a magnet flux of a rotor, are connected in series and a power terminal is provided at least between the solenoid coil of power coil side and the solenoid coil of control side and a switch for letting flow a part of a current amount generated in the power coil to the solenoid coil of the control side 142 for controlling current amount flowing into the solenoid coil of the control side 142 by controlling ON/OFF of the switch 13 which is disposed on the DC terminal of the rectifier 143 connected with the solenoid coil 142 in series so that a generated voltage is controlled to a voltage set in advance in response to a detection signal from a sensor 16 for detecting the generated voltage by the power coil is provided then the controlling is carried out by controller 18. On the other hand, neutral switches 391, 392 are used for increasing control range in the generator and motor.
