Abstract
The controller of permanent magnet generator controls the current by using control switch which is installed in between power coil and control coil and switches on and off in switches in order to generate two different voltage and increase the power at very low speed condition of generator. The controller controls the voltage of power coil constantly by adjusting current of flowing in the control switch which the voltage is sensed on the load voltage sensor and the controller control the voltage constantly at very small speed by using power switches furthermore, the controller controls the two kind of voltage in power coils constantly by using control switch and switches in case of the generator having different kind of voltages.
Claims16
A controller of a permanent magnet generator, comprising:
- a rotor shaft rotatably supported by a housing;
- a rotor fixed to the rotor shaft, and mounted with a plurality of permanent magnet members on an outer periphery side;
- and
- a stator disposed at the outside of the rotor and wound with a winding coil;
- wherein the winding coil of the stator is formed of a power coil and a control coil connected in series to the power coil and larger in the number of windings than the power coil, and a power terminal is provided at least between the power coil and the control coil, and a switch for letting flow a part of a current generated in the power coil to the control coil and a controller for controlling a current amount flowing into the control coil by controlling ON/OFF of the switch so that a generated voltage is controlled to a voltage set in advance in response to a detection signal from a sensor for detecting the generated voltage by the power coil are provided.
