Abstract

The invention provides a rare earth permanent-magnet DC generator. The rare earth permanent-magnet DC generator comprises a power module, a rare earth permanent-magnet generator, a voltage stabilizingcircuit, a control module and a test module. The invention can solve the problems that the number of components and parts is increased, the weight of a permanent-magnet DC generator is increased, andthe whole machine operation voltage regulation reliability or transient characteristic is poor in an existing DC permanent-magnet generator set voltage regulation mode. Therefore, the direct-currentpermanent magnet generator set is higher in reliability and good in transient characteristic in the voltage regulating process, and has the automatic voltage regulating and stabilizing functions.
