Abstract :
This paper describes a novel contactless auto-generator. The rotor magnet poles of the contactless auto-generator adopt Nd-Fe-B permanent magnet to replace traditional electrical excitation winding and claw-pole. Without electrical brush and slip ring, the structure of contactless auto-generator can be much simpler, the life span can be improved, and the average efficiency can be increased by 20%. The test results of the prototype indicate that this method is completely feasible
