The study of structure and characteristic of a new type HECPSG

Anew type of hybrid excitation claw-pole synchronous generators(HECPSG) was made to solve the power density lowness of the electric excitation claw-pole machine and the difficulty of magnetic field regulation of permanent magnet(PM) claw-pole machine. According to electrical machine principle, a emulated calculation was made on this new type machine in the way of magnet circuit and three dimension finite element method (FEM), the theis also discussing its non-load and regulation characteristic and makes a comparison on the property among this new type electric machine and traditional claw-pole synchronous generator, permanent magnet claw-pole machine.
