| Abstract: | In consideration of low power density of electric excitation claw-pole synchronous machine(EECSM) and some difficulties in magnetic field regulation of permanent magnet claw-pole synchronous machine(PMCSM),a new type of hybrid excitation claw-pole synchronous machine(HECSM) was studied.According to electrical machine theory,the calculation method for magnetic circuit and 3D finite element method were used for simulative calculation of the machine,and its noload characteristics and regulation behavior of the machine were discussed.The comparison of the performance of HECSM with those of EECSM and PMCSM shows that HECSM realizes two-direction control of excitation current and makes the output voltage adjustable,and that the output voltage is kept constant in a wide load range. |
