Download as PDF
The structure of claw-pole permanent magnet generator is introduced in the paper; Major magnetic flux circuit of claw-pole permanent magnet rotor is analyzed. In calculation method of permanent magnet volume and armature winding turns, determination of important parameters is researched. The magnetic circuit model is built by equivalent magnetic circuit method. Permeance and flux are calculated. The performance of the generator was tested, It is proved that the generator has the characteristics of high efficiency and high reliability.
