新型直爪混合励磁爪极电机设计与研究.

Aiming at the problems of easy magnetic saturation, excessive excitation loss and deformation at high speed in the current stage, the excitation mode, magnetic circuit and running stress of the claw-pole motor were analyzed. The permanent magnet and the iron ring gear were added to the root of the claw pole motor to realize the hybrid excitation. At the same time, the claw claw pole motor claw structure was changed to the new straight claw claw pole motor with straight claw structure, and the new motor and the tradition were realized by Ansoft software and Solidworks software. The performance comparison of the motor was analyzed. At the same time, the stress of the motor at different speeds was simulated and analyzed. The results indicate that the new claw pole motor forms a more efficient flux path on the basis of hybrid excitation, and also has higher magnetic saturation current and lower excitation loss, and has better output characteristics. In terms of mechanical properties, the new claw-pole motor has a lower stress effect regardless of the condition, and can fully meet the high-speed operation of the motor. [ABSTRACT FROM AUTHOR]
