Design Of Stator Bipolar Transverse Flux Motor Based On Permanent Magnet Material

The motor has been widely used as an actuator in the chemical industry,transportation,household appliances and other fields.In the process of use,people always hope that it has high efficiency and power density,so in recent years,different topological structures of the motor are constantly emerging.Among them,the transverse flux type permanent magnet motor has the characteristic of complete decoupling between the circuit and magnetic circuit,which can obtain high power density and torque density,so it has been a broad concern by researchers.Most transversal flux motors present unipolarity,and the permanent magnet materials are not fully utilized.Therefore,flux switching is introduced into the transversal flux motors.A new permanent stator magnet pole magnetic bipolar transversal flux motors with a new structure are constructed and studied.The stator bipolar transversal flux permanent magnet motor can effectively decouple the magnetic circuit from the circuit to play an outstanding role in the lowspeed and high-torque industrial and chemical fields.Moreover,each phase is independent of the other.After the failure of one degree,the different stages can work independently and have considerable fault tolerance ability.The structure of the stator bipolar transverse flux motor is more diversified,and the design freedom is higher.By delving into the structure and functioning of the stator bipolar transverse flux motor,we can gain a better understanding of its characteristics.Utilizing equivalent magnetic circuit methods,we can construct a magnetic circuit model of the motor,which can be simplified based on its structure and working principle to estimate its primary size.Subsequently,by analyzing and calculating equivalent magnetic circuits and finite element methods,the influence of the motor’s structure on no-load and load,back electromotive force,winding self-inductance and mutual inductance,and other parameters can be studied to create an accurate model for improved motor performance.To evaluate the motor’s performance,the structural parameters must be continually adjusted and optimized,such as the size and shape of the permanent magnet material,the size of the fixed rotor core,and the number of turns of the winding.Lastly,after the motor body has been determined,following the general principles of motor design,the equivalent magnetic network method can be used to analyze the no-load back electromotive force and harmonic content of the stator bipolar transversal flux permanent magnet motor,and finite element simulation software can be used to verify if the proposed topology is feasible and reasonable.
