Design And Research Of Arc Motor For Wing Gate Machine

Permanent magnet synchronous arc motor（PMSAM）is a new type of motor capable of reciprocating arc motion.Applying the direct drive method to the wing gate machine system can not only simplify the system structure to a large extent,but also highlight the advantages of low loss and fast response of the system.However,the magnetic reluctance torque of PMSAM will increase the torque fluctuation of the motor,and then affect the operation performance of the wing gate machine system.Therefore,in order to improve the performance of the motor,this thesis mainly designs and optimizes the PMSAM from multiple perspectives.At the same time,the overall mechanical structure design of the arc motor direct-drive wing gate machine system is carried out.Based on the characteristics of PMSAM,the design process is proposed and the preliminary parameter design scheme of the motor is obtained.The mechanical structure design and assembly method of the new type of PMSAM direct drive wing gate machine system are given,considering the practical application requirements and accidental collision conditions.In order to study the influence of each parameter on the performance of PMSAM,this thesis analyzes the performance of two kinds of arc motor with different number of pole slots,and compares and studies the cogging torque and gap flux density of four kinds of arc coefficient arc motor.The influence of the two primary winding structures on the performance of PMSAM is analyzed.The results show that the interval winding arc motor has higher torque performance than the all winding arc motor,but the armature teeth of the interval winding PMSAM are easily saturated.In order to reduce the end torque of PMSAM,the optimal primary angle of the motor is obtained by combining analytical calculation with finite element analysis.Using the primary unequal tooth structure to solve the armature tooth saturation problem of the interval winding PMSAM,the analytical formula of the cogging torque of the arc motor is derived,and the simulation results show that the unequal tooth structure is effective to improve the electromagnetic torque of the motor.Finally,the transient dynamics analysis of the wing gate machine rotation driven by the optimized PMSAM is carried out,and the simulation results verify the reasonable feasibility of the application of the PMSAM in the wing gate machine system.
