摘要/Abstract

摘要： 针对新型电机的轻量化、紧凑型、高扭矩密度设计目标，将印制电路板(Printed circuit board，PCB)技术引入定子绕组制造工艺，设计了轴向磁通双PCB定子电机。以单根有效导条为研究对象，建立了电机感应电动势、电磁扭矩及输出功率的解析模型。构建了PCB电机的有限元仿真模型，开展了关键参数优化研究，对串、并联构型双PCB定子电机进行电磁场与温度场仿真分析。基于搭建的试验平台，研究了不同构型下PCB电机的输出性能与温升特性。在额定工况1 500 r/min、3 A条件下，串联双PCB定子电机输出扭矩为130 mN·m，扭矩密度可达2 000 N·m/m³，实测最高温度为180.6 ℃；并联构型下电机输出扭矩为103 mN·m，扭矩密度可达1 584.62 N·m/m³，实测最高温度为110.5 ℃，与同工况下串联构型相比温升更小，可有效改善PCB电机发热问题。

Abstract: In view of the design goals of lightweight, compact and high torque density of new motors, the printed circuit board (PCB) technology was introduced into the stator winding manufacturing process, and an axial flux double PCB stator motor is designed. Taking a single effective conductor bar as the research object, an analytical model of the motor's induced electromotive force, electromagnetic torque and output power was established. A finite element simulation model of the PCB motor was constructed, and key parameter optimization research was carried out. The electromagnetic field and temperature field simulation analysis of the series and parallel double PCB stator motors were carried out. Based on the constructed test platform, the output performance and temperature rise characteristics of the PCB motor under different configurations were studied. Under the rated operating conditions of 1 500 r/min and 3 A, the output torque of the series-connected double PCB stator motor is 130 mN·m, the torque density can reach 2 000 N·m/m³, and the measured maximum temperature is 180.6 ℃; the output torque of the parallel-connected double PCB stator motor is 103 mN·m, the torque density can reach 1 584.62 N·m/m³, and the maximum measured temperature is 110.5 ℃. Compared with the series configuration under the same working conditions, the temperature rise is smaller, which can effectively improve the PCB motor heating problem.
