摘　　要：针对有限元法计算磁阻型球形电机转矩耗费大量计算时间的问题,本文采用虚功法建立了磁阻型球形电机的转矩模型。首先利用电磁分析软件仿真出单个定子线圈的电感变化规律,并通过双线性插值获得电感模型。将得到的电感分别沿经纬度方向进行微分处理,得到二维转矩数值。再通过坐标变换,将二自由度转矩转换为三自由度转矩。最后搭建基于动态转矩传感器的转矩测量平台,测出实验转矩并将其与解析结果进行对比,验证了转矩模型的有效性。In this paper,the torque model of reluctance spherical motor is developed based on the virtual power method for the problem that the finite element method takes a lot of computation time to calculate the torque of reluctance spherical motor.First,the inductance variation law of a single stator coil is simulated using electromagnetic analysis software,and the inductance model is obtained by bilinear interpolation.The obtained inductance are differentiated along the longitudinal and latitudinal directions respectively,to obtain two-dimensional torque values.The two-degree-of-freedom torque is then converted to three-degree-of-freedom torque by coordinate transformation.Finally,a torque measurement platform based on the dynamic torque sensor is built,and the experimental torque is measured and compared with the analytical results to verify the validity of the torque model.
