摘　　要：空心杯电机具有体积小和高功率密度等显著优势,被广泛应用于舵机系统中。针对空心杯电机绕组形式的选择大多凭借经验的问题,以相同跨距、相同转速条件下空心杯电机的输出功率为目标,对绕组形式的选择展开了研究分析。计算建立了六边形和菱形绕组的输出功率数学模型,通过仿真和实物功率测试,验证了理论的有效性。结果表明,在相同转速、相同跨距时六边形绕组形式的电机输出功率高于菱形绕组,且随着长径比的增大,六边形绕组电机输出功率的增量高于菱形绕组,在长径比是1.5~2时,具有更高的输出功率。Hollow cup motors,with significant advantages such as small size and high power density,are widely utilized in servo systems.Addressing the issue of empirical selection of winding forms for hollow cup motors,this study focuses on the output power of hollow cup motors under the same span and speed conditions,conducting research and analysis on the selection of winding forms.Mathematical models for output power of hexagonal and rhombic windings were established through calculations.The validity of the theory was verified through simulation and physical power tests.The results indicate that,under identical speed and span conditions,the output power of motors with hexagonal winding forms surpasses that of rhombic winding forms.Furthermore,as the length-to-diameter ratio increases,the increment in output power of motors with hexagonal winding forms exceeds that of rhombic winding forms.Specifically,when the length-to-diameter ratio falls within the range of 1.5 to 2,motors with hexagonal winding forms demonstrate higher output power.Overall,this research provides insights into the selection of winding forms for hollow cup motors and demonstrates the superiority of the hexagonal winding form in terms of output power.
