Effect of winding form on power of hollow cup motor
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.
