摘要
为了克服传统直流电动机因机械换向带来的火花、噪声等缺点,变磁极性直流电动机成为电机无刷化的一个新的发展方向。变磁极性直流电动机采用磁极换向的方式产生旋转磁场,从而带动通以直流电的电枢转动。建立起电压、转矩方程,并推导出电机的机械特性方程,对变磁极性直流电动机的进一步研究有参考价值。
In order to overcome traditional DC motor disadvantages such as spark because of mechanical commutation,magnetic polarity changeable DC motor has become a new development of motor brushless.Magnetic polarity changeable DC motor uses pole commutation to produce rotation magnetic field which drives armature rotation.Equation of voltage and torque was established to deduce the mechanical properties formula,which has some reference for the further study on magnetic polarity changeable DC motor.
