分析了二相混合式步进电动机的谐波转矩，提出了一种采用电流前馈控制来减小谐波转矩的方法，并建立二相混合式步进电动机的模型，进行了仿真。仿真结果表明，这种方法能有效减小谐波转矩，降低步进电动机的振动。
This paper analyzes the harmonic torque of the 2-phase hybrid stepping motor and puts forword a method of using current feedforword control to reduce the harmonic torque.Further along,a simulation model of 2-phase hybrid stepping motor is established and the simulation is performed.The result of simulation verifies that with this method the harmonic torque is decreased and the vibration is weakened effectively.
