一种用于永磁无刷直流电机转矩脉动最小化的简单电压调制方案

This paper presents a simple dc-link voltage modulation scheme to minimize the commutation torque ripple in a permanent magnet brushless dc motor (PMBLdcM). Maintaining a constant current in the noncommutating (NC) phase helps to minimize the torque ripple, which can be achieved by boosting the motor input voltage whenever two phase currents are undergoing commutation. At low speeds, since the req...
