| 摘 要： | 针对稀土永磁无刷直流电机(BLDCM),借助电机本体所固有的三相Hall转子位置传感器,通过空间矢量脉宽调制(SVPWM)控制技术,实现了BLDCM的正弦波电流驱动。实验结果表明,与方波电流驱动相比,采用正弦波驱动可有效减小BLDCM的运行噪声,降低转矩脉动,实现低成本家用电器等领域的静音运行。

| Abstract: | Adriving method of Brushless DC Motor(BLDCM) with sinusoidal current was presented.Space vector pulse width modulation(SVPWM) techniques was adopted to generate sinusoidal current for motor three-phase windings according to the rotor position information provided by three-phase Hall sensors.The experimental results show that the approach is more effective for the minimization of the torque ripple and audible noise than the traditional square current driving method,and practical for quiet operation in low co... |
