Research on Characteristic of Sinusoidal Current Driving Method for BLDCM with Hall Position Sensor

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 cost home appliances.
