Speed control of the 12-step sensorless drive for a brushless dc motor

The 12-step sensorless drive scheme requires an interval to detect the zero crossing of the back emf. The voltage regulating pulse-width modulation (PWM) is commonly used for the speed control of a motor. However, it induces the fluctuation of the back emf and makes the zero-crossing detection diffi...
