DSP-Based Brushless DC Motor Novel Sensorless Drivers with Sine PWM

The design and implementation of the digital signal processing (DSP) based on a brushless DC (BLDC) motor sensorless driver with Sine PWM. Because of dispensable power consumption problems generated by closed-loop speed control methods with speed estimation signal feedback are adopted for improvement. In addition, current feedback is added to the driver for the sake of increasing efficiency. Then, sine wave closes 30¢X, 15¢X, and 8¢X to comparing the improvements for efficiency. Experimental results from a laboratory prototype are shown to verify the feasibility of the proposed scheme. The laboratory results show that current feedback and sine wave closed 8¢X have high efficiency.
