Are you worried about motor control selection for your vacuum cleaner project? This vacuum cleaner solution is based on the reference design of Microchip dsPIC33CDV. This design can easily drive three-phase PMSM or BLDC motors with excellent performance and affordable cost.

This solution uses dual-loop digital control of current inner loop + voltage outer loop. The switching frequency can reach 100KHz. It is equipped with protection functions such as short circuit, overcurrent, undervoltage, and overvoltage. The communication interface UART transmits data externally.
