For the three-phase low-voltage fan motor drive solution, Cmsemicon launched a cost-effective low-voltage fan solution. The scheme adopts SVPWM space voltage vector modulation technology, which has smaller harmonic components and torque ripple, and the peripheral circuit is simplified, providing a complete solution.

Performance characteristics of CMS32M55xx floor fan motor control program:

> Integrate 12Bits high-speed ADC, multiple high-performance analog operational amplifiers and programmable PGA, P+N drive, streamline peripheral circuits

> Non-inductive FOC, dual resistance control mode

> Self-convergence and direct closed-loop startup algorithm, adapt to different load startup, 100% startup success

> Good start effect in forward and backward wind, fast and stable start, no out of step, smooth operation and low noise

> Constant speed control

> Standard output interface: FG, Vsp (or PWM), VCC, GND
