Aiming at the application of air purifiers in the home, medical and industrial fields, Cmsemicon has launched a cost-effective air purifier motor control solution. Using SVPWM space voltage vector modulation technology, it has smaller harmonic components and torque ripple, and the peripheral circuit is streamlined to provide a complete solution.

Performance characteristics of CMS32M55xx air purifier motor control program:

> Integrated 12Bits high-speed ADC, multiple high-performance analog operational amplifiers and programmable PGA, P+N drive, streamlined 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
