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
|Air Purifier Development Kit||
The air purifier development kit is a low-voltage silent FOC development board developed with CMS32M5524. It supports dual resistance control, uses SVPWM space voltage vector modulation technology, has small harmonic components and torque ripples, and supports PWM pulse width speed regulation and AD Two modes of speed regulation. The kit provides an ideal evaluation environment for developers and supports the development of users' air purifiers. The CMS32M5524 main control chip used in this development board has an operational amplifier, two PGAs, multiple comparators, and multiple high-precision 12-bit ADCs.
