For vacuum cleaner applications, Cmsemicon has introduced a FOC application solution based on microcontroller CMS32M57xx. The controller is mainly used for vacuum cleaner motor control.
Performance characteristics of CMS32M57xx vacuum cleaner solution:
> Integrate 12Bits high-speed ADC, multiple high-performance analog operational amplifiers and programmable PGA, streamline peripheral circuits
> Non-inductive FOC, single 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 power control, identification and protection of linear air vents
> Speed control can be as high as 100000+RPM
> Standard output interface: FG, Vsp (or PWM), VCC, GND
> Possess excellent CE, ESD performance, EFT>4200V
|FOC Vacuum Cleaner Development Kit||
The FOC Vacuum Cleaner Development Kit is a low-voltage non-inductive FOC development board developed with CMS32M5733. It supports non-inductive FOC and single-resistance control. It has fast startup, stable operation and ultra-high speed. The kit provides an ideal evaluation environment for developers and supports the development of FOC vacuum cleaners for users. The CMS32M5733 main control chip used in this development board has two operational amplifiers, two PGAs, and multiple high-precision 12-bit ADCs.
