As people's awareness of energy saving and emission reduction increases, range hoods are a product that is frequently used in home life, and the market needs high-efficiency motors and motor control solutions. Cmsemicon develops an FOC control scheme for this application, which improves the operating efficiency of the motor while effectively reducing the operating noise and vibration of the motor.

CMS32M55xx high pressure range hood program performance characteristics:

> Integrate 12Bits high-speed ADC, multiple high-performance analog operational amplifiers and programmable PGA, 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 torque/constant power control

> Support communication control via UART interface

> Possess excellent CE, ESD performance, EFT>4200V
