FOC vacuum cleaner, low voltage sensorless FOC solution, main control chip CMS32M5733Q048 [Copy link]

The FOC vacuum cleaner development kit is a low-voltage sensorless FOC development board developed using CMS32M5733. It supports sensorless FOC and single resistor control, and has fast startup, smooth operation, and ultra-high speed. The kit provides an ideal evaluation environment for developers to support the development of user FOC vacuum cleaners. The CMS32M5733 main control chip used in the development board has two op amps, two PGAs, and multiple high-precision 12-bit ADCs. It is widely used in typical motor control fields such as sine wave vacuum cleaners, electric two-wheelers, variable frequency air conditioners, variable frequency washing machines, high-pressure and high-speed hair dryers, etc.
