Through cutting-edge technological innovation and optimization, Geehy proudly presents its mass production solution featuring the APM32F035 motor control dedicated MCU. This revolutionary solution incorporates sensor-based Field-Oriented Control (FOC), offering a streamlined peripheral circuit, reduced energy consumption, and minimized noise. It also experiences a smoother startup and shorter braking time with enhanced efficiency.

Overview of APM32F035 Strong Magnetic Stirrer Solution

The APM32F035 MCU serves as the central controller in this motor control application. Responsible for collecting Hall signals, current, and voltage inputs, the MCU executes motor control logic, receives commands, and provides real-time feedback on motor status. Detecting Hall signals, bus voltage, and motor phase current internally, the APM32F035 generates six sets of complementary PWM signals via Timer1, ensuring efficient, smooth, and quiet motor operation. Importantly, the APM32F035 includes four built-in operational amplifiers, eliminating the need for an external one during motor phase current sampling.
