Based on the APM32F035 motor control MCU, Geehy’s canned motor pump solution elevates the entire system to achieve high-efficiency and energy-saving levels comparable to IE3 standards. The compact and stable circuit design offers superior cost-effectiveness compared to traditional approaches. The APM32F035, acting as the main control chip, handles signal sampling (bus voltage, current, IPM temperature), executes motor control logic, and receives control commands.

With abundant resources, the APM32F035 MCU enables simplified circuits and reduced interference, and the M0CP coprocessor supports more intricate calculations with shorter processing times. This boosts motor operational efficiency, introducing application protection functions like fault indication, bidirectional rotation switching, software, and hardware speed control, input over/under-voltage protection, software and hardware over-current protection, phase loss protection, and stall protection. These features ensure the motor operates efficiently, smoothly, quietly, and safely.
