Frequently Asked Questions
Q: What types of motors is this FOC driver board compatible with?
A: This motor driver board supports three-phase PMSM (Permanent Magnet Synchronous Motors), BLDC (Brushless DC) motors, general brushless motors, and pan-tilt gimbal motors operating at 12V–48V with up to 200W of power.
Q: What communication interfaces does this driver board support?
A: The board features two communication interfaces: RS485 using the Modbus RTU protocol (38400 baud, 8N1) and CAN bus, making it suitable for integration into industrial automation, robotics, and multi-axis control systems.
Q: Does this board require an external encoder?
A: No. The board includes an onboard magnetic encoder chip, allowing it to detect shaft position directly without the need for a separate external encoder. This enables a compact, integrated motor drive solution.
Q: What protection features are built into this motor driver board?
A: The board includes built-in under-voltage, over-voltage, motor stall, and overheating protection circuits to help safeguard both the driver and the connected motor during operation.
Q: Is this board compatible with both STM32 and APM32 microcontrollers?
A: Yes. The driver is compatible with both the STM32F103C8T6 and APM32F103C8T6 microcontrollers, which are fully interchangeable in terms of software and hardware on this board.
