Brushless Motor Driver Board, BLDC Speed Controller, 3-Phase Sensorless Control Module

Safety Notes for Installation This brushless motor driver board has no fuse in the power supply circuit on the main board, so you will need to add one yourself. Take care to connect the positive and negative terminals of the power supply correctly, as reversing the polarity can cause permanent damage to some chips on the board, even if the power is only connected for a second. During normal operation, the board includes motor stall protection, so please do not artificially short-circuit the output when the motor is not functioning correctly, as this may blow the circuit trace. For your first wiring test, use a low-current, low-voltage supply to confirm the connections are correct before running the motor under load. Motor Compatibility This driver board is designed for use with brushless three-phase DC motors of equivalent current and power ratings. It operates as a sensorless controller, meaning it does not require Hall sensors to regulate motor speed, making it a straightforward choice for a wide range of BLDC motor projects.
