Interface Guide
- U / V / W: Three-phase output lines — connect directly to your brushless motor
- VCC / GND: Main DC power supply input (external DC power source required; battery not included)
Ideal Applications
This sensorless BLDC driver board is purpose-built for low-power, small-form-factor brushless motors found in:
- Cooling fans and ventilation systems
- Air pumps, water pumps, and oil pumps
- Embedded industrial control systems
- DIY robotics and electronics projects
- Compact motor-driven gadgets and appliances
Note: Default timing is calibrated for mid-range loads. Not recommended for continuous full-load, high-power motor operation. If sustained high-load use is needed, add active cooling (e.g., a small fan) to the board.
Important Safety Precautions
- No onboard fuse: We strongly recommend adding an external fuse to your power supply circuit. Reversing the positive and negative power connections — even momentarily — can cause permanent chip damage.
- Motor stall protection: The board includes stall protection during normal operation. Do not manually short-circuit the module when it is not operating correctly. Always start with low voltage and low current during initial wiring tests.
- Match motor specs: Only connect motors whose voltage, current, and power ratings are compatible with this driver module. Mismatched motors may result in unexpected board failure.
Package Includes
- 1× 60W Three-Phase Brushless Motor Speed Controller (BLDC Driver Board)
- 1× Cable
Note: Colors may vary slightly from images due to screen calibration differences. Allow ±1–3 cm tolerance due to manual measurement.

Frequently Asked Questions
Q: Does this BLDC speed controller require Hall sensors to operate?
A: No — this is a sensorless brushless motor driver. It operates without Hall sensors, making it simpler to wire and ideal for motors that lack built-in Hall effect sensors. It uses back-EMF detection for commutation.
Q: What types of motors is this 60W BLDC driver board compatible with?
A: This driver board is compatible with small three-phase DC brushless motors rated within the 6–20V, up to 3A, and up to 60W range. Common applications include fan motors, air/water/oil pumps, and other compact sensorless brushless motors. Always match motor voltage, current, and power specs to the driver's rated limits.
Q: Can I use this motor speed controller in an embedded or custom electronics project?
A: Yes. Its compact size (34mm × 27mm × 11mm) and low-voltage DC input make it well-suited for embedded systems, DIY robotics, and custom electronics builds. It can be integrated directly into your circuit with an external DC power supply connected to the VCC and GND terminals.
Q: What happens if I accidentally reverse the power supply polarity?
A: Reversing the positive and negative power connections — even briefly — can cause permanent, irreversible damage to the onboard chips. There is no onboard reverse-polarity protection, so it is strongly recommended to add an external fuse and double-check polarity before powering on.
