500W BLDC Brushless Motor Speed Controller DC 12-36V PWM Driver
BLDC 500W Brushless Motor Speed Controller — DC 12–36V PWM Hall-less Driver Board
Take precise command of your brushless DC motor projects with this compact yet powerful 500W BLDC motor driver board. Designed for hall-less (sensorless) motors, it supports both forward and reverse rotation switching, making it ideal for DIY electronics, robotics, CNC builds, e-bikes, and industrial automation applications. With a wide input voltage range of DC 12–36V and a maximum current of 15A, this versatile controller handles demanding loads with ease.
Key Features
- Forward & Reverse Rotation Control: Built-in direction switching lets you change motor rotation on the fly — perfect for dynamic applications requiring bidirectional movement.
- Flexible Speed Control: Adjust speed via a potentiometer (10–50KΩ recommended) or a 5V PWM signal for seamless integration with microcontrollers such as Arduino or Raspberry Pi.
- Integrated Heat Sink: The driver board comes equipped with an 18mm thick aluminium heat sink for effective thermal management during continuous operation.
- Compact Form Factor: At approximately 63 × 43mm, this neatly laid-out PCB fits easily into tight enclosures and project builds.
- Wide Application Range: Suitable for a broad range of brushless DC motors used in power tools, fans, pumps, e-bikes, CNC spindles, and more.
- Robust Construction: Built from quality PCB and metal components for reliable, long-term performance.

Important Usage Notes
- When testing, use an adjustable power supply in current-limiting mode to verify no-load current and prevent burnout from unexpected power surges.
- Do not short-circuit the three output phases (U, V, W) — this will damage the driver board.
- For high-power operation, monitor heat generation and install a cooling fan if the board runs hot.
- No socket or connecting cable is included — soldering is required. The forward/reverse switch and speed potentiometer must be sourced separately.
- Ensure your soldering iron is properly grounded to prevent induced current from damaging the driver.

Frequently Asked Questions
Q: What types of brushless motors are compatible with this BLDC speed controller?
A: This motor driver board is designed for hall-less (sensorless) brushless DC (BLDC) motors operating within DC 12–36V and up to 500W / 15A. It is commonly used with motors found in power tools, CNC spindles, e-bikes, fans, and pumps. It does not support hall-sensor-based motors.
Q: Can I control the speed using a microcontroller like Arduino?
A: Yes. In addition to a manual potentiometer (10–50KΩ), this BLDC controller accepts a 5V PWM signal, making it fully compatible with Arduino, Raspberry Pi, and similar microcontrollers for automated or programmable speed control.
Q: Does the board come with wires, a potentiometer, or a direction switch?
A: No — the board does not include a socket, connecting cables, a speed potentiometer, or a forward/reverse switch. These components must be sourced and soldered separately. Soldering skills are required for installation.
Q: What should I do if the driver board gets very hot during use?
A: The board features an integrated 18mm heat sink for passive cooling. For high-power or extended-duration use, it is strongly recommended to add an external cooling fan for forced air cooling to maintain safe operating temperatures and protect the driver from thermal damage.
