DC 7-24V 200W BLDC 3-Phase Brushless Motor Driver Board, Hallless Speed Controller

DC 7-24V 200W BLDC Three-Phase Motor Driver Board This compact driver board provides reliable speed control for three-phase brushless DC motors without Hall sensors. Operating across a wide 7-24V DC input range and supporting motors up to 200W, it offers a straightforward solution for a variety of low-voltage motor applications. The board is available in two control versions, each suited to different operating preferences. Potentiometer Speed Control Version The potentiometer version allows direct, tool-free speed adjustment. A standard rotary potentiometer regulates motor speed without the need for any external control signals or additional wiring. Turning the potentiometer clockwise increases speed, while turning it anticlockwise reduces it. This makes the board particularly convenient for bench testing, small machinery, or any setup where simple manual speed adjustment is preferred. One-Button Version with Power-Off Memory The one-button version simplifies operation further with a single control button. It supports free switching between acceleration and deceleration modes, allowing you to ramp motor speed up or down as required. This version also includes a power-off memory function, so your last speed setting is retained when power is removed and automatically restored the next time the board is switched on. This is especially useful in installations where consistent repeatable speed is important. Wide Voltage and Signal Compatibility The board accepts a broad 7-24V DC supply, making it adaptable to many common power sources. The potentiometer version additionally supports a 0-5V analogue simulation signal input, allowing integration with external control systems where remote or automated speed setting is needed. The high-performance, low-volume design keeps the board compact while delivering dependable brushless motor drive performance. What to Consider Please note that this driver is designed for brushless motors without Hall sensors. Ensure your motor falls within the 200W power rating and 7-24V operating range before use. The potentiometer version requires a suitable potentiometer for speed adjustment, which is not included with the board.
