The "DC7V-12V Brushless Motor Driver Controller Board for Hard Drive Motor 3/4 Wire" is an electronic module designed to control brushless motors typically found in hard drives.

Here's some information about the DC7V-12V Brushless Motor Driver Controller Board :

Input Voltage: This controller board is designed to operate within a voltage range of 7V to 12V. You should provide a power supply within this range to power the brushless motor and the controller.

Brushless Motor Control: The primary purpose of this board is to control brushless motors, which are commonly used in hard drives. Brushless motors offer advantages such as long lifespan, high efficiency, and minimal maintenance compared to brushed motors.

3/4 Wire Compatibility: This controller board is compatible with both 3-wire and 4-wire brushless motors. Different types of brushless motors may have varying wire configurations, and this controller can accommodate both.

Speed Control: The board typically allows you to control the speed of the brushless motor. Depending on the design, this can be achieved through pulse-width modulation (PWM) or other speed control mechanisms.

Direction Control: Depending on the motor and controller setup, you may be able to control the direction of the brushless motor's rotation. Some applications may require bidirectional control.

Protection Features: Some controller boards include protection mechanisms such as overcurrent protection to prevent damage to the motor or the controller in case of excessive current draw.


This type of controller board is often used in projects or applications where precise control of a brushless motor is needed. Apart from hard drives, brushless motors are also used in various applications, including drones, cooling fans, and robotics.

This is a Brushless Motor Driver Controller Board For a Hard Drive Motor. The driver board has voltage reverse connection protection, over-current protection, short circuit protection, simple wiring, and worry-free use. The hard disk motor can be rotated at a voltage of 7-12V. The higher the voltage, the faster the speed, which can reach about 10,000 revolutions.

How to identify the common port of a 4-wire motor:

Measure the four terminals with the resistance x 1 of the meter.

One of the terminals and the other three terminals have the smallest and equal resistance, then this terminal is the COM terminal, Which is the common terminal.

The driver board automatically recognizes the 3-wire or 4-wire brushless motor and the 4-wire brushless motor can also be disconnected from the COM line.
