This is a Brushless Motor Driver Controller Board For 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.
- Driver voltage: DC7-12V
- Working voltage: ≤1.2A
- Speed adjust:0%-100%
- Color: Green and Black
