7V-12V DC Brushless Motor Driver Controller Board For Hard Drive Motor 3/4 Wire

7V-12V DC Brushless Motor Driver Controller Board For Hard Drive Motor 3/4 Wire For Hard Drive Motor 3/4 Wire 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.   Features:   Voltage reverse connection protection Over-current protection Short circuit protection Simple wiring   Specifications:   Driver voltage: DC7-12V Working voltage: ≤1.2A Speed adjust:0%-100% Color: Green and Black Size:6.3×4.5cm 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. Note: This driver board is suitable for controlling hard drive motors within the specified voltage and current range. It provides protection features and simple wiring for ease of use. Package Includes: 1 x 7V-12V DC Brushless Motor Driver Controller Board For Hard Drive Motor 3/4 Wire
