7V-12V DC Motor Driver Controller Optical Drive Hard Disk Motor Controller Brushless DC Motor Driver Board
Product Description
Brushless DC Motor Drive Board Speed Control Board Optical Drive Hard Disk Motor Controller 7V-12V The brushless motor drive board sold before will burn the drive chip when the motor wire is poorly connected, the wrong wire is connected, the load is too large, and the output terminal is short-circuited. Now the improved drive board no matter how the motor is connected to the wrong wire, how large the load, and the motor The chip will not be burnt even if the line is short-circuited, so you can operate at will. This driver board can drive miniature 3-wire or 4-wire Hallless brushless motors such as hard disk brushless motors, optical drive brushless motors, etc. The driver board has voltage reverse connection protection, over current protection, short circuit protection, simple wiring, and very worry-free to use. The hard disk motor can be rotated with a voltage of 7-12V. The higher the voltage, the faster the speed, and the maximum can reach about 10,000 revolutions. How to identify the common port of a 4-wire motor: Measure the four terminals with the resistance *1 of the multimeter. One of the terminals has the smallest and equal resistance to the other three terminals. Then this terminal is the COM terminal, which is the common Terminal. The drive 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
The power indicator of the brushless driver board is extinguished after the short circuit overcurrent protection of the brushless driver board. At this time, the power supply of the driver board should be cut off, and the driver board can be powered after dealing with the cause of the overcurrent. After the LED power indicator lights up, it can work normally.
