Бесщеточная плата двигателя постоянного тока управления скоростью оптического привода контроллер жесткого диска 7-12

[Drive voltage] DC 7-12V

[Working current] ≤1.2A

[Speed range] 0%-100%

[phase-shifting control]

[voltage reverse connection protection]

[Overcurrent protection]

[Short circuit protection]

The driver board can drive a micro 3-wire or 4-wire Hallless brushless motor such as a hard disk brushless motor or an optical drive brushless motor.

The drive board has reverse voltage protection, over current protection, short circuit protection, simple wiring, and is very worry-free to use.

Hard disk motor can use 7-12V voltage to turn, the higher the voltage, the faster the speed, up to 10,000 rpm.

How to identify the common port of the 4-wire motor: use the multimeter's resistance *1 gear position to measure the four terminals, one of the terminals and the other three terminals have the smallest and equal resistance value, 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 not connect the COM line.How to identify the common port of the 4-wire motor: use the multimeter's resistance *1 gear position to measure the four terminals, one of the terminals and the other three terminals have the smallest and equal resistance value, then this terminal is the COM terminal, which is the common Terminal.

Note: After the short-circuit over-current protection of the brushless driver board is turned off, the power indicator will be off. At this time, the power supply of the driver board should be disconnected. After the cause of the over-current is processed, the driver board can be powered. The LED power indicator will work normally after it is lit.
