Product Description:
This driver board can drive hard disk brushless motor, optical drive brushless motor and other miniature 3-wire or 4-wire no Hall brushless motor driver board has voltage reverse protection, overcurrent protection, short circuit protection, wiring is simple to use, save heart. Hard disk motor using voltage 7-12V can turn, the higher the voltage the faster the speed, the peak can reach about 10000 rpm. How to identify the common port of the 4-wire motor: with the multimeter resistance * 1 gear were measured these four terminals, one of the terminals and the other three terminals of the resistance value zui small and equal, then this terminal is the C0M terminal, that is, the
Common terminal. The driver board automatically recognizes 3-wire or 4-wire brushless motors, and 4-wire brushless motors can also not be connected to the COM cable.
Product parameters:
Driving voltage: DC7-12V
Working current: ≤1.2A
Speed control range: 0%-100
Phase control: Yes
Voltage reversal protection: Yes
Over-current protection: Yes
Short-circuit protection: Yes
Caution:
Brushless driver board short-circuit overcurrent protection after the power indicator light off, this time to cut off the power supply of the driver board, deal with the cause of overcurrent and then give the driver board power supply, LED power indicator light up after the normal work!
