Mạch điều khiển không chổi than 5V-12V cho động cơ ổ cứng

100% brand new and high quality Material: Plastic and Electrical components Color: Green and Black The driver board can drive hard disk brushless motors ,CD-ROM brushless motor and so on ， the micro 3-wire or 4-wire without hall brushless motor , It's have reverse voltage protection , Over current protection , Phase inversion control Driver voltage : DC5-12v Working voltage : ≤1.2A Speed adjust :0%-100% Note : Brushless motor line of receiving terminal drive plate must be pressed sturdiness, poor contact will lack of phase operation and burn out the chip.Board terminals fixed screw clearance, please use coarser line connected to the board. How to identify four line motor public port: use the resistance of the multimeter * gears test this four terminal,One of the terminals and the other three terminal resistance value of the minimum and equal So it's COM terminal Size:6*4.5cm/2.36"*1.77" Quantity: 1Pc Note: Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
