7V 12V Brushless DC Motor Driver Controller Board with Reverse Voltage Over Current Protection for Hard Drive Motor 3/4 Wire

Turn the voltage up when starting or turn the switch down to the minimum when starting

Full start current protected

Note: After the brushless drive board shorted out the current protection, the power indicator is off, then the power supply of the drive board should be cut off, and the cause of better than the current is dealt with and then the power supply of the drive board, the LED power indicator will be able to work normally after the light is on

I did.

Product Introduction:

Improved version of the old brushless motor drive board when the motor line contact is poor, the wrong line, the load is too large, the output short circuit is very easy to burn the driver chip, now the improved drive board no matter how you connect the motor wrong line, the load is large, the motor line short circuit will not burn the chip, you can rest assured at will operation.

Product features:

The driver board can drive hard disk brushless motor, drive brushless motor and other miniature 3 or 4 wire hall brushless motor driver board has voltage reverse protection, over current protection, short circuit protection, simple wiring, easy to use. The hard disk motor can be turned with a voltage of 7-12V, and the higher the voltage, the faster the speed can reach a maximum of about 10,000 revolutions.
