5V 12V Brushless PWM Motor Speed Controller Driver Controller Board

brushless DC motor drive board
In the past, the drive board of brushless motor sold was easy to burn the drive chip when the motor line contact was poor, the wrong line was connected, the load was too large, and the output end was short-circuited. Now, the improved drive board won't burn the chip no matter how the motor is connected to the wrong line, the load is too large, and the motor line is short-circuited, so you can feel free to operate it.
The drive board can drive micro 3-wire or 4-wire hall free brushless motors such as hard disk brushless motor and optical drive brushless motor.
The drive board has voltage reverse connection protection, overcurrent protection and short circuit protection. The wiring is simple and easy to use.
The hard disk can be rotated with a voltage of 7-12V. The higher the voltage, the faster the rotation speed, up to about 10,000 revolutions.
How to identify the common port of a 4-wire motor: measure the four terminals respectively with the gear of resistance *1 of the multimeter. If the resistance of one terminal is the smallest and equal to that of the other three terminals, then this terminal is the com terminal, that 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.

[driving voltage] DC: 7-12V
[Working current] ≤1.2A
[speed regulation range] 0%-100%
[Phase inversion control] Yes
[voltage reverse connection protection] Yes
[overcurrent protection] includes:
[short circuit protection] Yes

Note: after the short-circuit overcurrent protection of the brushless drive board, the power indicator light goes out. At this time, the power supply of the drive board should be cut off, and the power supply to the drive board can be supplied after the cause of the overcurrent is handled. The LED power indicator light can work normally when it is on.
