Micro DC brushless motor drive board

The brushless motor drive board that was previously sold was easy to burn the driver chip when the motor cable was in poor contact, the error line, the load was too large, and the short circuit of the output end was easily burned.The short circuit will not burn the chip anymore, you can rest assured to operate at will.

This driver board can drive the micro -3 or 4 -wire no -brushless motor of the micro -brushless motor, optical drive without brush motor

Driven board has voltage reflection protection, over -current protection, short -circuit protection, simple wiring, and very worry -free use.

The voltage of the hard disk motor can be rotated by 7-12V. The higher the voltage, the faster the speed, and the maximum can reach about 10,000 rpm.

How to identify the public port of the 4 -wire motor: Map the four terminals with the gear of the multimeter's resistance*1, one of which is the smallest and equal to the resistance value of the other three terminals, so this terminal is the COM terminal, which is the public, that is, the public, that is, the public, that is, the public, that is, the publicTerminals.The driver board automatically identifies the 3 -line or 4 -line brushless motor, and the 4 -line brushless motor can also be connected to the COM line.

【Drive Voltage】 DC 7-12V

【Working current】 ≤1.2A

[Speed ​​regulation range] 0%-100%

[Turn on phase control] Yes

【Voltage Reverse Protection】 Yes

[Overcurrent protection] Yes

[Short -circuit protection] Yes

Note: After the brushless drive board is short -circuited, the power indicator is extinguished. At this time, the power supply of the drive board should be broken, and the reasons for the overcurrent should be powered on the drive board.
