Micro brushless DC motor drive board
The brushless motor drive board sold before will burn the drive chip when the motor wire is poorly connected, the wrong wire is connected, the load is too large, and the output terminal is short-circuited. Now the improved drive board no matter how the motor is connected to the wrong wire, how large the load, and the motor The chip will not be burnt even if the line is short-circuited, so you can safely operate at will.
This drive board can drive miniature 3-wire or 4-wire Hallless brushless motors such as hard disk brushless motors, optical drive brushless motors, etc.
The driver board has voltage reverse connection protection, over current protection, short circuit protection, simple wiring, and very worry-free to use.
The hard disk motor can be rotated at a voltage of 7-12V. The higher the voltage, the faster the speed, and the maximum can reach about 10,000 revolutions.
How to identify the common port of a 4-wire motor: Measure the four terminals with the resistance *1 of the multimeter. One of the terminals has the smallest and equal resistance to the other three terminals. Then this terminal is the COM terminal, that is, the common Terminal. The driver 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.
【Drive voltage】DC 7-12V
【Working current】≤1.2A
【Speed adjustment range】0%-100%
【Phase Inversion Control】Yes
[Voltage reverse connection protection] Yes
【Overcurrent protection】Yes
【Short Circuit Protection】Yes
Note: The power indicator of the brushless driver board is extinguished after short circuit overcurrent protection. At this time, cut off the power supply of the driver board and deal with the cause of the overcurrent before supplying power to the driver board. After the LED power indicator lights up, it can work normally.
