Notes:
1. Mini DC brushless motor controller adopts single chip with high integration, drive motor does not need Hall sensor, power supply is regulated DC power, can not be connected to AC power, supply current should be enough, please indicate the voltage and current range of parameters on the webpage Used internally. There are many types of brushless motors, and there are also matching with the governor. We can't guarantee that all brushless motors can be applied. Please ensure that the wiring is correct and then power on the test machine (the first time the power is tested, the motor is not known.) In the case, it is recommended that the input voltage be about 5.5-6V. After the test machine is OK, increase the voltage according to the working condition of the motor and the need.
  2. Mini three-phase brushless governor, the input power supply has reverse connection protection, the reverse will not burn, and the internal integrated overcurrent protection circuit. During operation, there is a set of current limiting detection circuit inside the chip, which works normally. The continuous current is within 1.5A and the peak value is 2A. Please cooperate with the motor with the same working voltage, current and power. If the parameters are too far apart, it is not suitable for use. In conjunction with the use, there will be some unfavorable phenomena, the risk of burning the main chip, the motor line lacking phase blocking protection, and the LED light indication on the main board, but not suitable for a long time, it is strictly prohibited to have poor contact of the three phases of the motor. (The Hall brushless motor is not required to start normally. In the initial stage of the startup, a set of starting currents will be forced inside the chip. In order to achieve a certain torque, the starting current will be increased, and the motor will be rotated rapidly, such as the motor. A bad line contact will give a false start signal. If the input voltage is high, the impact is relatively large, and it is most likely to burn the driver chip.
  3. The following points should be noted when this brushless driver is equipped with a brushless hard disk motor: (1) The hard disk motor on the market generally has three lines and four lines. The three wires of the three-wire motor are directly connected to the W V U on the drive board. It is not necessary to distinguish the order, just pick it up, but it must be securely wired. The four-wire motor has a common line COM. It must be found out of the public line (the public line is a collection of three lines, generally thicker) and does not need to be connected. (The public line must be separated. If the public line is not separated, mix Connected to the three phase lines, the motor can not be fully activated, generally it will stop after a few shakes. For a long time, there is the possibility of damage to the motherboard driver. Be sure to pay attention!!!) The other three wires are connected to the WVU on the motherboard. The power supply of the hard disk motor within 7200 rpm is between 5-12V, not more than 12V, the first power supply, in the case of not knowing the motor, it is recommended to use the 5.5-6V test machine, and then increase the voltage according to the actual situation after normal operation. The hard disk motor generally has a fast internal resistance and a small internal resistance. Most of them are used. Jianyi works well in the voltage of 5-9V, and 12V can work. After our actual test, because the motor is second-hand and the speed is fast, there is a certain resistance, the motor is very hot, and the risk of easy burning is also caused by improper operation. The internal resistance of the motor above 7200 rpm is smaller. It is recommended that the input voltage be 5-7V, not connected to 12V. (3) Power supply voltage regulation, pure DC power, it is best to provide more than 1.5A current, the power quality is not good, the current is insufficient. , the motor will not start or it is difficult to start. In this case, you can try another power supply.
  4. This brushless driver is mainly used for three-phase brushless motors with a power not exceeding 15W, and cannot be used to drive brush motors.   Package include:1pc*controller
