Motherboard specifications: Product name: 200W brushless DC motor driver with Hall effect Model: XY-BLDC Working voltage: 12-30V Maximum current: rated 7A, peak value 10A Maximum power: 200W Overcurrent protection: Yes Positive and negative: Yes Brake: Yes Speed control PWM: Yes Speed control analog quantity: Yes Product size: length 80MM*width 30MM*height 10MM External signal input description: 1. When the external PWM signal is input, the amplitude is 5V, and the recommended PWM frequency is 1K-10KHz. 2. For analog input, you can use the on-board 5V, GND external potentiometer (resistance 10K-100KΩ) to adjust the speed, or you can input (0-5V) analog externally, but it needs to be connected to the GND on the board. 3. For forward and reverse rotation control, the motor needs to stop rotating and then perform forward and reverse operation. It is strictly forbidden to change direction during the rotation of the motor, which will cause damage to the circuit board. In addition, after removing the short-circuit cap, the steering switch can be connected externally for operation. 4. 5V, GND The motherboard comes with a 5V power supply (power can be supplied externally, the current does not exceed 10mA) 5. Speed pulse signal output, the amplitude is 5V, each pulse represents one revolution of the motor. Precautions: 1. There is no fuse in the power supply circuit on the main board. Jianyi has added it himself. Reverse connection of the positive and negative poles of the power supply will cause permanent damage to some chips on the board. 2. There is sampling over-current protection at the output of the motor during normal operation. Because the power and current of the module are very large, please do not artificially short-circuit when the module is not working normally. Once the short-circuit, the circuit may be burnt and the tube may burst. Please test the machine for the first time. Please use a small current and low voltage test. After ok, turn on the high current and high voltage. Because it is a bare board module, please pay attention to the insulation of the wiring head. It is strictly forbidden that strong voltage touches the board parts. 3. When the operating power of the drive module exceeds 100W or the operating environment exceeds 30°C, in order to ensure the normal operation of the circuit for a long time, it is necessary to provide external air cooling for the circuit board for heat dissipation. 4. After receiving the goods, if you are not sure about the wiring and use, please contact us as soon as possible. Even if there is a problem with the use of the product, it can be handled properly through friendly negotiation. Debugging instructions: Please power on and test the machine after reading and understanding, it is very important, very important! ! ! After receiving the driver board, check whether the interface can correspond to the interface of your brushless motor. 1. Generally, there are 5 Hall cables or interfaces on brushless motors, two of which are Hall power supply lines and three are Hall signal lines. It should be distinguished, especially Hall power supply lines (Hall power supply lines generally use red and black lines). Don’t make a mistake. The three Hall signal lines are generally marked with abc, and there are also three ports Ha, Hb, Hc and similar characters on the driver board. 2. There are three thicker phase wires on the motor. There are also three phase wires on the drive board. They are marked with MA MB MC and similar characters, and they are connected respectively. After confirming that they are correct, the main power supply can work normally. (If the interfaces are correctly mapped according to the label, the power will not work, and the possibility that the manufacturer’s label is not standardized or other reasons is not ruled out. Please debug according to the following unclear) If you do not know the definition of the motor phase line and the Hall line, you can connect the three phase lines of the motor and the drive phase line interface arbitrarily, and at the same time connect the three signal lines of the Hall line to the Hall interface on the drive board (but two The root Hall power supply line must find a way to find and connect it, remember!!!) Then, when the power is turned on for the first time, debug with low voltage and low current (if possible, use constant current power supply voltage to adjust to 7-12V current 1- 2A), then through the arbitrary sequence of changing the three Hall wires (change any two between the three Hall signal wires of the motor and the drive Hall interface, each time the power-on test is changed), until it can run smoothly after power-on It shows that the wiring is correct. When the wiring is incorrect, do not debug with high current or high voltage, otherwise there is a risk of damaging the drive board. If the three Hall signal wires are exchanged, if the corresponding connection is correct, the motor will run silky smoothly after power-on, and start at low speed. The torque will be large; if The sequence of the three Hall signal lines does not correspond to each other, and they generally have the following characteristics: 1. After power on, the motor cannot start normally and does not respond, or it only shakes once when it starts and cannot rotate normally. 2. It is difficult to start with a slight jitter, and sometimes it needs to be manually turned up. 3. The motor can turn in one direction, but not in the other direction, and some have a slight bath sound 4. The motor starts to vibrate and is weak and has a bath sound. The current is large and the power tube is obviously heating up. Payment Method Shipping Policy Feedback Payment Method Payment must be received in 5 business days of auction closing.
