About

LC JY02 DC brushless Hall drive board, using JY02 chip as the core, combined with FD6288T gate drive IC, provides efficient and stable DC brushless motor drive solution

This drive board supports precise control of three-phase brushless motors. Simply connect the UVW three-phase wires of the motor to control its rotation. It supports SPWM drive mode and can adjust the speed by inputting PWM signals through a rotary potentiometer. At the same time, the motor can be controlled in both forward and reverse directions through pins. The drive board has overload, over temperature, and locked rotor protection functions to ensure safe and stable operation of the motor

Instructions for use

1. Power the drive board (DC 12-37V)

2. Connect the potentiometer (5V-VR-GND pin) and rotate the potentiometer knob counterclockwise to the lowest gear to prevent the motor from automatically turning on when powered on

3. Connect the output line of the brushless motor (the three wires of the three-phase brushless motor can be connected in any order, and changing the connection order of any two wires can change the rotation direction of the motor)

4. Slowly rotate the potentiometer knob clockwise, and the motor will start to rotate, as shown in the figure:

Attention:

1. This module has a fast response speed, and the instantaneous starting current is very high when the full throttle is powered on. Please leave a margin. It is not recommended to start under high voltage and high power full throttle conditions, as this operation may damage the power transistor and chip.

2. There is no fuse in the power supply circuit on the motherboard. It is recommended that users add it themselves. Reversing the positive and negative poles of the power supply can cause permanent damage to some chips on the board

3. During normal operation, there is motor stalling protection. Due to the high power and current of the module, please do not artificially short circuit when the module is not working properly. Once short circuited, there is a possibility of burning the circuit and bursting the tube. For the first wiring test, please use a low current and low voltage (12V voltage) to test. After the motor is working normally, adjust the current and voltage again

4. Do not connect motors that do not match or differ significantly from the voltage, current, or power of the drive module to avoid inexplicable damage
