a) About

The LC SimpleFOCMini DC brushless motor driver board uses Texas Instruments' DRV8313 chip. DRV8313 provides three independently controllable half H-bridge drivers, mainly used to drive DC brushless motors. Only the control signal and motor UVM three-phase line need to be connected to control the motor rotation. It supports SPWM and SPVMW control algorithms and does not support traditional 6-step commutation control algorithms. It can be quickly used through Arduino SimpleFOC.

e) Instructions for use

Pin Definition：

Control method：

Here, the Arduino UNO development board is used for control, connect as shown in the following diagram

Pin Description：

The left terminal is for the input signal of the microcontroller, and the right terminal is connected to a 3-phase brushless motor

Install SIimple FOC library in Arduino IDE

Paste the following code in the IDE:

驱动器测试代码

Pay attention to modifying the pin definition to the connection pins of the Simple foc mini driver board and Arduino development board.

// BLDCDriver3PWM driver = BLDCDriver3PWM(pwmA, pwmB, pwmC, Enable pin (optional));
BLDCDriver3PWM driver = BLDCDriver3PWM(9, 5, 6, 8);

Click the upload button to compile and download the program to the Arduino development board Open the serial monitor of the IDE, input T 6.28, and the brushless motor can start rotating
