LC-EM-1117

Product Name

SimpleFOCMini DC brushless motor drive board FOC control driver SVPWM control algorithm

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

Pin Description

Number	Pin	Description	Explanation
1	VCC	Input power supply positive terminal	Input power supply 8~30V
2	GND	Input power negative terminal
3	IN1	Channel 1 Input	IN1 is high, M1 is also high, IN1 is low, M1 is also low
4	IN2	Channel 2 Input	IN2 is high, M2 is also high, IN2 is low, M2 is also low
5	IN3	Channel 3 input	IN3 is high, M3 is also high, IN3 is low, M3 is also low
6	EN	Input enable	Simultaneously control channel 1, channel 2, and channel 3 enable, input is valid when high level is reached
7	3.3V	3.3V power supply	3.3V power supply output, maximum current 10mA
8	RESET	Reset input	Reset chip, while prohibiting output, low level is effective
9	SLEEP	Low power mode	Low power sleep mode, effective at low levels
10	FAULT	Fault signal output	Output protection signal during overheating and overcurrent, low level effective
11	M1	Output channel 1	Output terminal, following IN1 signal, output amplitude is the power supply voltage value
12	M2	Output channel 2	Output terminal, following IN2 signal, output amplitude is the power supply voltage value
13	M3	Output channel 3	Output terminal, following IN3 signal, output amplitude is the power supply voltage value

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