Beginner struggling to make motor rotate with ELEGOO Uno R3 and SimpleFOC Shield v3

[colapunch]

Hello SimpleFOC Community,

First of all, thank you very much for developing and maintaining such a wonderful project.

I have been studying the SimpleFOC library source code and experimenting with it for about 20 days, but unfortunately I have not been able to get my motor to rotate correctly.

My setup is:

• SimpleFOC Shield v3.2

• Motor: ipower motor gm4108

I purchased the SimpleFOC Shield v3.2 from AliExpress because it was out of stock in the official store.

I am a beginner in electronics and motor control, so I honestly do not know whether the problem is caused by my code, wiring, hardware setup, or my misunderstanding of the library.

I would greatly appreciate any advice or guidance. If there is any information missing, please let me know and I will provide it immediately.

Thank you very much for your time and assistance.

The code is shown below:

// Open loop motor control example

#include <SimpleFOC.h>

BLDCMotor motor = BLDCMotor(7);

BLDCDriver3PWM driver = BLDCDriver3PWM(6, 10, 5, 8);

float target_velocity = 2;

Commander command = Commander(Serial);

void doTarget(char* cmd) { command.scalar(&target_velocity, cmd); }

void doLimit(char* cmd) { command.scalar(&motor.voltage_limit, cmd); }

void setup() {

Serial.begin(115200);

SimpleFOCDebug::enable(&Serial);

driver.voltage_power_supply = 12;

driver.voltage_limit = 6;

if(!driver.init()){

Serial.println(“Driver init failed!”);

return;

}

motor.linkDriver(&driver);

motor.voltage_limit = 3; // [V]

motor.controller = MotionControlType::velocity_openloop;

if(!motor.init()){

Serial.println(“Motor init failed!”);

return;

}

command.add(‘T’, doTarget, “target velocity”);

command.add(‘L’, doLimit, “voltage limit”);

Serial.println(“Motor ready!”);

Serial.println(“Set target velocity [rad/s]”);

_delay(1000);

}

void loop() {

motor.move(target_velocity);

command.run();

}

The serial monitor output is shown below:

MOT: Init
MOT: Enable driver.
Motor ready!
Set target velocity [rad/s]

AFAIK you have to add motor.loopFOC(); in the main loop when you use the latest simpleFOC library

Maybe the example files aren’t up_to_date?
