Thx for your explanations, @Owen_Williams. I just bought small 2112 gimbal motor with ~20ohm resistance. And this motor act like the previous one. L6234 doesnt heats anymore, but motor still dont turn and makes squeaky noise. When i put power on arduino, motor turns to the left, then to the right, and after this it starts to make squeaky noise. When i put some velosity values, noise changes a bit. First i thought that my power supply can be a problem. I just use 19V power supply from laptop with DC/DC stepdown LX9006. But nothing changed when i switched it on 18650 battery with 4V. I tried to change PI, ramp\_voltage values in code, but it didnt help. Maybe this squeaky noise comes from high/low PWM frequency? But i cant find any values in code to change it. --- _[View the full topic](https://community.simplefoc.com/t/a2212-13t-bldc-motor-and-problems/74)._
