Motor Torque too Low

[Rahul Kajjam]

Hello,

I am experiencing an issue with my vehicle's motor. Currently, I am able to run the teleop code with no issues when the car is on a racecar stand. If I move the car to the ground, there is not enough torque for the motor to move the car forward or backward.

My guess is that the current limit is not set high enough on the VESC tool, so the motor cannot produce enough torque. I am using the VESC EDU that specifies a 25A continuous current delivery and 50A peak. However, due to the limitations of the motor controller, I receive overcurrent faults if I try raising the current above 32A. Does anyone have any insight into this?

Thank you,

Rahul Kajjam

Hello,

   so maybe that is the downside of EDU version. In theory, you could try using a battery with higher voltage (i.e., more cells) as it should reduce the current. Otherwise you can tune the internal PID settings (along with the ramp) to lower the acceleration.

Best,

J.
