I have a static torque control application that I am hoping to implement with a VESC and a permanent magnet brushless motor with Hall sensors.
It would be a subsystem in a control loop that would continuously adjust the torque applied to a torsional spring.
Most of the time the torque would be constant, so the motor would not be rotating. Both positive and negative torque would be needed.
Is this even possible to do? If so, how would I set up the VESC?
If it is not possible with a permanent magnet motor, how about an induction motor?
I have used VESC for other applications, so I have some experience in setting one up.
I am in no way an expert, I am not even experienced. I am having the same issue - but I just noticed this video: https://www.youtube.com/watch?v=H-6qzmeCNtw
- Full torque at zero speed.
So I'd say this answers your question: it should be possible.
It should be pretty easy. The torque is proportional to the active current applied.
There are a current control foc mode.
Buy the way. It's rather easy to configure trough aux, ppm or serial port input.
Thanks for the replies.
I have torque control set up now using duty cycle FOC and pwm input. It is working quite nicely.
At first I was surprised that the current drawn from the battery was so small, but it made sense after I thought about it.
