Hello! I am currently designing a cup that will hopefully counteract hand tremors which could be used by people with Parkinson’s and essential tremors. The idea is that a motor in the handle uses data from an IMU to make rapid, small rotations on a shaft connected to the cup to stabilize it. It’s kind of the same idea as a camera gimbal, just on a smaller scale. The BLDC gimbal motor seemed like the best motor for the job since, when used with an encoder, has accurate positioning, and has speed control, pretty much instant acceleration, and is quiet. However, my question is, what voltage should I be supplying to the Sparkfun TMC6300 driver (which I am using to drive it)? I saw on the guide that 5V from the red board was sufficient at low speeds and no load, but unfortunately, I am running it at high speeds, and with a load, although there is bearing in front of the motor that holds the actual weight of the cup, so the load is the rotation of the weight of the cup. Thanks for the help in advance!
The usable power range for that pairing is very low (the motor limits the drive voltage; the driver limits the current) because it is meant for smart knob designs and such
For something like you’re describing you’ll probably want to look at the more common higher-power BLDC motors & drivers from other vendors (we only sell the ones you’ve mentioned)
