I guess I'm asking - is this setup capable of doing the job (moving a person on a mostly flat track) and where is the weak point? Would a servo motor be better? the driver? arduino code? I'm out of ideas and money and desperate to get this 2 year project operational. I had help with the code and the setup but the person who did that is out of answers, and I have no idea at all. I measured the amps at failure and it peaked at under 2amps before the motor stops. I tried an alternative (48V /40C no difference) We've tried every stetting on the driver, and the power source (2 x dewalt 20Vmax 9Ah in series ( seemed capable of delivering enough charge.
The steppers are each rated at 3nM, so I figured I should have enough torque - except I can stop the wheel with my fingers. So I moved to 2 x stepper motors (geared down 2:1) with arduino UNO control. I started with eskate world (BLDC/VESC) but could not get the low RPM (<600rpm) with any precision control. I need to power a person along a track, on 4x 90mm skateboard wheels.
I have a specific project that has brought me here, on my knees, looking for help. I am an artist and I have no electronics skills, at all.
