I’m very new here and have just acquired an Odrive 3.6, two D6374 motors, and two AMT10E2 encoders.
My first question is how close can I mount these two motors to each other? My first attempt was fastened to a 1/4" thick aluminum plate with the motors’ shafts sitting about 7 cm apart, one above the other, both pointing is the same direction.
When I manually or through the Odrive turn one of the motors the other motor will rock, so there is some magnetic coupling.
I’ve removed the motors and mounted them to a test rail for calibration, but how close can these motors be mounted together and not cause interference?
I have some tight space constraints. This is for an experiment for control loading a high-torque, two-axis hand controller.
There may be some slight magnetic coupling, but with a high resolution encoder like the AMT10E2 and with well tuned feedback control, it shouldn’t be a problem I think.
Thank you. I was suspecting that the proximity was causing my motor errors, but even with the two motors about 20 cm apart I was still getting motor errors:
