I have two ME1003 motors. I'd like to put them together and run them in parallel off my SPM72650 controller.
There is no double end shaft for the ME1003 motor, but I can access the shaft after taking off the rear cover plate. It's flush.
The front shaft is 7/8" diameter with 3/16" keyway. The internal thread on the crankshaft is 7/16"-20.
Motor diagram for reference: http://ep.yimg.com/ty/cdn/yhst-12939...003drawing.pdf
So, hypothetically, if I were to tap the rear shaft with the same thread type, would it be able to handle up to 60 ft-lbs of torque of the motor without destroying the threads? This is my last resort to couple the motor, but this seems to be the only way.
