I need to know what the best way would be to go about using 2 motors to turn a single shaft - basically like a lathe where at least one side can be moved back/forth along the turning axis as well as allowing one side to slow down (user controlled) and then come back up to the synchronized speed.
The shaft will need to turn from 5-100 rpm and the weight of the shaft (each end mounted on 2 bearings - 4 total) and material will be from 4 - 25 lbs - but probably 6-12lbs on average.
IDK if a direct drive setup could be used where the motor is attached directly to the shaft or an alternative could be chain or belt driven. If belt driven, a spring tensioner could be used when the one side needs to be slowed temporarily.
What I most need to know is if motors can be this accurate as to synchronize, maybe by using the same power source feeding both motors but IDK if minuet differences in the motors would make them turn at slightly different speeds?
Assuming that 2 identical motors are used, what type of motor would be best suited for this application? As for the power supply, what would I need to look for, something like a PWM or a simple DC drive controller?
