Hello all, I need a speed controller to control the motor speed of my two DC gear motors. I am trying to get a consistent speed under different loads. The motors are 12 volts and 6 amps and they are coupled together. Here is the link

PM me a price and for more details.

Thanks

This is quite hard to achieve even with a closed loop control system. If one motor rotates a bit slowly it will load the other one and make more harm than good.

Why you connect the motors on the same axis?

so far its working great. One motor was moving a tab bit slower, so I coupled them and now they are both moving a the same rate. They are only on for 30 seconds at a time, so I think it will be fine.
