I have built what amounts to a go kart using an inverter and a treadmill motor and controler the acceleration time on the controller is not adjustable. I have a solid electro mechanical background but once a component has more than two legs I get lost. The motor is about 2 1/2 hp and uses an MC-60 controller. it runs okay but the lag in acceleration and deceleration makes everything difficult. especially throttling back and putting on the brakes. On better motor controllers there is a pot or variable resistor to change the acceleration. I assume that there is a fixed resistor that can either be removed or replaced with a different value and get instant voltage change.

Does anyone have experience with this and can help me?

On the MC-60 R19 can be removed to defeat having to take the pot to zero to start.
I have managed to defeat the accel decel time, you may be better looking at a KB controller for complete control.

I am having trouble finding R19, lots of others are numbered but not 19 it seems. how did you defeat the acc/dec delay?

 

R 37 looks like it was clipped at the factory, standing on one leg

 

If you search here I have previously posted reverse engineered drawings of the MC-60.
Some of the resistors are tailored for different motor etc. And removed or cur as needed.

thank you max. I will search mc 60

 

I think I found the right schematics but they are beyond my ability to understand.
