In the electric gokart project that my son and I are doing, I don't
have the regen potentiometer from the lectra, just the swingarm with
motor, drive chain, controller etc... I also have the PDU board, but
wasn't planning on using it for the project. Can I just ignore the
Regen braking and leave the input resistance to the controller open,
or do I need to hard wire a set resistance into the controller to fool
the controller that regen braking is not active?
Sorry, I can't remember. Try it both ways; it should; not hurt anything electronically.
I also want to wire the throttle through a switch/resistor network
(to give me some top speed control - I don't want my son to get hurt)
and into the controller, but need to understand the throttle circuit a
little better to determine how to alter the throttle signal to limit
top speed. Is there somewhere I can get an owner's manual for the
controller to make sure that I don't do any damage with the throttle
or regen braking alterations or was the controller developed
specifically for EMB and no manual exists?
The Throttle control limits torque, not speed. So you would be limiting torque, not speed. The motor is internally limited to 13,000 RPM to prevent the motor damage.
