PWM dc motor controller with current limiter

This is a version with current limiter, the bd435 transitor pull gate on fet down, and motor current fors down. You must adjust the resistors to fit your motor current.

This is another version where the current limiter is inactive, and turn on a LED. It Will then be possible to makeup sure that i run the e-bicycke in a low energi consumption mode, so I can drive more km on a charge.

You can also ad more n-fets for better stability and less watt/heat loss in the fets rON stage

  1. Do you know current limit feedback using a comparator?
