...then why not for motorbikes? We're now on WhatsApp. Click to join. Shelke knew that vehicles running on fossil fuels were 30 to 37 percent fuel efficient. With the future belonging to electric vehicles, Shelke decided that he would build an electric motorcycle but there was a serious problem. “The electric vehicle is a very efficient but storage of energy is the problem. The capacity of battery where battery is stored is the limitation.” The next problem that Shelke faced was the distance covered by the electric motorbike. “If the capacity of energy storage is less then the distance an electric motorike will go will also be less. This meant that the electric motorbike I design would be sufficient for city use only. Generally a person in a city wi...

I have a board with a MC9S08DZ128CLH and CodeWarrior firmware that does PID control with a servo. It uses a 0-5 volt potentiometer feedback for position control of an actuator (servo) with a potentiometer. I want to switch to using a stepper motor control and stepper motor position as a 0-5 volt position signal. I believe the attached PDF document describes what I need in detail. I tried using the Leadshine DM805-AI from automationdirect.com. It worked with some limitations. I developed a "limit" circuit to limit the travel of the stepper so as not to damage the position sensing pot if I needed more than a 1 turn pot, which I often do. The stepper had to be prevented from taking the pot beyond its limit of turns. Another downside of this solution is ...
