Motor control circut
Klaus,
Sorry about the confusion, I guess I have been working on this project so long, it's starting to fog my mind.
This is a totally new and different kind of dc motor. The armiture or rotor has no windings on it what so ever. The motor has no communtator & brushes. The coils are used as field coils and totally power the motor. At present, I am powering the coils on/off by using a set of motorcycle points (open/close). A small cam on the shaft of the motor operates the points.
Now, I would like to replace the motorcycle points with electronic switching. I have built a small disk that is mounted on the motor shaft, this disk will have two notches cut into it that the opto sencer will sence. When the opto sencer trigers on/off it will also triger the mosfet on/off to power the coils. The coils will need to be powered two times per rev of the motor.
The diagram I included with this post was located on the web, it is being used to operate another dc motor(ADAM's Motor) that is similer to mine.
However my motor uses a totally different type of coils. The amp load is different. An there was no parts list or discription included with this drawing.
I just need to know the voltage the mosfet needs at the gate to open it up and how do I get there from 36 vdc power. Also need to know exactly how to hook up the opto sencer.
Hope this helps, Thanks for your help. Later,,,Jack
I am totally NEW at electronics
