Hello,
I'm an avid reader but this is my first post. I am building an electromagnetic brake assembly on a motorcycle. The machining is going well but I have run into a circuit problem that I need help with, please.
The brake is 24v powered through a 12 to 24 step-up. After doing research in the archives and reading the FAQ I learned that the electromagnet may create inductive "kickbacks" that might damage my switching equipment. First question: Am I on track, is this an issue of concern?
So then I read about "commutating diodes" in a inductor commutating circuit at http://www.allaboutcircuits.com/vol_3/chpt_3/8.html. I'm not an electrical engineer but I found the the material very informative in a general sort of way.
But it led me to question 2: What type and size of commutating diode do I need and then where do I go to buy one?
In the attached rough circuit diagram there are two batteries with a cut-out relay assure one battery is always available for starting the engine.
Thank you in advance,
Coach
