Hi all, I was wondering if anyone could help me with a circuit design I'm finding quite complicated that I need for a little project of mine.
My aim is to build a motor to propell a levitating train around a magnetic track using the electromagnetic force generated via current carrying coils on the side of the track.
I want magnets on the side of the train to firstly be attracted and then repelled by the coils, which can be achieved through reversing the current when the magnets are at the mid point on the coils. This is explained on the diagram below.
I need a circuit so that the once the infrared beam is broken, the current in the coils is automatically switched for a certain period of time and then reverted back afterwards.
The currents I am using in the coils will be very large (in excess of 10A) so this may cause some concern. Also the switching of the current will need to be of around a few milliseconds so that the train does not come to a halt.
Any suggestions or ideas would be greatly appriciated, particularily circuit diagrams. Thanks for your time,
Pete
