Re: [PSUBS-MAILIST] Pulse/Stepping Motors

Excellent description of operation. Thank you.

I am building a miniture (6' long) radio-controlled model sub and
purchased a stepping motor thinking it would give me some good speed
control however, I think I purchased the wrong kind of motor now. Not
sure what to do with it.

Thanks for the tutorial. It is a big help.
