Re: Reversing motors electrically?
Here's how the "H" in H-bridge gets its name (see thumbnail) - there are actually 4 switches, two used for forward and the other two for reverse, which make an "H" configuration with the load (in this case the motor) in the middle. Normally when the motor is off, all four switches are open, but if the braking function is used then the top two switches are open and the bottom two are closed, providing the short (please correct me if I'm wrong here, Al).
