H-Bridge

cocolat1x

Hey, i need to make an H-Bridge, maximum 24 V, that delivers 70-100 amps for about 1 minute maximum to drive 2 Maxon motors. I plan to modify the maxons so the will take more than their 70 amps, thats why i want the bridge to approach 100 amps. Any good tutorials where i can get starting on working on something like that?

A good place to start is with the OSMC group on yahoo:

There are designs for an open source motor controller that should meet your needs.

Do you need speed control or just ON-OFF control ?
If all you need is directional ON-OFF, consider using relays.

If using speed control, how do you plan to control it, PWM, Servo signal, potentiometer ?
