Building a Motor Controller Tutorial

[imginit]

I'm looking to build a 3-phase motor controller. Are there any good tutorials to get started? I saw a great one on instructables.com; however, it was for a single phase controller.

It's a pretty complicated thing to design one. I highly recommend simply reading all the custom-controller threads here on ES, starting with Arlo1's, Lebowski's, etc. Most poeple start and quickly give up, though. It's a LOT of reading; there is no "tutorial" that will just walk you thru it. THere is a whole lotta stuff to learn first.

BTW, the first thing you can do is learn how the brushed controllers work, and how to make those work well. All of that will help you do the more complicated ones too.

I don't know how to build a controller, but...if I wanted to learn, don't learn the old way. This is the controller I'd make, the Lebowski:

Hiya. This one on the Instructables site maybe?:

Note one comment there:

Very poor choice with a 3 phase motor. If the grounds short the bike can kill you.
