    Brushless DC & AC Induction motors > 15 HP

    What about taking a Mars PMAC for each driven wheel? No differential necessary then. Rated power would be 2 x 4.5 kW = 9 kW = 12 hp (with solid potential to tease out more).

    3-Phase AC Motor Control ???

    Frank, you don't need a midpoint connection since there's no need to hook up the machine's star point (if it has one at all). Even more - it might hurt since a fixed star point cuts off some percentage of the achievable output voltage. Think of the three phase voltage system as a regular "Y"...

    BLDC Motor and Controller - How to match them?

    Thanks, guys. Looks like the KBL72301 would be the right choice for me - unless ... I read you fried it twice, drewjet. :evil: Paying 600 bucks just for sending controllers forth and back doesn't look like a perfect deal. Any news on cause study?

    BLDC Motor and Controller - How to match them?

    That's exactly my concern as for making a controller decision. Am I right assuming that you own a Kelly KBL72301? And still not melting down or dismantling the Mars? What battery voltage/current can you reckon as "save" operating point (certainly not wanting to hold you liable)? And what would...

    BLDC Motor and Controller - How to match them?

    Thanks, fechter. I guess then, the only non-confusing way of rating BLDC motors would be to refer to the DC side as well ... If this applies to the Mars PMAC then a Kelly KBL48201 (48 Volts / 120 Amps continuous) would be the right choice, I guess. :?:

    BLDC Motor and Controller - How to match them?

    Hi everyone, being a first time poster at endless-sphere (after reading for a while) I have to say I'm very impressed what seems to be achievable if you're willing to lift your butt and get your hands dirty. You guys have some really neat projects going and I'm glad that you're willing to share...
