Inside my full scale AC brushless motor

[zeropointbug]

Hey guys, just thought I would post some pics of the inside of one of the motors I have for electric car conversion. It's an AC induction machine, so obviously it's brushless... but the reason I opened it up is because I have to put different (sealed) bearing in it, rather than the open type that are in it (because they were oiled from a planetary gearbox built onto the motor).


Cheers!

I would love to put that in my Saturn...

I've been thinking about converting my daily driver over to EP for a while.

Holy crap! I'd hate to be the one to lift that rotor out... must weigh a ton.

I like shiny!


That is one huge bearing

I just checked out your project very cool. What are you using for a controller/inverter?
Any more info would be cool too.

How come all of the metal tools and the spray can and stuff arent sticking to the side of the giant magnet. I have to imagine that thing must have some serious pull.

[_paralyzed_]

could I put one in my E-Revo with an MMM on a kajillion S

What is the spliting maul for!!!

The magnetic pull can't be that great or how the hell would he have gotten the rotor out of the can in the first place? Still I would think the spray can would be attatched to it. IDK?

Is the core a permanent magnet, or is this an induction motor? I would think it's an induction type, which would explain the lack of attracting any ferrous metal within a city block!

Cool motor ZPB! Do you have any specs on it? Like kv, max rpm, max current/power, etc?

Those Siemens motors are built very nice. Siemens is one of my client and I asked them if they could make a compact, but very powerfull drive system and I'm still waiting for an answer. Good thing I have a few military clients who are in the industry . Just got to come up with the huge amount of $$$$ to get what I need done .

To open up the motor of course!

Not sure what model he has, but here is a spec of the 1PV5135WS14 model:

The inverter was the Siemens Simovert short (6SV-1) and here are the specs:

I also have a picture of the inside of the inverter and the manual if anyone would be interested in that.

Hey ZPB, Glad to see some progress on the full scale conversion. Have you had any more luck sourcing the controller? I remember that's where you were stuck when I last talked to you.
