7kW DC Motor. Make good use of it?

[Dani]

Hi guys,

I have a 7kW DC motor lying around and I don't know what to do with it. It was a CNC drive or something similar, once.

Regarding the motor:
It has two modes, which read:

S1:
152 V / 33,2 A / 4500 W / 3000 rpm (without fan)

S2:
155 V / 51 A / 7000 W / 3000 rpm (with fan "10 l/sec" of air?)

The blue thing in the trunk is the fan it needs to run at 7kW. Without it's "only" 4,5kW. This thing is pretty heavy, I made a note: ~25kg. I guess it's full of copper and all of that awesome stuff. Sadly I threw away the 380V AC to DC converter unit. Damn.. it has a sensor for RPM. When opened there is a small lable with "ABB" in bold letters and some text:

Code FC12T R0001
No. 514540 R09/05
Ke: 6mV/rpm

Ke is part of the rpm sensor.

Please correct me if I'm wrong: 3000 rpm at 151V equals ~20 KV? So if I plugged this to 12V this should run at ~240 rpm?

If I can run this thing off a battery charger or 12V PSU I'll be able to make it spin. But what could I do with it? A lathe? A bad-ass-drill? Surely no ebike.

Electric motorcycle, or small electric car? Like an old Fiat 500/Fiat 126 or similar.

I forgot: I live in germany, no sense in building anything that moves on a road. Too many laws etc

Electric boat?

Electric boat?

no. No helicopter, jetski, hovercraft or anything that moves outside my garage.

There is a good bit of myth around the EMV stuff in Germany. It shouldn't be necessary: http://www.elektro-auto-umbau.de/
("engine" change instead of new car build). Don't be disheartened and have a chat with the TÜV etc. .
