I would say he needs a caterpillar diesel and transmission out of a D8!

Maybe he is building a hot rod or something and doesn't care what brand it is? Maybe he is just keeping his options open to find the best deal or something unique?

THIS is a "big motor"

 

[Rice Nuker]

What the heck is that? Are the motors or generators?

Heres one ready for install.Those are little motors 273.This is more like it.

Put that in a vega, hahaha:wack:

Or put a vega in it!

Man, I think that flywheel is as big as my house...LOL

Actually a motor can be a generator can be a motor can be a generator

That is why older generator systems HAD to have what is called a "cut out relay."

Really old systems, before regulators came along, were a single cutout relay in a can. Regulators included the regulator. Automotive generators are not "self limiting" so they must also have a current regulator, hence the three relays in a generator type regulator ---- voltage regulator, current limiter, and cutout relay

Now the REASON you need a cutout is, that if the generator stops charging due to a problem, or is shut down, OR breaks a belt, it tries to become a MOTOR, and I, in fact have had that happen a couple of times in my "yute." If you break a belt with the engine running, the cutout doesn't trip, and the generator sits there spinning wildly, until you either disconnect one of the regulator connections, or wedge a tree branch, etc, against the pulley.

Ow! Looking at that makes my head hurt.

Hey Del,
Speaking of big engines, here was my wife's engine(s) when she was CHENG of The Gridley. 4-General Electric LM2500's @ combined 100,000 SHP, 75MW

My 273 car is still faster though.

 

[67Dart273]

I'm pretty much a "fish out of water." I was in the Navy for 6 years, maintained GCA RADAR and other air NAVAIDS at NAS Miramar. I was just "lucky." Was never on a commissioned ship at sea.

Wonder how fast that thing will really really go?

huh?

 

[Rice Nuker]

Roger that!
When I was a kid, I used permanent magnet motors as generators on little 4th grade science projects and such.
My friend claimed they stuck a car battery directly to a generator on some old car and cranked the motor over. Dunno 'bout that.

This thread is getting pretty cool.

What/where is the starter for that monster, and what is it for??

[67Dart273]

Some engines had "starter generators." These are typically on small engines, like some older garden tractors. I had an IHC "Cub Cadet" garden tractor for a little while, and it had a starter generator. In reality they simply have a starter solenoid which applies battery power to the armature, IE bypassing the cutout.

When I got it, the cutout relay in the regulator was bad, so I merely replaced it with a diode

The cub:

Tearing the bad cutout relay apart

I actually used a bridge rectifier because RadShack didn't have a diode I figgerrrrrd was large enough. The way this bridge is used here, two of the 4 diodes in the package are in parallel for more current

Wiring for a similar rig. No. 43 is the starter switch, and as you can see, it simply applies battery power to the armature of the generator, turning it into a motor
