stoopid (on-topic) question about 120V generators and motors

it's too easy to not at least try, i think...

job one is gonna be stripping 15 years of orange housepaint off the entire thing. i expect this is gonna be great "occupational therapy." job two is putting some serious rake to it, chop-n-drop, an old-school rat-daddy dragster...track-only material. after the chassis' ready, mounting a scrounged motor to the cargo bed is a cinch. the axle already has a long flat for set-screws, so installing a sprocket or pulley ain't no thing. if it doesn't pan-out, we're not committed.

davo, it's the gears, yup...so this is like electric 2-stroke theory? ok, what kind of productive rpm's we talking about?

like, i know what the 24V/400W currey does...cool but not enuff for this job...120V/400W is faster, or stronger? both? neither?

this is gonna be a stout vehicle, something that'll handle some serious power.
 
400W is 400W. Expect some movement but don't expect to burn rubber. You might gear it down 10 to 1 (more or less), the motor might appreciate that. But it depends on the motor. Electric motors generally will have a very wide useful rpm range. But they don't like to run at very low rpm. So gearing it down will let the motor run at a higher rpm while you still get the torque you need as rubber meets the road.
 
400W is 400W.

s'what i thought. shoot...maybe 12mph with big reduction. nope, wouldn't be prudent.

but we still could wind up trying this someday on something suitable...if we do i'll dig this up and update...

thanks folks :cool:

EDIT: any gurus know if i can gain usable amperage by (dc-dc) converting to a lower voltage?

Your generator has an ac output and ac motors are lighter and very efficient. Why go dc?
 
that's why the subject-line sed "stoopid question"...i'm a total electric-idjut.

so bottom line is, with this particular generator powering a motor, it would barely be able to get out of it's own way.
 
yup...450W...as i mentioned, the currie's impressive, but it's still not enuff to slam a trike down the track.
 
Motor running generator running motor.... yes.... it is done right now in some hybrid vechiles.
Electric motors give maxium torque at take off then the fuel motor takes over and holds the speed. Excess power from the fuel motor can recharge the batterys as can regenerative braking.
The fuel motor is optomized for efficency at a certain RPM and load, the high power/torque times are when the electric motor comes in and helps out.
If they can do it in a car we can certainly do it for a bike or trike.

Forget the electricals,too much weight and too inefficient,this thing is prob.supplying 120V ,60 cycles and is governed to run at 3600 rpm.600 Watts is about 0.9HP so there is no power to waste.Is this a 2 stroke?.You could prob. get more power out of it at higher rpm.Any idea what the displacent of it is?
