36volt questions

I have a list of questions concerning 36 volt stuff.
The first one is to get some specs on a motor.
I have a 36/48 volt motor that came of a battery powered forklift.
I'm told it was the motor for the hydraulic pump.
I need some info on the motor and don't have much to work with.
It has a plate with a serial # and another #. Also 36/48 volt and Type 75AA is on it.
Does anyone know anything about these motors or where to get some info on them?

Furby, i have tinkered on a few golf carts in my day and they were always 36 volts. So if you have a place dealing in used carts around you might be able to stop and pick up some info. Sorry I am not more help. Are you going to use it on your mill?

I was thinking that the old Delco packs that accomanied the wind generators before the REA wired the contry side  , were set up for 36V .  Many antique appliances run 36V

No this has nothing to do with the mill.

I have a 36 volt motor from a cushman cart laying here as well and it's a different type of motor.

Furby,

Do you happen to know the make of the forklift?  I think a repair place for the forklift would be a good start.  You could also check with a industrial supply house too.

Furby,

Do you have a picture?

I can get one tomorrow. :)
Main things I'm looking for is correct hook up, amp draw, and how many horses it is.

Furby,

If you find out the volts & amps:

Amps X Volts = Watts

Watts / 746 = horsepower

These numbers work for DC and single phase AC. 3 phase requires a square root of 3 and a calculator.

Hope this helps.

Ok, here's a pic.
The left end is off it as it is cracked at one of the screws and I need to get it welded.



The other # on the tag is a part #.
The # is 8620080

Ok, let's move on to another question.
Anyone have any ideas of the best way to provide DC power at least 36 volts and high amps with a gas engine?
Wondering if any one had tried running several altenators at once to do so?
I need a back up power supply for when the batteries are too low to run the motor.

I've got a 400 amp generator that will charge them  ;D ;D ;D

  I used it for a drive motor in a Mazda pickup. Nobody I knew, in Arkansas, could build an electronic circuit to control the RPM's.  ::) ::)

I don't want to charge the batteries, I want to run directly of the generated power supply with a small storage battery in that system if needed.  The main battery bank will be totally seperate and on an isolated system.

  Then you want to run a higher voltage. Less amps

  I had two rows of Caboose batteries, that would be charged by a 2 cyl Onan and 100 amp generator. Also had regenerative braking. Just no electronic techs ???

  Most HP is required to get a vehicle up to speed. After that HP can drop way off to maintain that speed.

  You ARE wanting to power a vehicle, I presume ???  ::) ::)

How many volts can I push that motor to?

Fla._Deadheader


You would need to re-wind it.

I'm reading about folks pushing 72, 96 +.
They using different motors as they started at 36 and 48 volts?

Fla._Deadheader

 I'm not a motor expert. I BELIEVE the field windings are the voltage. I know 24 volts on a 12 V starter is OK, if used intermittently, not steady. Steady lets the smoke out.  ::) ::)

Gotta get the high temp smoke seals if you want to over load them motors ;D
