Thanks JRP3. That what i was think about 10 degrees.

Thanks John.

I have tested it and it is not connected to earth. Direction wise the motor spins to the right direction. I have spun it from a 12v battery and could not see any difference how it spuns with either connection but there had no load on it. There is a reason /i think/ why they marked them with different letters. I am work on cars so have no specific knowledge on electric motors.

The one marked A will go directly to one of the brushes and the one marked F will go directly to the field, not sure why they bothered to mark them if the center point is not connected to the frame/earth of the motor.
But if it goes the right direction it doesn't matter which way you connect it.

There is my forklift motor. Could you give me some advice on do the bushes need to be advanced and if so how much? It will run on 120v. Also there are two connections on the case marked with A and F. Could you let me know how they connect as either way connected it spins at the same direction.
There are some pics.

Hi Franky.
Just out of interest what car are you converting and what are the dimensions of your motor?
I am approaching the same stage as you and am looking at hydraulic motor.
Regards John

Hi John.

The motor dimensions are 8"x11" and weights 66lb. Bought from ebay for £65 and is brand new. It seems be a bit under powered but cant find better localy or on ebay with delivery option.
I have no donor car jet. It will be something small up to golf/focus sized car generaly for commuting 10 miles a day. Currently focusing to get the parts to start the build of controller/charger.

Thanks Franky we are both in the same boat, I too am collecting and planning to build my own controller sort of based om Paul and Sabrina's controller.
I am electronics trained should be OK, I am currently experimenting with some electronics.

There's nothing much selling on ebay motor wise at the moment.

Realy in the same boat... I am waiting for the pcbs from Paul and Sabrina. I have everything else to build it.

Howdy folks! After spending part of the day yesterday at a small EV get-together, I'm fired up to work on my 97 Jetta I'm converting with two of my friends. We were poking around at motors, and this one came up:

http://www.ebay.com/itm/360454661776

There are no pics of the motor nameplate; but it appears to be a series wound Nikko motor with a brake on the back.

This auction is for a DC Electric motor # 3BA-17-33660 Good Used! AS-IS

Came off a 4000 lbs unit

s/n 0-51000-2220

2.5 KW

DC 36 volt Motor

11" long on case

16" over all length

8 " Case diameter !

With a Spline Shaft !

I thought that size-wise it sounded good, but a caution flag was thrown up by the fact that they're calling it 2.5 kW - I'm sure that's not nearly strong enough; only 3.3 hp?

Could one of you folks take a gander at it and let me know if I should (have) pulled the trigger, or if it really would be as underwhelming as I think it would be?

Thanks in advance!

HI All.

I was trawling the web and found this motor guide that looked like it might be helpful in looking for motors. Mostly because it lists power specs for many of them. One that grabbed my attention (with a bunch of similar part numbers) has a 30 minute cycle rating of 140hp(!). It's rated at 36V for 475A. Does that sound like it might be a useful motor for an EV? many of the part number are noted as clockwise pump motors, but for that power I'd make an adapter shaft.

For an EV, what kind of rated current should I be looking for? 2 or 3 amps aught to be fine, right? Just kidding, I'm guessing the higher ones like 185A are going to be the best bets, but what about the 120A options?

Hey vwd,

Do the math. 36V*475A = 17100W. 140hp Maybe a typo
