I have find a 11" motor you can see bellow. With his large brush, the 48 bobine in the rotor (same than ADC 9") and his armature of 5.75 in lenght it is very similar to Warp 11. Do you think it's a good motor at low cost to replace a Warp 11?

So now I need to run it at hight voltage (120-150v). Probably advanced the brush by 10 degree to realign the flux will work.
But what do you think about variable advance of the brush. Something like at 40v and low amperage the brush is set a 3 degree and when you snap the pedale to the floor the brush come at 10 degree. Maybe the brush holder can be variable from the accelerator pedale!
Do you think it's a great advantage compare to a fix advance of the brush?


Also, in the case of this idea isn't good is it possible to add interpole to a standard motor to help it to run at higher voltage?


Thanks









Variable brush holder.....

Greetings from Ireland. Im new to this so forgive my ignorance. I recently received an ADC 203-06-4001A. The label on the motor said it is rated at 72-96V, however my invoice says the motor is rated at 72-144V.

We are having problems with the guys we bought it from (well known company) because of this issue.

All I want to know is, will this motor be ok to run at 120V?

I am currently running 120volts 800amp controller.

I have been in contact with Kostov and they recon the old KFG-14402 motor‏ will probably not handle the high current.

They recomend 750amps peak and below 4000rpm at 192volts. 180A 4000rpm constant

Anyone have any experience or know of a simular setup?

Not sure if my if it would be a great advantage in swapping my 9" adc motor for this kostov motor to run a 192volt 1200amp controller

are just iron bent into series of 90* ears. Very poor description,
but you have seen them. Why are they not built more in the shape
of a propeller or a house fan blade. My motor has been sealed
but I'm about to open it up for more circulation and I guess I'll
see if it gets much air pushed through the motor with the
standard design.
Anyway the standard fans don't look like a design to force a
lot of air through the motor, why the design?

Did someone use Manzanita charger for break in new motor?
Voltage should be possible to decrease to 12V and amp limit can also be set.

Would 12V Battery parallel to motor present more acceptable load to the charger?

Any experience?

First one is a 6.7 inch Prestolite. Major looked at some photos a while back and has given me the idea that this is a tough motor (It REALLY is). It was rated at 24 volts by the rebuilder, I have been pulling with it for a couple of years at 48 volts and doing well. Now for the last pull of the year I want to see what happens/breaks at 72 volts, the max my controller will handle. Will this motor need any advance when going to 72 volts? If so how much.

The second motor is a GE 13 inch that we will be trying out for the first time next weekend. I've stripped out the 72 volt batteries and controller from my old ultralight and installed it in the new one for it's first tryout. This is a newly overhauled motor that we have set up with adjustable brush rigging. It will move up to 10 degrees in either direction. We plan on a final voltage of plus 300 and plus 1000 amps once we can afford the batteries and we get the controller built.

Any help or advice would be appriciated. ]]> Electric Motors Jimdear2 http://www.diyelectriccar.com/forums/showthread.php?t=48977 http://www.diyelectriccar.com/forums/showthread.php?t=48959&goto=newpost Sun, 29 Aug 2010 01:33:45 GMT Emerson 40hp 3 phase AC Motor. 1800 Rpm, 230/460 60 hertz.

if i take a forklift motor, with mnay bars, and advanced, lets say to take higher voltage, what could it handle. ie: putting a 48v motor to work with 200v DC or around 144-200v dc would something break very quickly, or work inefficiently.

I didn't find anything about them on here already, does anyone know how these would compare to the usual Warp 9 and similar?

80kw is closer to the peak power rating I'm looking for, torque is good, continuous power is 40kw which is good, regen capable etc. and the price isn't that crazy.

Is this the entry level AC (BLDC is similar to a 3 phase AC motor if I'm not mistaken, but with 2 phases driven at a time with dc) motor combo that we've been waiting for???

I do not care about the Robot News, All I care about is the Specs or lack of them.

Can anyone determine what they are really capable of like this one>

Here is the deal I want to find a DC wound motor made for a EX-GO 12 spline Axel. I want acceleration tree climbing torque to get off the starting line, but some RPM to get 30 MPH or better.

Better yet I want bragging rights in my gated golf golf cart 1/8 mile drag races we have on Memorial Day, Labor Day, and end of year holidays. All for bragging rights.

Thought I had it all figured out using a GE 282 Raptor motor, with 500 amp controller. Blew everyone off th line with a wheelie, tire barking, and top 30 MPH speed in 30 feet.

This this jerk pulls up in a standard factory cart made by EVE called a Farplay. Please take a look at it the specs are awesome,

He is really a nice guy and blew my doors off. It is actually a NEV made for golf communities. This thing has all the Bells and Whistles of a real car like bucket seats, built in ice chest, and trunk, lights, horn, turn signals. independent suspension, 4-wheel disc brakes, and looks really nice.

Mine is all stripped down to race, right down to 4 lightweight batteries. I blow him off the line, but half up the track he pulls up to me, slows down, and offers me a beer. Then leaves me behind in a cloud of dust wating at the finish line drinking beer..

After many bears and looking under the hood, the only mod he claims to have made is program the controller lifting th 35 MPH limit which gets him 40 MPH.

Guys only thing I see he has under the hood is a AC motor, decent controller/inverter, and 4 Trojan AGM batteries. The pisser is it is factory stock, cost $8000. I go that much tied up in my buggie.

How can I beat this guy? Just join hi and buy one then tinker with to get that extra mph or 2 on the top end?

I've updated my 06 Zap PK from 72 to 132 volts. The car runs much better but the motor gets much hotter. Right now I have a blow through fan for cooling. In addition to this I would like to add possibly water cooling. If I wrapped the motor in a sheet of copper braised to copper tubing then used a pump and a small radiator - I have an oil cooler radiator that would be perfect for this. Would this work - meaning would cooling the outside of the motor help cool the motor as a whole? The fan cools the inside of the motor. I did a search but could not find out anything.

On a related note - if the above works would it be possible to also have the same system heat the batteries in winter? I'm looking to drive this year round and I'm thinking of wrapping the batteries in copper tube and when plugged in using a water heater element and when on the road using the heated fluid from the motor cooling.

Last question - what is a safe temperature for a motor? What temperature would I want to have the system turn on at? The reason I ask is the oil coolers from a mazda rx7 have a built in thermostat set at 180 degrees. Below this it bypasses the oil cooler.

I know lots of questions - I'd appreciate any help you folks could give.

I need to have my gokart motor rewound. It is a compound motor, it
has overheated the field the coils on one end, nearest the brushes.
Since I'm so much smarter now :-) I would
put a screen over the brush area rather than the solid band.
When I rewind the motor I think I would mill out four air holes
in the coverplate on the shaft end where the fan is and
screen the brush cover for more air circulation.
Any feedback on that?

First, is it wise to change my motor from compound to series wound?

I use a NPX4834 controller made for a series motor. I did have a variable
resistor to adjust the current through the shunt field, but I never noticed
any difference by adjusting it so we just ignored it.
It is a four pole motor, two series, two shunt, four brushes, my
thought is to wind all four as series fields.

Should I wire all four in series?
Or should I parallel the two new ones with the originals?
How do adjust turns count with these two options?
And should they be N, S, N, S?

If you want data on the motor I'll be happy to provide it.
I don't have turns count. 56 copper bars on the commutator.
