Future Netgain offerings..

I had an interesting conversation with George Hamstra, President of Netgain the other day. He had seen our videos on YouTube and was pretty taken with them. So he shared some of their plans and they are pretty eminent. After asking him if I could share, he noted that they are taking advanced orders. He's got some good stuff going here and is understandably excited.

1. The biggie is called the 11HV. This is a version of their 11 inch motor that can handle much higher voltages. Nominally, 288 volts in a non-advanced setting and 336 volts with advance. Why the note on advance? Well the regen works of course in the neutral setting. Regen? Yes. It has Interpoles and will support regenerative braking.

I'm picturing a 288 kW motor and about 550 ft lbs. I waited for him to drop the other shoe and tell me about current limitations and total power limitations and all the other dream dashers.

NOT. In FACT, he starts talking about their own line of controllers. 1000 AMP controllers that talk to each other and you can string modularly for 2000 AMP or whatever. With PC like slots for option cards for regen, series/parallel switching, GPS, and a bunch of other stuff. Water cooled.

It seems they were the secret admirer that were going to purchase Zilla, and after what they thought was a done deal, Otmar backed out on it and it came apart. So they've engineered their own line of high power water cooled controllers. And 1K and 2K are just the beginning.

He did caution me they just weren't going to support 5K pots, it would all be Hall effect pedals. I told him we had looked at 5K pots early on, and decided it was the dumbest idea since the electric fireplace. So no loss.

He did mention they will feature a slightly higher RPM range, but I've forgotten what number he used. My sense is it was not AC induction type numbers of 9000-12000, but more like 6500-7500, somewhere in there. I just can't recall.

So we've kind of signed up for the advanced order list. I've got a "secret" project in mind if I can talk him into Siamesing a pair of these.

Apparently the IGBT thing has gotten a lot better recently, better silicon and lower prices, higher currents, easier drivers, etc.

This was about a month ago, and he was talking 10-12 weeks for the first motors. They actually put a video up on Youtube providing instructions for installing the controller, I just don't think anybody noticed. It was so simple, it wasn't very exciting.

Can't wait to see what you've got in mind Jack!

This got me to email Netgain to inquire about the details. I went ahead and ordered a WarP 11 "HV" to play with.

The WarP 11 HV as we know it internally is a high-voltage variation of an 11" motor. It has interpoles and should be able to handle 288 Volts in neutral timing, 336 in advanced. It is designed to hit 9000 RPMs.

The comm is a 57 bar mated to a 9" armature stack. This also allows for the high RPM and related HP (expected to be ~4 times a standard 11"). The 9" stack is also required due to the "height" of the field poles and interpoles.

4 variants of the motor:


  1. same as WarP 11 - 1.125" & .875"
  2. same as TransWarP 11 - 1.375" (32-involute) & 1.125"
  3. DE designed for direct input to Lenco transmission L=1.375" (32-involute), .9"D*.750" hole for pilot bearing
  4. heavy duty 1.750" & 1.750" keyed (either dual key or spline (27-involute) )
This got me to email Netgain to inquire about the details. I went ahead and ordered a WarP 11 "HV" to play with.
(1) How much are we talking here? $$?

(2) "4x HP of standard 11 inch"...what is the peak HP of a standard 11"?

(3) 9000rpm!:eek:

Thanks for the info!
Holy... :eek:. Sounds good. i may be about to chop my transmission tunnel out to make one of these fit! lol.

Good to see advances being made, controler sounds good too.

Will be hanging out to see more.
288 kW :eek::eek:

If this is true, a dual motor could handle 570kW :eek:

With some forced cooling probably even more

Hmm, hope that is not just a rumor :)

Maybe try one of these controllers with the new WarP 11 HV motor.

I will let you know. We are already on it.
Any other new motors besides the 11"?
9" and 9K RPM would be nice......

Eric

When will the Warp-11HV motor be on your website?

Any Warp-13-HVs coming out?

I wonder if the motor might be a modified Kostov?
Why would it be a modified Kostov? They make them for Netgain at the Warfield Electric Company in Frankfurt Illinois....

This is a Netgain designed modification to the 11 inch motor that Warfield actually manufactures. Warfield has always made the Netgain motors.

And yes, 288 volts, with 2000 amps from a Z2K would theoretically be 576 kW or 772 hp.

This represents a relatively huge leap in available power for conversions, and in fact I'm not quite sure what it means.

As Torque is a function of (kW * 9549)/rpm, a 288 kW power plant should deliver 1375 ft-lbs of torque at 2000 rpm. A Z2K, for whatever period you did achieve 2000 amps, would then produce 2750 ft lbs of torque, and we've just outrun the ability of any drive train I'm familiar with, short of the drive shaft on the USS Midway, to handle. We will soon be able to snap any drive shaft we connect to - instantly.

It's exciting alright. If my math does not bely me, it will reduce the drive train issue to how much power your batteries can deliver, and your transmission or differential can convert to motion without destruction.

So yes, I want two of them bolted together. Overkill is always appropriate in polite company...

We take delivery of a few of them in October hopefully. Since this is so new, we are not going to sell quite yet until we know more.
We want to check them out.
I am also having Jim Husted look into upgrades for 2 of them.


Any Warp-13-HVs coming out?
They are not even making the other variants of the Warp11 HV yet. They are just doing this initial version to see how demand is.
How the #3!! did I miss this thread! :D EV racing technology is just exploding all of a sudden! Awesome!

Now we have great controllers, the motors are in the pipeline... All we need now are some high current batteries that are bigger and cheaper than A123 cells

Stay tuned on the battery front. We have something in the works to make those high performance batteries affordable and available to the EV conversion community.

This is great news!

High Performance Controllers!

From what I gather, low-end torque is not something to worry about with electric motors...Its the "high-end" torque...

Jack you mentioned before that your 120V e-porsche can pull 540A (3C from your 180AH batteries) at freeway speeds of a bit over 4000rpm...

Which leads me to wanting maximum power curves...based on different HIGH-END voltages, not some wimpy 72V....

For example:

The new Netgain Warp-11HV
What are the maximum amps it can tolerate at each rpm?

Example:
336V
1000rpm = 2000A
2000rpm = 1000A
......
......
8000rpm = 600A
9000rpm = 500A (stated "redline")

I understand the concerns of the average DIYer but I am more interested in power density and discharge rate. If they're bigger and cheaper but won't let me suck as much juice out, as quickly, I would still want the A123s.

Same for me but it's not simple to make a battery pack out of thousands of cells. It would be much simpler if they would make some 20/40/60/100Ah cells with 50C continuous discharge so we could just connect them to series till we get the voltage we need.
The better question might be why not? :) It seems like it would be easier to modify an existing 11 inch motor that has interpoles, than to add interpoles to a motor that lacks them. I was just curious if anyone knew what the base motor was, or if they are making one from scratch.

If those rpm limits hold that would be truly awesome.
