Can you estimate what the total price would be for the small motor shipped to the US?

What is the kv of the small motor?

Small motor is about 60kV for this version. The new versions are 45kv but we will not have stock until May.
Shipping to USA for 4kg packed is around 55€

Have you tested power of the 60mm motor for shorter periods, but not power bursts (e.g., 1 minute)?

yes, here you will find some curves doing bursts and hold power test.
The shape of the power test does not represent the maximum power at low rpm as our test setup does a smooth ramp of both power and load.

All test were performed on 60V battery with a kelly controller.
Maximum power was limited by the controller and on other tests we reached 8.5kw mechanical output.

Hey Adam :)
i guess you are quite busy atm, cause of the realease of the lmx64 and the delay.

Could you please tell us the changes of the 30mm motor beside the 45kv change?
* still capable for about 180amps phasecurrent burst?
* 0.35 lamination now? (like the 60mm)
* expected efficiency?
* when in May are we able to order them and will the price be the same?

with kind regards
Alex

Yes 180A phase burst possible, they have much thicker phase wire than the ones we got before. High phase for a few minutes will overheat the motor. It is equipped with KTY84 temp sensor.
0.35mm lamainations on the stator
The efficiency i dont know, similar to our motors for the 161 I guess at around 88% if I remember well.
Available from 5th of May, the price will be higher than the older small motors we still have in stock.

thx for the information Adam.

thought with lower kv the pase wires should be thiner cause of higer turns and due to higer resistance in the thinner wires, lower pase-amps could be appliable. maybe i am wrong^^
but in fact heat should not be the issue cause were producing a custom motor housing with enough surface.

5. May sounds good :)

My motor arrived safely today. i can't believe shipping was so fast to the US.

This motor is beautiful! Powder coat/paint looks great and it has quality bearings in it. It looks so much nicer than its ali-express cousin. With the sprocket included its a great deal.

Thanks for offering these for sale! Its nice that as a full bike manufacturer you haven't forgotten about us diy guys.

Is the 6-pin hall sensor mating connector a proprietary kelly item or is it something I can buy from an electrical supply place online?

hey Adam,
after 1000km (at rough mountain terrain) were really happy with with our 30mm motors, besides the heat problems, due to the quite high power we have to send in over long time. (climbing up steep roads for 1000-2000m in hight)
We produced custom housings and immersed the motor 1/3 with oil. Now were doing 3.5- 4kw cont. and 6.5kw max atm, but were looking for further improvements, so is there an upgrade coming out for 2020 (30mm motors)?

what would you think about customised halved QS3000W(140mm), QS2000W(120mm) mid drive motors? these are some sort of ipm- design and behave really good with fw and generally the nucular12f. Theyre also marvellous in the efficiency if you can believe the datasheet (with belt reduction)

Zeurus,

I don't want to derail the sale thread but I would love to see your work on that 30mm motor as well as some more specifics about power and heat you experienced. You do amazing work based on what I saw on that link in your signature.

I'm super happy with the 30mm motor I bought from this sale. I figured I'd have to stop at 3-4kw peaks. The power levels you are talking about here would make this my ideal motor for all my bikes.

Do you have a build thread featuring your experience with this lmx motor?

4kw output is really pushing it on the 30mm, it depends on what you call "peak"
From my dyno testing the 30mm can not really output more than 4kw for a few seconds before temperature gets too high.
The latest stock of 30mm have 0.35mm laminations and thicker phases, also a KTY 84 sensor integrated.
Those are the ones we are selling now. We had a few samples with 0.5mm laminations and thin phases that were sold before, this is what you had Zeurus.

By the way, we also have samples of the 30mm with IPM design, but we did not had time to do comparative testing on the dyno.

DanGT86: i made a thread with our new bikes now, if you wanna see details. Temperature depends on a view factors, but you definitely need modifications if you want more power out from it.

Adam: with 6kw it takes about 20secs till we reach 100degree, depending on outside temp(with our modification). and we do have the new 2019modell with temp sensor and 0.35mm laminations.
sounds good! tell us, when you have tested them :)

Hi Adam,
I'm interested in ordering one of your motors, but I still have to decide between the two.
Could you please post the complete specs for the 60mm so it will be easier to compare.
Last thing, I remember vaguely from an old post that your motors' windings were 18Slots 16Poles, is this correct?
Thanks!
P.S. I am mostly interested in the Kv and the no-load current.
Do you have a drawing for the 30mm? I suppose only the width is different from the 60mm.

Hi Adam,

do you think it would be (with reasonable effort, so not using a hydrauclic press to push out a bearing or something...) possible to open the motor and put hall sensors closer to the rotor, so that it can be used with a Kelly KLS?

Thanks!

Yes it could be done, no need of special tools if you install the sensor on the back side of the motor.
We never tried for lack of time to do it properly.

Hello Adam
Can you tell me if the 60mm is available as IPM motor to suit a sine wave controller? Do you have a more detailed drawing to what is on your website? I'm interested in this motor as IPM. Any idea if stator can be liquid cooled easily?
If not IPM what controller would you recommend?
Thanks

Cheers
Tyler

Also, if anybody wants to respond, this motor looks slot like Lightningrods' big block, same bolt patters, size etc. Can someone confirm they aren't the same item? LR big block coming in IPM of course, which was my question to Adam.

Thanks

Cheers
Tyler

Hello, ours are SPM. IPM versions are also available but we do not stock them and MOQ is 100 pcs.

Hi Adam,

Is this 60mm version usable on a go-kart? I have a Kombi Kart around 80kg + 95kg myself equipped with a Honda GX200 slightly tuned to 8.6hp.
