New Crystalyte Motor series (HT35 / HS35 and HT24 / HS24)

... pretty much have the same issue (plus a few more things).

what other issues do you have? i guess i have solved most of them this way or another.

what gauge wires are people getting in the ht3525 i bought some 10awg and theres no chance of getting it in.
adam

12awg with heat shrink tube will fit in easily. just use the smallest size heat shrink (pre-shrunk) you can get, as the bigger the pre-shrunk diameter, the thicker it will be when shrunk. i did it here http://endless-sphere.com/forums/viewtopic.php?f=3&t=38848#p679207 with a 3540.

thanks for the reply, i think the 10awg wire i bought is more like 12 i will have to measure it to make sure, i might just buy some more.

Well the use of mushrooms instead of screws (should have been flat and flush with counter sinking)
The fact they use epoxy instead of locktight (should be able to remove the case without stripping mushroom screws)
Bearing not seeded flat, you can see the wobble on the gear side.
Side cover not flush can see oscillation.
Short wire length.

Axel quality is good, no complaints there.

just wait . Ive broken four of the axles on this motor, finally cooking windings on both my motors. but then again im hard on shit, i was only running a torque arm on one side for two of the failures, do not overtightent this axle, make some beef torque plates and youll be fine . max was happy to find me 5 axles (not exactly cheaply). im out of these motors now, and i wont miss them (bought probably 10 for me and friends). hated the wires/halls/etc issues

You must have been running high power and enjoying it enough to overcome that fact your axle would fail.
If there was any doubt in my mind over the quality of the axle I'd use the motor as a meat rotisserie or lazy suzan :lol:
Instead of underneath me at decent speed with the ability to fail.

My TA's are nice and snug, first time around I had a little rocking and it obviously got worse with time.
This go around I've go them so snug and secure that it's a pain to remove them

Need a quality mid sized hub, what brand did you move onto?

 

[MAGICPIE3FOCUSPOWER]

I have grind down the axle.
And fitted military 3x 12awg teflon with 5x1,16 mm FEP wires and as extra protection heatshrink for this cable harness.
Fit nice and easy I can remove cover without damaging cable harness.

Ps I have also installed hall sensors SS411a..

I had to laced all spokes head facing outside, due outside covers spokes holes are not countersunk....
Only inside spokes holes are countersunk.

do you have any pics of how you modded the axle.

[MAGICPIE3FOCUSPOWER]

Hmm too bad I didn't took pictures when modding.
But I have just use:

Dremel with miller drill bit.
High speed hand drill with normal HSSdrill bits.
Sandpaper.

Quite easy because the axle is not hard metal

adam

imho you don't need to mod the axle. it's easier to do if you lift the bearing from the axle a bit. that way you can enter the cables and then you press the bearing down. i even would re-think modding the axle. if you take away too much material you will loose strength.

 

[MAGICPIE3FOCUSPOWER]

Where can I buy the motorseal?

Thanks!

 

[MAGICPIE3FOCUSPOWER]

A new version of these motors are now equipped with hex cover screws?

 

[3nslav3]

yes indeed, the screws are VERY low quality and quarter of them need to get drilled out due to damage from the assy line if you want to open up the motor

 

[MAGICPIE3FOCUSPOWER]

Thanks I have luck looks much better and the spokes are drilled well.
I have also the older version with Philips screws, wuaaww that motor looks very cheap.
Spokes holes are drilled like with shaky hand drill...

 

[MAGICPIE3FOCUSPOWER]

Okay new version hex screws are a joke.
Those screws holes (where you insert the hex key) are not centered :lol:

And they are even worse as the old version screws >>> hard to remove.
Also these hex screws are not metric... :x

 

[3nslav3]

told you so they are utter garbage!

I've been thinking to drill out the holes and fit decent low profile M5 hexes (if M5 is possible at least) M6 will be to big
still have to take a look at it tho, I've only tried the removal on my spare HT3525 but since it is a spare motor I don't really care about it that much and it has been sitting in the box since April :lol:

 

[MAGICPIE3FOCUSPOWER]

It's quite simple to remove those stupid hex screws.
Just use a orx socket, which it's a little thicker then the hex screw hole.
Use a hammer and punch and now remove the screws 8)

But the Ht3525 can handle more amps then HS3540?

 

[3nslav3]

not sure about that, I think it's the same

all I've ridden so far is a HS3540 @ 60 amps with peaks of 80+

 

[MAGICPIE3FOCUSPOWER]

And what about torque at high speed?

I like to have torque and high speed...

 

[3nslav3]

with enough amps you'll get the torque you need out of a HS3540 with plenty of speed :lol: mine does power wheely's

but keep an eye on the temp tho, I wouldn't do this if there are a lot of hills, just for quick standing stops if you want to outrun kids on mopeds

 

[MAGICPIE3FOCUSPOWER]

Thanks!

What is your speed and voltage?

Yes I have ordered HS3540 but send me the HT3525

Also the axle is a new design, it's now a hollow axle instead of groove axle.
Looks like the shaving issue is solved now...

 

[3nslav3]

hs3540 @74V off the charger i get between 70 and 80km/h with a 26inch wheel

my HT3525 still has the groove axle

 

[MAGICPIE3FOCUSPOWER]

Hmmm so I have the latest version?

Also the motorseal cap is new, the motorseal now rotate around this cap instead around the wiring loom.
Your motor also has this new motorseal cap?

 

[MAGICPIE3FOCUSPOWER]

Also this bike is building for high range!

Battery will be 24S lifepo4 so a better choice will be HT3525?

 

[3nslav3]

yup for long range the HT should be better youll be riding more efficient

 

[MAGICPIE3FOCUSPOWER]

Thanks for your help! 8)

Yes I am riding now 48V HS3540 and the distance is about 45 km at 40 km/h.
So the HT should eat more distance at same speed?
While at low speed torque is more then HS motor?
