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

On my HT, the windings touch the metal base at certain places juust like in the pictures, does this mean that it could short or make the whole bike live with voltage and current??? (since the metal base is in contact with the axle and therefore the whole bike)
 
At one of my motors I also heard a `sliding noise` on the inside of the motor when spinning arround, ( windings touch the cover ) I couldn´t get it away so I did hit the motor shaft on the grond ( not to hard ) so the motor is horizontal and it hits the floor with the shaft, with the cover above with the sliding noise.

So the stator was moving a bit more to the middle I guess. it is a cheap solution and this problem should not happen but the problem was gone and the bike now rode 500 km/h without problems or sliding noises.

Unless i really missed something here in my Hub 101 class, the windings are covered with insulation, so it's not enough just to touch the metal, they would need to lose their insulation as well before shorting.

This happened to me just now, one of the phase wire bundle (where it leaves the windings and go to the axle) was rubbing against the cover plate. Since this one is rotating, the insulation was damaged and the phase got shorted, to the hub, axle and the whole bike.

Easily repaired, but highly annoying when it happens.

What do you think?

Soon or later the winding insulation will break apart and say goodbye to the motor and controller.

Such a placement of the windings wire is ABSOLUTELY unacceptable for any kind of motor.

see the motor windings of a motor considered as a low quality

PA120077.JPG


this motor has many different design problems but:

the side rotor plates are glasfibre, not plastic as cristalyte - (better)
the windings has little chance to touch the rotor metal parts - (less chance of SC)

So I just wonder who designed HS35 and why it is so unprofessionally manufactured.
with a little effort from the factory, it can come much better.

Unfortunately , if not modified prior to first use, the chances of failure are very high
 
Every few months a malcontent like pavlik1 blows through the forums..... causing a fuss and being generally unhappy about everything. :?

If you don't like it then fix it - this is a DIY forum, not a "complain about Chinese manufacturing" forum. Take your motor apart, come up with the fixes, document your work, take pictures, and post it here to help others. If your fixes work then we (the people who import from Kenny who designed the motor you are bitching about) can pass the information along to him. If your fixes are **economical** and easy then it is highly possible that the changes could make it in to future models.

The "malcontent pavlik1" already opened the motor and documented with pictures the POOR quality.

The "malcontent pavlik1" will fix the motor which supposed to be a "high quality" before even turning it by hand, otherwise it will fail.

I wonder why you are not commenting the technical problems I find in the motor, rather twisting the words.
Is this hurting your business?

If your best friend Kenny had any desire to improve the motor, I already find lots of information about the motor problem on the forum, so why not already done?

What I am trying to do is to inform the future Cristalyte buyer about the real quality of the motor (with pictures) then he will decide if he can fix it by himself.

Yes, it is a DIY forum, but not informing the buyers about the known motor problems is not fair, isn't it?

I wish Kenny improve the motor building quality and give YOU a chance to sell more and better products

point. :D
 
Unfortunately its like most other things that come out of china... you get your good ones and you get your bad ones. QC just isnt the same over there as it is in Europe or USA. And lets face it, if it were then we would no doubt pay considerably more for the stuff from china. Unfortunately Pavik1, you have a bit of a stinker... sure we all have the wiring problem throug the axle, but my windings are much better than the ones you show in your picture (Dont forget these motors are hand wound by people, not machines so variances are to be expected).

Unfortunately the sad fact in this world is that while ever people like you and me buy items from china at prices cheaper than anywhere else on earth they will stay with the same manufacturing processes that lead to some QC issues at the real cost of cheaper products in general.

To some extent I agree with you. Since this is first HS3540 I opened, I was surprised of the windings quality.
At the same time paying for one Cristalyte 3 (to be exact - 3.7 times) times the price of one 48V1000W make me to expect slightly higher quality. Unfortunately my expectations turn wrong
The manufacturing cost and labor cost are fraction of what it the price we pay.

Anyway I will modify the motor up to my standard, but not buy another one before I am sure it is done in the right way.

possible solution to gain some cable space:

OK so Its almost like you are new to the e-bike world. Lets twist this thing another angle.
#1 You are unhappy with the motor so show us another motor to buy instead list where to get it and the price and show some take apart pics etc.
#2 What are the older motors you have experience with?
#3 I have over 500 km problem free with my fixes that cost me about $20 and 2 hours of my life so I dont see the reason to complain.
#4 If you are running this motor above 2000 watts you can expect problems! It is not designed for that so if you do run it with higher power then make some improvements so you can do so.
#5 Everyone on this forum knows we are dealing with chinese motors and their quality is good for china but not so good for comparing to $2000-5000 motors go figure!

I'm currently trying to find a good motor to use in a kart and trust me man when you look at how much a perm or a Agni or a AC20 cost you see real fast for 200-300 bux these are a steal.
Methods works hard for the community he never makes money and if he does he puts it back into more research for better things for us for the future but he is not trying to make money off us selling junk he is the only guy who will inspect a motor he gets before shipping it to you! If you don't agree maybe join another forum!

While i agree with most of your points Arlo, i have to disagree with this one. The motor is rated for 2000w and at 1000w its practically impossible to get it warm. Im now running at ~2000w and after a good 30 minute work out its just about warm to the touch. The only thing that may be a problem at 2000w is the stock phase wires as they are quite toasty warm by the end of it.

In all honesty, and i can say this because i have done it... running this motor at 1000w or below is not allowing it to show its true potential, at 800w it is very sluggish and at 1000w (i have run the motor at both these wattages for 2-300miles minimum) its marginally better at the top end but still a dead donkey under 10mph.

2000w is right arround the point where this motor comes alive if you ask me.
 
Ok sorry I never saw it was rated for 2000w post edited!
I base my findings off or experiance as well. Im just used to using motors at 2x-15x their power rating.
 
Haha, well we have already seen what happens to the HX series motors when ran at 2-15x their ratings.. and it didnt end well for many of them. Definately not a motor you can reliably run much over the rated spec without major work to it.
 
I have had extreamly great luck with cooling fans!
 
If you like the motor as it is, it is fine for me, but not pointing at the problems, will never lead to their improvement.

Unfortunately my experience with industrial electrical machines with power of 2 to 20 000kW do not allow me to accept the poor manufacturing of the electrical part of HS3540. The mechanical is also far from OK, isn't it?

So be warned and demand better quality for your hard worked dollars, there are no excuses.

Sorry, I prefere not to be involved in non technical discussions.

I think the point people are trying to make is that if you buy direct from china, dont be surprised if the quality is less than ideal. If your truly unhappy with the quality, consider it a (relatively) cheap lesson learned and buy from a high quality manufacturer, it will cost more, but you can be sure to get a top quality motor. Case in point, how much do you think those industrial 2kw motors cost that you mention? surely not $400 delivered. my guess is at least 5 - 10x that. The fact that the mods to make these motors more reliable are fairly simple does make it frustrating that the factory couldnt do it, but hey, 'least it means only a half to two hours work for a much better motor!

what is the other motor you've posted pics of?

So how much ? Where can we get it ? Whats the specs?
 
I do not say this motor is perfect, but for the price of XXusd is OK
let me ask the Chinese lady if I can put her contacts here, so anyone can approach her directly.
so far I have no complains about her service. very fast and very cooperative.
 
Hi all,

Since I am waiting for some PTFE cables for the sensors, there will be no work on the HS35 motor.

Looking at the inside pictures from the web, I would like to suggest all of you to measure the motor phase wires against motor housing. Measure resistance, and if you have insulation measuring device (Megger) give it a try.

I wonder how the winding wire when touching the frame will perform over the time. :idea:
