Crystalyte HS4080 72V 50A APM Display kit

[kentlim26]

troque arms are not difficult to build. just find some steel plates, steel bars n cut , n file to the size. the reason using a troque arm is to prevent damage dropout.. as for me, i wil not run a hub motor with no troque arms. my current common hub motor 48v 1000w ,top speed 60kmh have damage the frame dropout, have burst the phase wires and short all the hall sensors.

need both side troque arms,

Thanks kentlim this definitely Will be the next project , the biggest problem is that i cant full enjoy the bike because i have my eyes on the screen trying to keep the torque under 100NM

 

[sardini]

The battery from Empty to full charge did 4 hour and 40 min. 90km per charge maybe .
this 4 bars don't work........... i notice that the battery 20km before run out of juice had gain voltage

 

[sardini]

i did a small speed test with the controller tuned at 40a. The acceleration from 30 km 77 was brutal . the feeling at this speed was like going with the car 250km/h

 

[sardini]

its easy to put wrapping film in the Battery and the bms , You nee to put some silicone in the throttle and display wires also.



I made some torque arms , i did a fast ride . it was forecast for rain..



When arrived home i decided it was time for DOCs BBQ temp sensor....(SO MUCH FUN!!!)

I forgot to mention that one axle bolt kick out and was useless, i was lucky and found a replacement... change both of them as long the axle is OK..
First i saw the the timelapse video from GCinDC

Then
I drilled a little the cable canal in the axle with a cobalt drill.

Then i asked doc how to drill the side halls

Doctorbass wrote:
No... take a look of the side cover in my giant Dh thread.. you'll see..

you can drill many small holes right on the max larger diameter on the side cover.. ( near in front of the magnets and the gap between the magnets and the stator this is the area with the larger diameter that the air is trapped into... or the area where the water can sit... thhat's at that location that you drill the small holes

or.. take a look on that thread: http://www.endless-sphere.com/forums/viewtopic.php?f=3&t=18473&hilit=giant+dh+comp&start=60

PLEASE PAY ATTENTION... THE ANGLE ( orientation) OF THE HOLES IS IN THE WRONG WAY... that's the error i made.. so when you will make the angle on the holes DO ON THE OPPOSITE ANGLE !!! for the small and for the bigger holes

Doc
Hi,

Drilling holes always improove the motor efficiency and reduce heat. the cons is that water and particules can enter so you must take care of that.

the holes on the larger diameter must point in a direction to exit the air and the holes on the smaller diameter of the side cover must be pointing in the reverse direction to force air to enter. the air will naturally exit to the larger diameter with centrifugal force.

Doc

I did it in a smaller scale......


And install the BBG sensor as doc presents here

I ride it uphill 72v 45A (ambient 22 Celsius) the motor 53 Celsius

next ride....



I need docs torque arms..

Thank Doctorbass, GCinDC, and Justin.

My 72v 20A Expedition Battery fits in the triangle!

http://ex-battery.com/Html/About1.asp?ID=50


The battery actually fits in the triangle !!! and you can even petal !!
Now the bike has much much much better handling!!
====================================

Wow! REally dig that you fit a good sized battery in the frame space. Assuming you actually installed a 72v x 15 ah.

Where did you buy the bag? I'm assuming that the battery is the standard size in the spec sheet 360x130x90

Hi dan974

Its 72V 20ah but i will Know for sure when my speedict data logger arrives

i have 150 mm between my nee and i can petal when needed , it's not comfortable for continuous petal though.

I did 70 fast km yesterday and seems to have 20 more.

Does anyone have an opinion on buying the 35 mm or 40 mm cyrstalyte motor?

HS3540 or HS4080

Got this quote from Kenny:

Thanks you for you mail.
The H35 motor is 35mm stator, H40 motor is for 40mm stator.
The following is for sample price.
1 x HS4080 rear wheel motor can for 36- 72V price:$280.00
1 x 31mm 26" double wall rim price: $20.00
1 x 12G spokes (36pcs/set) price:$10.00
1set x Motor laced with rim price: $25.00
1 x 72V 48A Digital sensor controller for Crystalyte APM price:$150.00
1 x Crystalyte APM Display price:$65.00
1 x Twist grip throttle price:$10.00
1 x Electric brake cut off switch prcie:$10.00
The battey for Express is now very difficult to export.

I bought the HS4080 motor from kenny, arriving in a few days.

Now I need to decide if I want one 20AH or two 15 AH batteries.
Will take measurements and see.

size of the 20 AH one is 20cm*18cm*15cm

quote from Quentin from ex-battery.com:
"We have sell the batteries in Europe more than 5 years.Special for CRYSTALYTE motor and controller http://www.crystalyte.com
We give customer a 12 month warranty for battery and charger."

I could not order the battery from Kenny because of "very difficult delivery for express or air"

I did 70 fast km yesterday and seems to have 20 more.

Wow that's huge range. How much pedaling and what speeds, hilly or flat, normal wind, asphalt roads, no stops?

Good to hear i think this motor balances between weight and performance in a killer price!

The measurements are correct i will update with photo

I am commuting in a 4 million city... i do 40-60km/h when i can...

and keep my motor below 80C for efficiency
i believe next week you will have all the data

I couldn’t resist looking inside the Battery.

View attachment 2

It was for the best, because wasn’t so rugged as I thought... so I made new base and now the weight is supported from two sides. I also added some packing foam




I must say that I measured the cells and all was balance at 4.2V.
The Bms has charging port which balances the cells!! all for 700$.

hey guys , where is ... http://www.crystalyte.com/ are they closed ??

 

[dan974]

advice : as I see your woody piece cracked, you would better no put a screw in the wood by end...not efficient for tearing...and in small pieces make a first hole 1mm smaller not to get the wood cracked =)

advice : as I see your woody piece cracked, you would better no put a screw in the wood by end...not efficient for tearing...and in small pieces make a first hole 1mm smaller not to get the wood cracked =)

Thanks dan but its a special quality wood . i did the cracks...

Woods placed on a wagon and inject special industrial furnace installation to create a vacuum inside the wood during the impregnation. Then bubbled in the oven suitable mixture impregnating wood preservatives and then exerted pressure regulated so that the mixture to penetrate through the heart of wood is desired. The mixture to be over from this process is absorbed, and returns again to storage tank located below the furnace chamber. The woods are still in the oven as long as needed depending on the quality, type and dimensions. Finally the most impregnated wood removed from the furnace and transported to places where they will dry. The process of drying and moisture when it goes on the market are equally important for the quality of impregnated wood during use.

I removed the bag from the battery and now i don't even notice that is there!

hey guys , where is ... http://www.crystalyte.com/ are they closed ??

They just send me another package . Try to contact with kenny kenny@crystalyte.com

Speedict is here i will post soon!! I also put a resistor between the battery and controller as doc said . soon guys


Speedict is here!! i will d

yeah i payed for some spokes from crystalyte and got no reply from kenny, jusy tried kenny@crystalyte.com so hopefully he replies.

But shutting down the site? Lol
Makes no sense. Unless of I'm not getting something :?

 

[sardini]

Guys
controller blow up 52 amps from the battery i will post speedict data tomorrow

 

[dan974]

bouh.....that why I was freezed by K. controllers. Hope you find why.

 

[sardini]

AT the end of the chart the controller blew up.

http://chart.speedict.com/?weblogid=ZV60101q05a0105

That's doc diagnose

f your motor would suddenly be like a shacker and that the wheel have big cogging effect. in this case it is usually a blown controller mosfet... when the wheel try to spin, one of the phase of the controler is short and make a short curcuit to the other phase and blocg the magnetic field, creating that kind of restriction.

Turning the wheel freele is like turning a dynamo.. of the output wires are connected to something that have a short, the dynamo will offer blocking effect to that rotation and that is what you might have in your situation.

If so, it is hard to tell why this hapenned... maybe your controller was set too high for the phase current, maybe it was too hot

Please give me the MAX details on the condition when it happened

Doc


Ok so there is a method that was posted on the forum to test your controller:

on ES Wiki :
http://www.endless-sphere.com/w/index.php/FET_troubleshooting

or
http://www.ebikes.ca/troubleshooting.shtml

or
http://endless-sphere.com/forums/viewtopic.php?f=2&t=43297

So you also think it cold be when you pulled hard the cables accidentally?.. maybe? I think not.. unless you stripped the wires and that have make them touching together..

interesting according to your uploaded speedict log (just extracted a portion of it), your speed controller seem to react cut off current (~50A) very slow, sometime it react in ~4 seconds but sometime react as long as ~10 seconds, it doesn't look good

you should measure the temperature of its mosfet, because current may not kill its mosfet but temperature can (if under high load) ....

The funny thing is that the same morning it was a "five minute gap decision" and i didn't put the speedict temp sensor...
as you already Know you can't programme this controller or you can? I will try to fix it but the last couple weeks to much work.

Your package from Edward Lyen is on its way. You can track it online using this tracking number

Tomorrow (i hope so) a 24 fet will be at home ! help needed with this controller.

 

[GCinDC]

how are you sure it's the controller? how do you know it's not the motor?

what exactly happened? i can't see the speedict thing...

and what exactly is it doing now?

does display light up when power is on?

sorry to hear about it..

Hi Greg, thanks

It felt like engaging regen .My torque arms (wannabe) were relocated and were hanging freely from bike. they were made for one direction support.

The throttle had no response at all.

Screen was indicating no fault .(it can detect shorted hall for example) ..

i couldnt move the wheel and i was afraid to move the bike . i called my wife.. (she came without the bike rack, she thought that all the bikes are like my little brompton..)

Now at home when i disconnected the Green face cable the wheel runs freely again , when i connect it like a dynamo

Maybe the speedict think needs to be seen from one person only i don't Know.
