Crystalyte 5404 / 5403 UPGRADED! LAST CALL

[fractal]

update: 5403 and 5404 avaiable

What you be the specs on each motor if I would be running 24s 3p?

[wojtek]

update: Kenny is willing to send the motors to individual addresses if we get a good number of orders. Lets aim for 30!

[Cheeseboy]

There's no chance of one somehow getting to Aus is there?

Thought I might as well ask

If not I guess I'll just hide until the next Aus group buy thread shows up

[Philistine]

Hey Cheeseboy, if it made it doable I might consider going in with you as well, and we could get them both shipped to you in Sydney, and I would get mine from you. Just throwing it out there in case that made it more viable.

Would that include us freaks in the Antipodes? Or only for US/Euro addresses?

[Andje]

if there is a good number of canadian orders (or AUS/NZ orders for that mater) could we look at splitting the final shipment into at least two different countries? For us shipping to the US and then up here is brutal, whereas it's infinetly cheaper and faster to not go through customs twice.

I'd be very happy to do that. Odds are low for Kenny agreeing to send just two of them our way, but it's worth a shot for one of these puppies!

[wojtek]

i don't see any problem with sending to australia. as said, it is possible to send the motor to your door directly from crystalyte factory.

all i need for now is how many people are ready to commit to buy and pay in advance.

all you need to know i guess, is the shipping cost.

I gave an example of USA address to Kenny to calculate the shipping costs.
Another option is sea shipping if we get good number of motors. One of the members here offered his help to get the motors by sea.

[wojtek]

I asked Kenny about possibility of getting a single speed 5404. to make the axle shorter to fit more standard 135mm bikes.
He said it would be possible but MOQ would be 50 pieces.

i was thinking the shorter axle lenght would encourage more people to get those motors...

[andreym]

Count me in for 2pcs. 1pcs 5404 and one 5403 please

[Farfle]

One 5403 please, Not sure when payment is due, hopefully not sooner than end of the week.

[Doctorbass]

BTW... wojtek, can you ask kenny to make them with 10 awg phase wire instead of 14 or 12 like usual?

it's not really complicated for them i think...

@Doctorbass- Which controller recommend for 5403 and 5404 and Edward Lyen recommended me run at 24 fets controller to avoid over stress on the controller like 5303 tend blow up the controller easily.

that is exactly what i got: http://endless-sphere.com/forums/viewto ... 31&t=19719

re the wires, i am thinking to not only ask about 10awg wire but also upgrade of hall sensors based on Lowracer experience:
viewtopic.php?f=3&t=24805&hilit=5404&start=45

"BUT, I must admit that in a 5hours test run one of the china hall sensors is broken!

I've got figured out, that the hall sensors, the ball bearings and the axle are cheap china trash!

Now I change the 3 sensors against HONEYWELL SS40,
and I change the ball bearings against SKF 6004-2RS / SKF 6005-2RS,
and I change the axle against a new selfmade 12.9 STEEL AXLE with build-in torque support!"

I dont know what of those things Kenny will agree to upgrade, but one sure thing - i will push hard for those changes. No point to get motors that will stop running after short period of time. little problem for experienced people who can fix it / upgrade it. But like me, i cant do it so i want it right in first place.

Will see where i go with it. But again, our power lies in good amount of orders, so please keep coming

@Doctorbass- Which controller recommend for 5403 and 5404 and Edward Lyen recommended me run at 24 fets controller to avoid over stress on the controller like 5303 tend blow up the controller easily.

any controller can work with the 5403 or 5303.. if the voltage of your battery is lower than the voltage of the controller mosfet...

the problem appear only if you drive.. let say 24s lipo ( 100.8V full) on a controller with the best mosfet.. but that are rated 100V... the problem is that at low rpm with agressive throttle demand, the phase current make the controller to receive HV voltage spike and it blow the mosfet...

BNut if you drive let say max 24s LiFePO4 or 20s lipo, you will not have any problem anyway the controller is a 6 mosfet or a 36 mosfet... you just need to respect the thumb rules of 50A phase current max per 6 fet and you'll never haver any problem

ex.. a 20s lipo setup with a 5303 or 5403 with a controler of 18 fets and 75A battery current and 150A phase current will work perfect

But personally for more torque and safety i would go with the 5404..... it remain the best winding ever made i think..( easy on the controller if you drive 100V battery and 100V fet controller)

I dont understand why people have so many problem with teh hall sensor... generally it's the wiring that melt because it's not rated more than 105 celsius... my 5303 had over 250 celsius o the winding and the hall remain ok... ( but i had replaced the wire with teflon skin wire)

Doc

[markcycle]

Can you tell us the RPM/volt of the 5404 and the 5403?

[wojtek]

actually Chris [lowracer] said that the axle wasn't too bad. it is only the hall sensors... well won't hurt to ask for an upgrade

[ryan]

Count me in for x5404. Near San Francisco, US.

+1 on requesting upgraded wires and halls

Can we get some more info on stretching 135mm cromoly dropouts to 150 and/or modding the axel to 135? Is the axel mod something I could get a local machine shop to do for ~$50? I'm considering stretching out a Yuba Mundo to 150mm.

YEP, that's right!
If a hall sensor doesn't work, you can feel that, then the motor don't run!

All in one, this motor is a masterpiece, high torque without gearboxes.
I've got ridden it now more than 3500Km. Excellent!

Here are the details:

[NeilP]

I do not know why, but my motor came with what I thought was 10 gauge as standard, but maybe it was 11
.I got my 5304 from Maxwell65 and he says he did not ask for thicker gauge wire, that is just how they cam.

Kenny supplied me with more of the same wire, and I only just installed it back on my motor.
I did not like the idea of having a big plug of andersons on the outside of the frame, no matter how easy it makes the wheel removal.

I have fitted wire in one length direct to the controller, so I have only one connector neat the controller.

Yes, OK, there is the argument that you take a bigger wire from motor to controler to reduce voltage drop along a lenght of wire, but I am of the opinion that I will probably get less voltage drop with a single length and one junction from a single connection, than having two connections and a 2 ft length of thicker wire.

This is the spec of the wire he sent out




49 strand conductor:

Conductor diameter:
0.1060 inch 2.69mm

Strand diameter
Max 0.0150 inch 0.38mm
Min 0.0125 inch 0.31mm

Overall Diameter
max O/D 0.1360 3.46mm
min O/D 0.1305 3.30mm

Insulator Thickness
0.0250 inch 0.64mm


Here is the response I got from him when I asked if he had a part number for that wire if I wnated to rder any again

Hi Neil,
Nice to hear you get the order.
The wire called less resistance 4 mm2 ( square ) for motor.
But it will make things simple if we called it for Crystalyte X5 motor's phase. So we will understand.
Kind Regards
Kenny

So 4mm2 is closer to 11 gauge than 10 gauge, but I am not sure if you would get 10 gauge to fit...it may be just a little to tight

But what ever Kenny calls it, and the size he specs at 4mm2. I know it is as thick as this stuff in 10 Gauge, if not a fraction thicker, as I had some of this on the bike till the 'correct' stuff arrived last week

talking about wires, i still have plenty to high quality stuff to get rid of in case you wanna build new battery packs for this masterpiece motor..
