Does anyone know if you program an infineon do you have to program all the settings again?

I'm about to wire it up for the 3 way switch and I don't know what the phase and battery currents were set at and it's perfect the way I got it from cell-man!

I plan on having l-set at 20% and M at 100% and H at 120%

Thanks

Hi Mark

yes you need to do all the settings again., otherwise the programming may go back to default....

Get cell_man to send you an ASV file

Hey thanks for that ginge,

Are you on the beer again? hehe

Drink riding perhaps ?

[Whiplash]

Hey Cell Man, can I order a set of the new gears and a new steel side cover from you? My brothers old style motor needs these and he can't seem to get them anywhere else??

[Whiplash]

Do you have any of the 6t high speed windings? I am thinking of one for my commuter bike on 12s LiPo. Should be fast! Any idea what it would be on the flat @ WOT with say 30A?

[neptronix]

I have ran 12S lipo on a 6T motor. Top speed off the charger with pedaling was 33mph, or more like 31mph on the flat with light pedaling to help it get up there. Will sink down to about ~28mph constant when the battery is about dead tho.

30A gives decent torque too. It will handle 35A constant at ~44v nominal though.. no problem.

[Whiplash]

Cool, what kind of wh/mile were you seeing? How about higher voltage? With the 400 rpm loaded @ 36v spec he gives, I figured @ 44.4v it should do close to 40mph. Think I could do 18s @ 30a reliably if I try not to work it too hard up the long hills? The worst one I have is about 2 miles of a 6% grade going to work... So nothing too terrible..

What is the most recent price for these now?

[cell_man]

Best to send me an email if you want to get in touch, I don't check for sale threads much. Current prices are on the website in my signature. I see about 37mph or even a touch more on 16S A123, so about 49-50V under load for a 6T in 26" wheel. I have some 6T available and I even have 1 that was fitted with double (6pcs) 2mm^2 phase wire so 4mm^2 equivalent on each phase (equivalent to just under 11AWG).

[Whiplash]

Thanks! I will be in touch! I want to get it here soon. I also need to get a replacement side cover and a set of the new gears for my brothers bike..

Just a couple of comments to all those who are interested in the 6T.

I have the normal, 8T wind, with the IFRB 3077 controller. 9 fet. I have a 48v, A123 cell-man pack, 16s5p

With this combo in a 26 in wheel, is very very fast... scary fast, in fact. 30 mph is fairly conservative, in my view.

I have upgraded the following. just to cope with the standard wind (8t). If you are contemplating the 6t, consider the following:

Disc brakes...- should be mandatory at these speeds.... going fast is great.. but being able to stop is even more important.
I had some very close calls until I realized that I had to allow for the greater stopping distance when you are going that fast!!
The big MO... ie momentum, get very dangerous at higher speeds and most regular bicycles are simply not designed with those speeds in mind.
BTW, check your brakes more frequently, they wear out really really fast!!!

Helmet (Helmut?) - I would say mandatory, even with the "slower" wind... 30 MPH will crack those foam bike helmets wide open
With the faster 6t wind, you are going at motorcycle speeds... use the proper safety equipment!! A good quality basic motorcycle helmet
is only about $50-100, the better ones are more... but at least get the minimum!!

Dual suspension - highly recommended.. those bumps on the road can definitely adversely affect the sex life of male riders for sure!!

Lights - night riders should realize that at the speeds you are going, reaction times are cut down tremendously... so regular bike lights simply
will give you time to react and avoid the dangers on the road... get quality 1000+ lumen bike lights... ebay has a bunch for under $100 some over 1600 lumens
but given that ebay sellers tend to overrate the specs, you can expect about 10-20% less then what they rate.

6t is clearly a fast wind, but use your head when you decide to go that fast... before it hits the ground at 37 MPH...
If you are not going to use the proper safety equipment, at least, be kind and fill out an organ donor card before riding at these speeds!!

Let me add...
I dont think you need fancy hydralic brakes, a BB7 would do. I woulda use a cheap disk brake and get a frame with full suspension, pot holes can make you fall easily on that speed.
And get a real helmet, Im using a motocross helmet just for the sake of safety, it looks ridiculuos but bike helmets were not made to handle such speed.

[Whiplash]

This is all true! I have gone down @ over 60mph on two wheels and let me tell you, its not fun! My off road R/C bike will do 40+ in high gear, and I wear a helmet too! Its minimum protection @ these speeds! The more the better.... road rash SUCKS!

[neptronix]

Gblast, excellent points. Once you get above regular bicycle speeds, all this applies. I would say the same for the 8T motor - if you pedal hard with the right gear ratios, it will do 28-30mph when 10S lipo is fully charged. That's definitely fast enough to get you into trouble.

My first bike had a ~17mph 250w cell_man kit and at that point, all the regular bike stuff was just fine.

As for brakes, i have a mechanical bb7 in front. It's strong enough to lock up the front wheel on 1.85 wide michelin tires. It also managed to help crack a cheap aluminum fork right in half. That's good enough for me.

I have the 6 turn, on 36v (38v actual, LifePo4), it pushes 32mph if the road is fast enough or you have enough amps. 30a should be nice on it. It's still got great torque, for the speed it's wound for. A nice wide range of power. Pretty quite, sounds like a Prius going slow.

Cellman has been the most reliable person I have had to deal with and I buy a lot of kits and batteries.

I cleaned up in here a bit... Miuan dude, show some respect.. we let just about everything slide in this place but the In the Market area we try to keep it clean.. if someone points out a scam that's fine but pissing on an asking price is not cool.. moving on..

[cell_man]

Thanks! I will be in touch! I want to get it here soon. I also need to get a replacement side cover and a set of the new gears for my brothers bike..

No problem, give me a shout and I'll sort something out for you. The side cover might have to be black though, Mac mostly stopped using the silver some time back.

I know the newer version Mac has better gears and such, but other than that, are there other differences between the new and the older(silver) ones?

Does anyone know the limits of the older version? (Not that I'm pushing them now, but for future consideration).

I should of got the newer version from ya, Cellman.

The limits I'm sure if you are using the older gears are with the controller cell-man gave you, with the settings he programmed it with and with the voltage he recommended you use it with and no more!

The limits with the new gears are with the controller cell-man gives people for that motor too, with the setting he programmed it with and with the voltage he recommends and no more.

I over power my motor and know the risks, if it breaks, it's my fault!

The new mac motors can take a lot of peak power, great for acceleration and level ground, when you get to very long steep hills is where you might have issues with heat, if you live in very hilly or mountain areas, you are best to ask cell man if the slower wind motor is best for you!

I love this motor's power for it's small size is amazing!

I love to cycle and love the mac's ability to free wheel. It makes a huge difference over direct drive motors.

The motor hasn't really changed that much other than new gears and a few small revisions here and there which don't really effect power handling. The motors from some time back did use rather undersized phase wire, newer motors use 2mm^2 which is written on the side of the cable and even though some of the phase wires in the past were a bit small, I never had the insulation failing. The main bits haven't really changed, so don't worry, you are not running any sort of high power with your setup, so no problem whatsoever IMO.

To be honest I probably set the 12 fet controllers a bit on the strong side for the Mac but touch wood I haven't received any complaints of broken bits so they seem to be holding up just fine even with pretty high current levels of 40A plus. There's not much that you couldn't fix yourself and I can normally get any parts pretty quick and at a reasonable price, so I wouldn't worry too much. Nobody has even reported melting the solder between phase and the windings, so they can't be using them as hard as I have

Paul, do you happen to have any news about a bigger geared motor? Sized like a clyt HS hub motor, but geared.

[o00scorpion00o]

Haha that would be a frightfully powerful motor!

[cell_man]

Paul, do you happen to have any news about a bigger geared motor? Sized like a clyt HS hub motor, but geared.

I would love for a new higher powered Mac motor to be made and if I can swing a few samples I'll definitely share what develops on ES.

If it happens it will have to be a wider version of the present design for the time being. There is too much work and cost involved to go to a completely new design unfortunately. Mac don't sell big quantities of their Hub Motor and they don't make a big profit on them either. Their primary products are shaft output industrial motors in the 300-2000W rated power range. Those products pay the bills and keep them busy, not building fairly small quantities of geared hub motors in a market that is very competitive with lots of fairly cheap mass produced motors around, unfortunately.

I was only recently discussing getting a wider version of the hub motor made, maybe double the stator width, but you'd have to run a single speed freewheel, use a wide dropout, or possibly extend the motor out on the disk side and use an oversized disk. This could be possible without too much work as you could adapt much of the existing parts, at least for a few samples anyway. I will try to make that happen. There was talk of building a geared hub around their high powered industrial motor, but that would require a new hub design and that is not viable at the moment unless a customer comes along and orders such a design and pays development costs. A Mac with roughly twice the stator and magnets as the 500/1000W should be pretty potent I would think when you consider the 500W are good for 30mph plus for extended periods and 2500W plus for bursts.

[o00scorpion00o]

That sounds cool Paul!

Do you think there could be a wqay for them to water cool a motor and maybe install a temp sensor?

I would imagine a motor like that to sell in very large numbers, the extra development costs might actually make something like that worth while!

Scorpion a Big Mac (much wider, but not fatter) wouldnt need alot of cooling I think. The real problem is there is no much market for it. But this ll probably change as ebikes get more popular....
