Puma 500W Rear-140USD. 500W Front, 350W 135USD

[veloman]

Thanks for the info. Last question - I promise! Okay I wanna use 20" wheels and Should I go for fastest winding geared motor such 6T? I am going use 16S4P (66v nominal and 20Ah). I aim for between 2500-3000 watts (50A and 100A burst) on 6T. It should be very quickly acceleration and fast! I live on flat terrains and if i am encounter the hills and it should not give me any problem with the 6T on 20" wheels.

I am going make a bunch of orders lot stuff coming soon.

I don't think you should be putting 50a constant, or 100a peak into a geared motor.

The 6T motor with the 12 fet controller on 48V in a 20" wheel will have good power and speed on around 48V. I think you are mixing up peak and phase current. 100A at 48V is almost 5KW, that is too much. The 12 fet controller is shipped with 40A battery current limit, that is plenty enough.

Does the 6turn MAC comes as a front hub?

Reason I ask is that I'm looking for a high speed lightweight front hub for a friends 16" Brompton conversion. I think the OLD (fork opening) is ~80mm which maybe we can stretch to 100mm or so. The 6T MAC would be a good option if we could stuff it in there, and maybe run it at 20S if top speed seems uninspired at 16s.

Hi- The answer is no, I have asked Paul (Cell_Man) about the front motor and He currently has 350 watt as a front hub motor. Mostly the rear hub motors that have capable higher watt. I think rear hub motors are more than 135-150mm wide axle. Paul or someone can confirm this.

The front 500W can come in any of the windings, but I do not tend to keep the front 500W Mac in stock. For disc brake you can only go with the 350W front motor, the 500W is for rim brakes only.

I can add a particular front 500W to a future order, but it is difficult to commit to a time frame. I do try to keep the standard front and rear standard 350W Mac in stock (about the same speed as a 10T 500W) and various rear 500W from 12T to 6T. I've attached an outline drawing for the front 500W. The smallest rim I stock is 20", but 16" should be possible with stubby spokes, not something I can offer at this time though, plus the Mac is 36 hole, they don't generally make 16" with 36H.

hello cell_man,im looking to buy 2 rear 135 mm geared 500w hubs with controllers.ive emailed you from youre site but thought i would post here also.thanks. mark.

Mark, please PM with your email address, or just send your request by PM. I do not see anything in my Junk folder. Please use the hotmail address as listed on the site.

Hey Cell Man, I have a question, it may seem strange, but can the side cover from the rear hub be put onto the front hub? I am thinking of a MID drive for a bike and it would simplify the build if it would work.. Also, is the 500W front the same motor as the 1000W rear? What is the difference internally?

[gensem]

Hey ppl,

Whats the max gauge I can use for phase wires? Will 13awg fit inside the axl? if im not mistaken the original ones are 16awg.

[chroot]

Here Cell_Man's comment on wiring size.

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).

I have 12awg silicone wires at hand and im mostly sure they do not fit in the axl. Did anyone fitted 12awg wires inside MAC axl?

[cell_man]

You need a thin insulation to get the max copper in the axle. The standard wire for the Mac 500W is now 2mm^2, about 14AWG, older models may have been only 1.5mm^2. the size is generally written on the cable sheath. 3pcs of 2.5mm^2 or maybe 3mm^2 should fit, but you can squeeze in more by using 6 wires, 2 in parallel for each phase.

You could always just use the existing cabling, but doubled up, but you do need to be careful the cable is not cut by the axle. The original cables are pretty good IME, they may get hot, but I've never had the phase wire insulation melt.

[gensem]

Thanks for the fast reply Paul,

Im yet to have problems with the stock wires, but im still unable to ride due to my last crash and was searching for something to do....

hey CM/others, I have a few questions about the macs... I'm using a HT on 24s lipo atm, but the weight is kind of a killer on off road trails, so a MAC looks like a good option untill I get a mid drive setup...

thus im interested in the torque rear motors, probably a 200rpm version. The HT hits about 65km/h on 24s, but since I almost never bother going above 50 or so, the lower kv mac seems like a good option (would it get me to 55k on 24s?)

Im running 24s on the HT at the moment, will the mac be ok with this? im not sure if there is a limit with the gears etc to a cirtain rpm? (ill be limiting the amps to ~30, and normal use will be <20.)

I've pm'ed and emailed you CM with similar stuff and requesting a shipping quote, as I haven't heard back from previous attempts of email only.

cheers all.

24 series is way, way too much. That's 100 volts give or take, right?

Neptronix, whose thread you should find, pushed his 8 turn MAC to 75 kph on just 76 volts and he admits that is too much.

48 volt (52.8 volt nominal) is enough to get me around 52/53 kph with pedalling on 100 per cent speed. Granted the torque 10 turn version will be slower, perhaps 20 per cent, so 60 volts will give you about 50 kph.

I don't know what a HT is but I assume it is a direct drive hub? If it is, there is simply no comparison between the speed and acceleration of a MAC and a direct drive at similar voltages. The MAC is much faster and much quicker.

cell_man was away for a couple of weeks so he probably has a mountain of messages to get through.

about 93V nominal. the HT is a DD cristalyte hub, slightly higher kv than the 200 (about 230 or so). from my best calcs, the 200 should get me to about 55... (200/36v, x92v, *2meter (wheel dia), *60minutes *.8 for loaded speed), though maybe im missing something.

already spoken to neptro, who said he killed his on 4kw (broke the old style gears)... ill be keeping this to about 30a max, from what I can tell this should give me slightly more torque across the entire rpm range than my HT, in a smaller lighter motor. Im not going to run these power levels often either....

I went on your site and i don't see any puma 500 watt motors for 140. cheapest was 250

[tekillah]

Send him a PM here for details.

[lcyn]

I have a question regarding the MAC 500w rear hubs (8). With the new composite gears, how noisy is this hub? How does the noise level compare to a 9c DD?.
Thanks

[Spicerack]

I can't compare to a 9C but mine is not at all noisy when running. Tyre noise from my chunky tyres just about drowns the whine out.

WISH THEY WERE!

Prices are up a lot due to the NEO mag shortage! Shortage is like the gas shortage here in the states. Yes there is a shortage but not at the pumps, just our pockets!

[Whiplash]

These are very quiet motors, dont let anyone fool you. They are no noisier than a DD bub if running speed for speed. All motors get louder with more power, and these whine ever so slightly, but not ANY louder than any powerful DD hub I have seen... Just a different type of sound, think gears, not power pulses making the sound..

[maydaverave]

What wheel sizes are available for the mac from cellman? just 26"?

I think the info you need is on the page above if not just go thru his motors to see.

Cool thanks I must have missed that.
