Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

Great news my replacement axle arrived as well as a COMPLETE 4t * 16 rotor winding and shaft for a far easier install. Cost of both was just the $80 air shipping charge with UPS and it came within a week or so. 20160915_150936[1]__1474410625_21148.jpg Everything looking very nice indeed...time to go...

Re: 18F Silent Controller 36-150V VAR.REGEN/BT Progrm/GPS-$1

Well I'd like to get one to test myself as soon as possible, sounds like the answer to the r12 mod scaling issue. Great work, really exciting development. Btw, I'm back on the road again on my EEB, so I gotta figure out the whole 3 speed setup thing that seems the same power to me whatever mode is s...

Re: Setup of CA temp sensor

just check resistance with a digital multimeter. this will give you certainty. is it 10k or 100k? I do not know just yet... I was out riding it first to test whether it actually works to gauge rising temps and is the wrong spec or is just plain faulty. Well, it seems it's working all right because ...

Re: Setup of CA temp sensor

Wow, so Peter the main guy from Leafmotor just emailed me back less than 15 min after sending him an email. He claims the tag with the 100k is WRONG! and that ALL the therms he installs at Leaf ARE 10K and have never changed?? I'm not able to argue with a blanket denial without any king of data to b...

Re: Setup of CA temp sensor

Yes I checked the tag he sent and indeed the R25=100k not 10k :( so it seems they used a different sensor last year to this. I emailed Leaf about it but I don't expect much joy. I'm not interested in trying to ruin it by attempting to affix one and I certainly am not paying more! I expect I'll just ...

Re: Mxus Temp Sensor + Cycle Analyst

I'm having a similar issue but I definitely have an NTC type therm, not linear? I'm still getting a -18°c reading on it for some reason tho... I have everything setup exactly as it was on the last (same) sensor, so it's a Lil confusing trying to figure out what is wrong? A polarity issue was mention...

Setup of CA temp sensor

Hi guys, Well I'm having an issue with seeing a negative temp reading on my CA temperature monitoring. It currently reads as -18c? I had to change my rotor winding after a broken axle on my leafmotor, and on this new one I'm not understanding the reason for the issue. The previous sensor was an NTC ...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

if you mount a hub motor, you should think of the following: the less you tighten the axle nut, the more torque the axle can withstand. or with other words: if you tight them hard, it need less torque to break the axle. because of that you want to have dropouts with clamping mechanism, especially i...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

This kind of things mostly happen because of the dropouts on the bike. Was you dropouts tight? If you have a little slack then you can twist your axle. 0,05mm of play is enough to snap it off! I am pulling 9kW peak, regen hard with my midi-e controller on 1500W version and it is still doing fine. K...

Thanks for the advice, I'm not even sure how the axle is attached? The video I've watched from the QS factory just show them assembling the press in bearings, I guess I'll have to find out. It's also a little confusing to me because the leaf rep replied initially to my email and photos that ... "Sub...

Well the pics show the state of the axle, no twisting at all, just sheared through clean! I emailed leaf about possible warranty claim for the axle, and get this... He says in over 100,000 sold motors he's NEVER EVER HEARD of an axle EVER failing! Obviously I pointed him in the direction of ES, (ins...

Re: 18F Silent Controller 36-150V VAR.REGEN/BT Progrm/GPS-$1

OK guys, disaster hit on my ride today, I guess the axle was more damaged from that reverse torque on setup, and when hitting the brakes the regen torque (turned on to 70 I think) caused the axle to shear right off. Axle failure is a scary proposition on an Ebike, I guess I'm very lucky it happened ...

Re: 18F Silent Controller 36-150V VAR.REGEN/BT Progrm/GPS-$1

Finally, congrats! And it is pretty instant power, probably something is co figured for delay. The first thing to check is the CA throttle out setting. It is configured to delay throttle by default. I set all values to 9.99v per sec, so there is minimal delay. Also, check if throttle delay is disab...
