Re: Critique this performance velomobile idea

I finally topped it out. The Cycle Analyst says I reached 46.0 mph. Not bad for a 46.8V nominal pack limited to 1,250W! It may have a little more in it once I get the tail on and do some more aero tweaks. It said I was using 513W human power at the time, and I had it set up to where human power shou...

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

I intend to modify mine in a similar manner at some point in the future. How much extra weight and pedaling difficulty did the cooling fans, ferrofluid, heatsinks, and vents add while riding unpowered, if it was even noticable at all? What voltage can these be run at before any arcing over occurs? I...

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

I other words a PR with good heatsinking could max the Leaf, no need to go to a bigger BAC? It can almost max it in terms of peak power, but not torque. If I'm not mistaken, a Leafbike motor can take 200A phase current for a few seconds at a time(somewhere less than 10 seconds). The Phaserunner onl...

Re: Critique this performance velomobile idea

Be advised both those controllers have a 90V limit. If you want to be able to run it hot off the charger and/or with regen, you'll be limited to a 21S pack (88.2V hot). I mixed their specs up with the powervelocity one you mentioned. But yeah, that is correct. Kelly KEB84801X is rated to 105V (24S)...

Re: Critique this performance velomobile idea

It's nice to see you up and running, and reading all your details! From what I remember, Leaf won't make the 1500w 35mm motor in a 3T, only the 1000w (27mm?). The 1000w may be advantageous for its reduced cogging losses anyhow. The goal IS to keep the thing as fast as possible when operated purely ...

Re: Critique this performance velomobile idea

I had to abort the top speed run. When I got to the location I was going to try it at, it started snowing. While it was fun sliding around in the snow at 40+ mph when I first got it going, being pelted in the eyes by snowflakes at that speed is no fun, and I'm not dare going to suffer that at what w...

Re: Critique this performance velomobile idea

I put an almost empty pack(CA indicated nothing in the battery charge indicator, but resting voltage was about 44V, demonstrating it maybe had 20-25% charge left) up to the Satiator charger today. It charged it to full in 2.5 hours, putting 7.4AH back into the pack, the pack being rated 46.8V 10.5AH...

Re: Heavy Duty Torque Arm - Disc mount, clamping optional $35

I haven't drilled a hole to clamp it yet and have it installed as it came. So far, at 1,250W and 96A max phase current in a Leafbike 1500W motor with a 4T wind, in 100 miles of powered riding nothing has come loose! It has a Grin Torquearm kit on the drive side as well.

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

Wanting to mount both of my battery's then I would have 72 amps continuous. That would keep the Phaserunner in thermal roll back most of the time. Correct me if i'm wrong. With an appropriate heatsink, the Phaserunner should be capable of 70A continuous. If you only hit 72A most of the time, I woul...

Re: Critique this performance velomobile idea

So far, with the tail removed, the CA3 indicates a consumption of about 8 Wh/mile when not riding like a jackass and doing about 30 mph on the flat, with pedal input accounting for roughly 1/3 the motive force. I can ride 30 miles on this 46.8V 10.5AH pack and the CA3 indicates it's only about half ...

Re: Sempu BB + cycle analyst assist not working well

I have a 2-wire Sempu with a 115mm spindle width. Mine initially gave wonky readings where it was displaying massive amounts of human power with the rear wheel lifted off the ground and spinning the crank gently by hand. I had to adjust the Nm/V parameter down from the 50.0 default to 7.5 Nm/V to ge...

Re: Phaserunner not being read by PhaserunnerSuite

I did send some emails to Justin from Grin Technologies, so he might have an answer for me to share here when I hear back.

But at least I got the Phaserunner working. That is what is important.

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

Don't know first hand. Supposedly it can handle 70A continuous from the battery if I install a heat sink, which at 75.6 Vnom, is about 5,300W.

It has handled 1,250W very well today.

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

It appears that I got the 4T wind. My motor is built into a 26" wheel and I have a Schwalbe Marathon Plus tour 26x1.5" tire in the back. When I got the Phaserunner controller to spin the motor, it spit out to the laptop that the motor was 11.60 kV. With the wheel off the ground, using a 46...

Re: Phaserunner not being read by PhaserunnerSuite

I would guess that either the cable itself is bad between the USB-serial converter and the TRS plug to the PR, or that something is wrong with the PR's serial port. The cable can be tested by connecting it's serial out to it's serial in at the TRS plug, and using a terminal program to verify all se...
