Yeah people have claimed that 5 phases is better for eons but i haven't ever seen a dyno graph that proves it. I've seen some that prove otherwise though. I remember falco did this with a hub motor. And the thing performed less well than a crappy crystalyte of the same size. where is this imaginary...

so the one thing we know fer sure it's vowel averse.

yeah, you want odd number of phases, can't remember why exactly; mutual saturation i think. so the next odd multiple of 3 would be 9 phase to possibly use multiple existing 3 phase inverters. https://www.danatm4.com/blog/5-benefits-multi-phase-motors-inverters 5 Benefits of Multi Phase Motors Invert...

Interesting. BSA made a shiftable fixed/free 2 speed hub called the 'DP'. There were cables controls to both sides of the hub.

someone @BSA has a sense of humour.
i guess you need to when you're english with such tiny limbs.

i can't find any amp rating on that page so i don't know where that 6A number came from. however it does say the connector can accommodate up 12 AWG wire so would expect the contacts to meet the same circa 30A capacity. more of a concern for me would be that they aren't made for outdoor use. but the...

with state of duh art eh-aye it has to be not only self-driving but self-aware to be a true cybertruck

Garbage that is true. garbage is in a solid state. but that whole dyson & fiskar too... it's an ole'-fashioned space race. Fisker was originally aiming at 2023 production, but its scientists are making such rapid advances that the company is now targeting 2020. "We're actually ahead of where we exp...

dyson has always been a scrappy little company...

But , if it is like everything else with a “ Dyson” name on it,

it will suck hard.

I'd yell at marty for necroposting... 1] exactly wtf iz the problem with keeping related info together in the same thread rather than endless-lee starting a new one on the same topic?; who/what determined it bad netiquette?(sp.) I dunno what you consider the threshold for necroposting is, but i'd s...

In spite of the large majority of electronic components where their manufacturers specify in great details all the electrical characteristics, for fluorescent tubes, it...

looks like top geer's production budget is covered for the year.

presser... 4M and Montefibre will disrupt the carbon fiber industry by combining Montefibre’s ultra-large tow precursor and 4M’s low-cost carbon fiber production technology to produce the world’s lowest-cost industrial-grade carbon fiber. http://4mio.com/4m-carbon-fiber-and-montefibre-carbon-to-part...

I myself was a bit miffed almost 7 years ago when I ordered a new controller and stuff for CrazyBike2 that they didnt' tell me I could wait just a little bit and get one that had some better features for what was probably the same price. isn't that the american way? sell you the same thing over & o...

+1?? TF is the only ebike i've owned & ridden from 2005 to date. while the sine controller wuz a decade ahead any one else delivering silky smooth silent power, bike-like it aint when the battery runs out. it's why i've done a ton of reading & have such deep abiding interest in this subject. If I re...

yeah there's got to be more to it or there wouldn't be so many papers out there on trying to reduce it if it really was just zero sum. as a general rule of thumb, most techniques to reduce cogging are a compromise that come with some trade-off. you give up a little of something that you can live wit...

there's a good chance that if he had reformed the election rules like he promised the first go round it's entirely possible he wouldn't have won. i'm surprised how deep the blu cuts into bc. for all the noise the anti-pipe gang makes (and premier whoring-again) they make it seem like they speak for ...

Hub motors just don't have enough power, full stop.

in fact, they have zero power at full stop.

not out of the box in the least but rather ancient. first i ever heard of pulling the stator was the late 90's solar challenge that several solar car in-wheel motors sometimes incorporated. https://endless-sphere.com/forums/viewtopic.php?f=30&t=16345 6_41btVawMc IIRC that's exactly what the old Tida...

ah yes, you clearly did say lbs. right in the title even. that's how ingrained it's become when reading specs. don't bother to read past the number as specs are always metric by default. the d-motor itself is actually something just under 4kg without the internal controller. only 75% more than what ...
