Hey everyone
I recently put together this blog post on how to estimate the torque of a brushless permanent magnet motor based on its Kv and current draw. It's probably nothing new to most of you on here but it might still be of interest all the same. If you have any questions or suggestions I...
Thanks for the link, that's an interesting read.
I may be wrong, but from the looks of it a Lynch motor is just a brushed axial flux motor with solid conductors for the armature and possibly more than three phases. While the wiki page does mention that earlier motors used ferrite cores it also...
I know i'm a little late to the conversation but I might be able to shed a little light on the topic. As was mentioned above, ferrite only makes sense for high frequency applications where minimising core losses are your main concern. This is because of its low saturation magnetisation, which is...
I'm in a similar situation to redorblack, very interested in picking up a 3210 at this price but waiting on free time and funds.
Neither of which i will have for at least 3 weeks.
So for now you can chalk me up as an interested party, but nothing more.
Thats great news. When the dust settles on this trike plan I will put an order in.
So far its look as though I will be after the motor, single stage 'eDrive', a mount (size not known atm) and if that wasn't enough, one of your sprocket adaptors.
So pretty much the whole package.
I'm holding...
Hello all
I'm trying to find answers to a couple of questions if anyone is able to help.
I'm having a little trouble trying to calculate the top speed for an electric trike project i'm planing. Unfortunately i'm a complete novice when it comes to most of this so bear with me.
In short, i'm...
Yep, like most things its only applicable up to a point in the real world. Unless your lucky enough to be cruising around on a polished concrete floor, a wider tire will no doubt help.
But short of modifying the frame, is it possible to put a wider tier on this particular trike?
Very true.
While on the topic of basic physics principles I should also bring up something else that bugs me. Traction is not proportional to tire size. If two tiers of different tread widths are placed on the same (perfectly flat) surface with the same weight placed on them (including tier...
I love that 100mm LED :D
I will have to add it to my ever increasing list of projects. Seeing as its connected to a wall socket I wouldn't be able to resist making it brighter with a 7xXP-G LED MCPCB from cutter.com.au.
Anyway, this might be appropriate seeing as there are quite a few trike...
wow what a read.. well its 4am here and I just finished trudging my way through all 70 odd pages of posts :shock:
At lest now I'm all up to date and more confident than ever that this setup is perfect for me.
Any chance on an update Matt? Have you sold many more drives in the last few months...
Heh, welcome to my world :D Greenspeed trikes are a blast and a lot easier to ride than a KMX I find, hence the price differences.
Just make sure you use your flag! Oh and I highly recommend investing in a bike horn of some description. They are very hand when trying to make your self...
Wow I must say, I find that poll result a little disturbing..
Having studied the topic both formally and informally I guess its easy to become disconnect with public opinion at large. :cry:
Or maybe its just that the public opinion in the US is a lot different to that here in Australia.
I might be able to point you in the right direction.
A friend of mine recently bought a recumbent trike off this bloke. Although he builds and sell's his own trikes he is also an official Greespeed dealer and their head R&D man, if i recall correctly. He seemed like a nice enough guy so I doubt...
In the mean time I stumbled across VRdublove's Channel on youtube. His vid's should keep my thirst for high powered trikes quenched for a little while at least :D
No crazy where spin on his version, however the title of his latest video did state it was only running at 40%.
Anyway, his...
