Re: [EVDL] Looking for help learning to build EV motor

Alan Brinkman:
:)  Thank you very much for the leads--much appreciated!

John Lussmyer:
I've asked to join the EVTech e-mail list and will look to do the same 
for the SEVA list.  Thank you, John, great suggestions.


Chris Tromley:
I'm new at this, so I don't yet know what I'm up against.  But my 
super-secret, tried-and-true formula is to learn, experiment, fail and 
repeat.  Add a generous dashes of patience and perseverance in equal 
measure and enjoy.  This recipe has served me well. :)


At this point, I expect to have learnings worth reporting on (positive 
or negative) late this year.  If you ping me in the November/December 
timeframe, I'll be happy to share the lessons I've learned.


Thanks again to everyone for your thoughts, advice and help.

Brad,

I read your message too quickly and thought..just get a DC motor from 
E-bay, a strong controller, and get on with the conversion...
Then I read your background.
Then I carefully re-read your message. Scratch built EV, not a conversion. 
Start with building a switched reluctance electric motor and software control.

The first time I heard of a Variable Reluctance motor was the EMB Lectra VR24 
electric motorcycle that Scott Cronk developed, manufactured and sold. Some of 
the web pages have been saved for fans of the motorcycle and technology.
http://www.electricmotorbike.org/index.php?page=lectra

There are several Scott Cronk's in technology and the arts but here is a short 
bio on the VR motor guy:
http://www.energymatters.net/scott-cronk.html

I would contact him directly as from reading about him and the Lectra project 
he seemed like a down to earth type of guy with a passion for his work and some 
smarts. I do not know him personally.

Good luck!

Alan

Hi Brad,



Specific SEVA members you should contact include Rich Rudman at Manzanita Micro, 
and Dave Cloud at Cloud Electric (although I understand>Dave may have recently 
moved, we both use to live in Woodinville).

Hey, everyone,

I am located in the Seattle, WA area (Woodinville, actually), and am
interested in learning to build and control my own switched reluctance
electric motor.  The long-term goal of the project will be to build an
EV from scratch (not a conversion), but since I do not have a hardware
background yet, I'm looking for someone willing to at least help me
take all my "unknown unknowns" to "known unknowns" ;).  From there, if
need be, I can tackle transforming those known unknowns into knowns on my own.

Initially, I'd like to build a tabletop motor so that I can practice
software control specifically of starting the motor, controlling regen
during deceleration and acoustics, and controlling speed.

If you know anyone able and willing to help, I would appreciate an
introduction.

Thank you!

All the best,
-Brad Gibson

--OR--

I've noticed Elon Musk has established a bit of a pattern of finding 
innovators whose ideas didn't fit the established system--Eberhard, 
Tarpenning, AC Propuslion for Tesla, Mueller for SpaceX.


If you know of someone building versatile, high-performance motors in 
his/her garage who might be willing to discuss a possible EV venture 
with someone with an entrepreneurial and software background (me), I 
would also appreciate an introduction.

You probably want to contact the SEVA list (Seattle Electric Vehicle 
Association)
and possibly joint the EVTech email list.

Re: [EVDL] Looking for help learning to build EV motor

[Chris Tromley via EV]

Brad,

I am someone who is most certainly NOT an expert in your field, but I try
to approach any problem by finding its borders first.  I do know that
switched reluctance (SR) motors are very enticing due to their simplicity
and therefore low cost, but they are mind-numbingly difficult to control
well.  And an EV is s very broad-spectrum application, so good control
under a wide variety of conditions is a necessity.

Several years ago I read an article on a new suite of SR motors that
boasted a new level of control, but they don't seem to have taken the
market by storm yet.

Seems to me you'll need a mountain of expertise in SR motor theory before
you start.  Because that's what others have had at their disposal and
haven't created an EV-suitable SR motor yet.  TI and probably others have
chips that are specifically designed for SR motors and they've devoted a
lot of development time to the application.

This is well-traveled ground.  I know this appears to be throwing cold
water on your plans, but in fact I'm hoping you have some new ideas that
might bring SR motors to EVs.  Do you?  Can you share?

Chris
