new motor design

[Jack Riggi]

    well I tryed to cut & paste a storey about a new motor design but it came back saying(the message's content type was not explicitly allowed) so I will waste some more of my time & try to type what I read about it.     One New Zealand manufacturer uses what it calls advanced fabrication techniques for electric motors. The process involes moving electronics from printed cicuit boards to custom silicon devices, extensive use of polymers & ceramics, & avoiding stamped laminations. The manufacturer says it bringss revolutionary technology (as in assembling cell phones) to the industry. They claim the motors will be physically smaller, robust, & highly effcient & will surpass currently available motors. The company says its existing motors consume 80% less energy, & use 30% less copper & 80% less steel then conventional designs. Applications will focus on refrigeration, ventilation equipment & vending machines.                              Does this sound like it would be good!

Hi Jack,

 From the sound of it they are making small motors that won't work for
the main motor in an EV.

Can you paste in the web site address so we can read it ourselves?

Thanks!

Sounds like Wellington Drive Technologies. See http://www.wdtl.com/ and
http://www.wdtl.com/motor_design.php

They actually claim "efficiency rates up to 80%", which is hardly
impressive. Looks like all their motors are < 500 Watts.

1. Please read the EVDL guidelines here :

http://www.evdl.org/help/index.html#conv

In particular, please note point 6.

Sorry, but it sounds like ad-speak to me.  I suspect that the above was
written by someone with a  marketing degree, not an engineering degree.

The main obstacle to successful commercialization of EVs is not the motor,
it's the battery.  Sure, it's possible to eke out a tiny bit more efficiency
in motors, but the current designs are really quite highly evolved.  

I'm not an engineer, but IMO, there's  more to be gained in reducing vehicle
mass and rolling resistance, and improving aerodynamics.

Research is being done on advancing motor materials. See this article for example:

http://www.greencarcongress.com/2007/10/plastic-bonded-.html

Whether the advances make enough economic sense to make it to market is another matter.

motor on a table fan is 15 to 30% efficient.  A DC motor driving windshield
wipers or such, maybe 60% ?????   For an EV sized motor, yes, we expect
more, but for really small ones, it might actually be an improvement.
