And how much does such a 100 kW (136 hp) electric motor weigh, I wonder?

Such a motor should be sufficient for speedy propulsion of most sedans.

Most people do not realize that a gasoline engine's torque characteristics mandate that if you want strong acceleration up to highway speed, the engine is automatically capable of reaching around 150 mph (again, in a sedan). 150 mph might be relevant sometimes in Gernamy, but for most people 120 mph (or even less) would suffice. With an electric motor capable of 120 mph, 0-60 acceleration would probably be in the range of 6 sec!

Just another benefit of electrical propulsion...

The 50 kW version weighs 30 kg, so I would expect the 100 to weigh less than twice that.


Sorry whilst I just exclaim - "that's just bonkers!"...

Anyone see the JCB DieselMax...?

Well that go me interested in the horsepower/torque physics again...

It's great to see the next motor designs - ta Jim

I know! I saw it on their website myself. It's really great :-)

I believe some Ph.D. students at my university were working on something like this a few years ago, but what really matters, it that it is commercially available. I really like how they have demonstrated a massive increase in performance on another motor by using their power control system! While such a system may carry a premium right now in order to recoup the development costs, the fundamental cost is the production cost. And we all know which way the cost of electronics is going... That applies for high-power electronic components as well, according to my sources at my local engineering college (btw, by engineer, I mean M.Sc. or B.Sc - not train operators or what else you call engineers in the English language...)

Ahh, how I wish I had been more interested in electronics and had become a high-power electronics engineer... For every three engineers like that that retire here in Denmark, only one graduates from college, so interesting jobs are guaranteed! Plus, I personally feel that the future will be much more electric, mostly because all significant sources of renewable energy give electricity as output.

That's why this is good news, even if it is just technological evolution.


Ahh Thomas - "engineer" can be used for both like many words in the english language....

I take it you read about the EU-Russia meeting in Finland today? (20/10/2006)
It is related to this entire blog and this post also...


In this case/post - its a combination of electrical engineering / mechanical engineering and so on ... although the basics come from the science of physics and chemistry (particular a branch known as materials science - highlighted by the parameters "toughness" - with "lightness" desirable characteristics).

I work in chemistry (but in a multidisciplinary section of it) - which is "applied chemistry" but more modernly called "green chemistry"...

The good thing with that is that I can work on green (chemical) engineering as well as the fundamental chemistry. I only wish (and I advocate to those in a position) to introduce chemical engineering modules during the undergraduate education. Even just the basic parameters - unfortunately due to the scope of chemistry - this for me didnt come in until postgraduate courses!! Afterwards I began teaching myself more and more - and am still learning - its always good to discuss with professionally trained engineers however... but ultimately they need us too - scientists and engineers work in tandem!

My advice to you (or anyone interested!) is to study the fundamental sciences (or a branch that you like) then try to specialise as you go - but ensuring you keep your options open for later in your career. With the engineering this will come in later... but forms an important part of learning about applied-science.

It's a well established idea that:
When you learn applied-sciences - you put principle into context therefore improving the education process....

one reason I keep coming back to this blog!!!!

Here in the UK we have had worrying declines in the uptake of chemists (and all the other sciences and engineering) at our universities...

the common sense idea is to use the above to try and reverse the trend?

Ultimately, who is going to design the third and fifth "New Induction Motors"??? Or develop materials for them etc... This is a worry I have - and hopefully the EU will get "FRAMEWORK 7" up and running with out too much Euro-cratic bureaucracy!!!

Not that I am anti-EU at all... it's just too much talk and not enough action never helps instil faith in people...


Apologies for going off topic... btw

Royalties from patent rights on highly efficient motors, batteries, solar panels, control systems and associated materials and software is an ideal niche market for American firms and universities, if copywrights can be properly protected.

However, the world would only benefit when low cost mass production is done in China, India, Brazil, Mexico and other low labour cost countries, unless the process could be fully automated.


Datasheet and news New Induction Motor for Hybrid Vehicles:


Why bother with this motor? The Tesla roadster uses a 185 KW (248 hp) ac electric squirrel cage electric motor, 85 to 95% efficient that weighs 70 lbs! (check their web site). Car companies should strive to use this motor and A123 Systems high power lithium ion batteries. Combining this ac motor with batteries that can put out 4 hp per kilogram will produce cars with umbeatable power to weight ratios. Let's see who puts these two pieces together.


Here is a poll: Should hybrid vehicles stay out of the commuter lane if there is only one person in the car? I don't know about other states, but this is happening in California. Personally I think if I was one of the engineers that came up with the HOV lane idea I would have a fit at this political manipulation to encourage the purchase of environmentally friendly cars. It is a disadvantage to commuters, and an insult to the taxpayers who spent billions renovations making these HOV lanes. Here is a link to the poll: http://www.apopularitycontest.com/display_poll.php?ID=1


this is very good......
i am a 11th grade student in india . i am desigining a electric vehicile ..... i want more info about electric motors and yours motor ..... can you just call me my mobile no. is +91-9449069444


This is the future.. if only someone would make a decent looking usable car. They all look rubbish apart from Venture one and the 2 based on Lotus elise.
I'll design one for free.

There are 3 problems with most of the Green Vehicles.

1)They are so unatractive, use new untested technology or are too expensive.

2)The great mojority of cars during the rush hours have 2,3,4,5,6,7 ot more seats and carry only the driver. Need an inexpensive, attractive exciting single seat commuter vehicle with 100 mpg in traffic and speeds up to 100mph.

3) Use existing technology - unlimited range 100+mpg - attractive - 0 to 60 in 4 seconds - single seat vehicle - can be built today with off the shelf components for less than $ 5000.00 net cost - if every developer wasn't so concerned with getting rich off of a patent or license.

With today's technology, hybrid is the best option


This new induction motor seems great.

My friend recently got into a car accident and it has made me want to
get a safer car.

I'd like to know what cars have received an NHTSA 5-star rating for
both front and side impact tests. Not all cars have been rated by the
NHTSA, so equivalent top-score ratings from European agencies (such as
euroncap.com) are OK too.

I'm interested in cars manufactured between 1996 and 2003. For each
car, I'd like the year, make, model, and URL to supporting evidence.

great I needed I think the hybrids are the future of our planet right track.


You semi educated nitwits have not got a clue as to the difference even between ele tric, hybrid and elecromagnetic.
All must go back to class.


This device can be install between internal-combustion engine and transmission.

I wonder what the present situation is?

I lament the decline of this forum.


I am glad that scientists continue to work hard to improve and modify the electric vehicles for its betterment.
