thank u very much sir, iam very glad to know its[BMW] concept. sir iam 1 year mechanical student in SASTRAdeemed university in BTECH.course , so ilike to give...
Just a little hybrid could be better than the current hybrid technology. Spread the engine apart from transmission. Insert a motor with clutch on engine...
Hi Eric, You would need to decouple the motor/flywheel from the IC engine when the IC engine is off and the motor is running. Main question I see is what is...
ZF make a clutch system that incorporates a traction motor. It looks like a heavy duty clutch, the motor is 15 kW. They call it the momentum start module, I...
iam samrat i read all about ur mails please explain me in detail. iam a mechanical 1 year student in engineering college ilike 2 get information regarding...
Disregard my post. Popular Mechanics late issue describes a Honda hybrid as very close to my idea. It has a flywheel alternator - motor - starter - clutch...
OK, there are two main types of hybrids: parallel and series hybrids. In a parallel setup, the ICE and electric drives work together, help each other out - the...
there is a collection of links, manufacturers, the armes forces, who have developped series-hybrids... it looks like these are going to be the next generation....
The biggest problem you face is low speed torque requirements needed for regenerative braking. When you what specify a motor for a drive wheel application you...
The VolksWagen Lupo (available only in Europe since over 6 years now - since 99) consumes a little under 3 litres per 100 km. There are a couple of other very...
Just a note to some that are not into industrial equipment. It is now routine to use variable drives for AC motors that drive all kinds of equipment. Motor...
Ed Danzer, An acceleration recorder could provide you with data that could convert to braking torque. Per ads in sports car magazines, an acceleration...
The information from accelerometers, or brakes that I have reviewed, some from cars, one from a garbage truck, and truck brake testing show a wide variation,...
Eric... this is one of those big DUH's that happen all the time... It is sickening to me when people talk all the time and effort to convert a car to electric...
From Timothy... ... They're lighter, I'm thinking. Electric model airplanes use DC brushless with rare earth magnets. Maybe because AC is too complicated? UQM...
Well, learning from real-life applications - I'm referring to our Montreal subway system - the regenerative braking is only efficient from full speed down to...
A DC brush-less motor is an AC motor... when the models converted over to them the flight times quadrupled and the power to weight tripled... if you can't run...
Yeah well, I'm no expert... what I do know, is that you don't use a dimmer switch on an AC ceiling fan without burning it out... you would need a DC motor to...
DC ceiling fan's???? Dimmer switches work but chopping off the wave with AC... An AC ceiling fan works by using full wave AC... I think anyone who would tell...
Just calculate it using mass and acceleration - standard engineering formula. You can't calculate it based on your engine and car's acceleration, BECAUSE you...
This refers to a number of posts lately, all not inserted below due to length. My intent was not to complain about any use of any technology new or old. I did...
... you ... require. Hmm, the drives aren't all that fancy - the real money is in the FETs, where you are basically buying efficiency. I imagine for a road car...
Electromagnetism is the basis of all electric motors, and can only created by DC power. AC motors use their polarity change as a switching of magnetic ...
... True... ... NOT TRUE... it is the current flow not the form there of... DC means Direct current... AC is Alternating current.. Both are current through a...
Hi all, I've just been a member of this group for a few days but I'd like to throw something out for comments. In the 70's Mechanix Illustrated/ Quincy-Lynn...
Hi Stan, bravo for putting people on track. I honestly believe that, if their figures are correct, the car we are building in smallefficientvehicles will do...
Big problem is getting buyers. Check out: http://www.greencarcongress.com/2005/04/vw_abandons_its.html [Non-text portions of this message have been removed]...
I wonder if part of the problem in adopting ultralight, high-efficiency vehicles is safety. Just thinking about the VW prototype, and having lived in Germany...
