Starting Torque of a Motor
2009-09-06 07:04:00 Dear all, How can we calculate the starting Torque required/experienced by an AC Induction Motor. How can we calculate the no load current that should be drawn by the motor (any thumb rule or a rough estimate). Of course one way is to de couple it and measure the no load current, but
What Sort of Torque Potential with Constant Force Springs?
2009-09-01 07:32:00 What torque could a chained array of custom constant force springs absorb and is there a loss in winding and unwinding or mechanical gain? Does it create a delayed gearing potential; such as by winding for thirty seconds at sixty rpm then allows 600rpm for 5 seconds with 6 spiral inner chor

HST Intl - all-electric Mustang with 1000 ft/lbs of torque and a 0-60 time
2009-08-15 20:51:00 HST International is still here... they changed their domain and didn't have the old one forwarded (dumb!). Go to: http://www.hstintl.com/ Be sure to download the brochure: http://www.hstintl.com/tjaarda_-evx.pdf Their announcement last year and demonstration of all electric Mustang (how about a Mustang with 1000 ft/lbs of torque and a 0-60 time of 3.9 seconds?) made headlines - as it should. This is the long term future of cars in general... and with the right kind of development electrics could have the same or more performance potential than gasoline powered cars. Let's face it, folks, a move to this technology is coming - and we need to learn how to master it. These folks mastered the art of building one, now lets see how they master the art of staying alive in this economy.

Question on torque
2009-03-24 09:02:00 Hi! I was just looking at this article at wikipedia on regenerative braking where it says that the maximum torque generated by the Flybrid flywheel is 18 Nm. You need about 10 Nm just to tear a piece of toilet paper, its a very small amount of force. 18 Nm works out to just 10 foot pounds or so.
