Low end torque is one thing an electric motor should have lots of. A series wound motor (like one in your electric drill) create highest torque when stalled. An induction motor ( clocks, pumps, anything that is basically A.C. only ) generate very little low end torque, with maximum torque occurring at ~90% of no-load rpm's. I remember an article in a Popular Science of a few year ago. This fellow had an electric car with a gas turbine that recharged the batteries whenever they needed it. One of the things that impressed the reporter type the most was the LOUD screech, blue smoke and the black left on the driveway when the inventor pulled out..... (hopefully the blue smoke was not from the windings!). Kevin -- Kevin Szabo watmath!wateng!ksbszabo (Elec Eng, U of Waterloo)
