Re: [Amc-list] ELECTRO-RAMBLER =revisited=

In theory, yes -- hook it right to the driveshaft or axle. But in practice, you need a hefty motor to get something heavy moving. So there's a compromise between motor size/weight/heat generated, and the current draw required. Seems it's better in the long run to use a transmission -- at least a two speed job as Andrew keeps mentioning. That's why I figure a BW OD would be a good, light, easy to operate trans. That's only if you can electrically reverse the motor though. And have an electric lock-oout for the OD, which won't work in reverse. That's easy enough to accomplish with a relay to cut power to the solenoid. Since multi speed automotive trannys are readily available and easy to use, may as well use a smaller motor and take advantage of all the gear reduction already there.

Aren't electric motors like steam engines? Maximun torque at 0 rpm?
Should be able to run the driveshaft off the motor. The electric buses here have
no tranny.
