Voltage required, amperage required, watts required (yes I know watts is voltage multiplied by amperage) and just as many specifications as possible. I plan to spin an alternator or two and ramp up the to the requirements with a class B amplifier. I would also like feedback to see if this is possible
EV hobbyists typically use DC brushed motors, series wound, with field coils. These motors are relatively inexpensive and easy to work with. Newer AC designs, discussed below, require much more complex power controller circuitry. * More cutting edge designs use AC motors. The Volt and Leaf use AC synchronous designs. The Tesla, and upcoming Prius models use three-phase AC induction motors. The synchronous motors use powerful permanent magnets, which require rare earth metals. The induction motors have the advantage of not needing permanent magnets or rare earths. All the AC designs are highly efficient, and lend themselves well to regenerative braking. * EV motors run anywhere from 24 volts up to hundreds of volts. 120 volt designs are popular today with EV hobbyists. 200-400 volt designs are more common in large auto company designs. Higher voltages reduce the current carrying necessity of the wiring, making thinner, cheaper wiring designs possible. * In operation, an EV motor may pull 3,000 to 50,000 watts of power. A horsepower is about 750 watts, so just take the rated horsepower and multiply by 750 to get an idea of the maximum wattages.
The DIY electric car community has been active for some years now, There should be quite a few active sites by now. In the early days, DC motors were prevalent, now just as in the Locomotive field, AC has taken over. DC motors and PM AC often posses full torque at zero rpm. There were some designs that used a motor on each wheel, along the lines of Locomotive practice. These usually require the addition of wheel slip detection, however. A little like the traction control used on current autos.
then go to google.motors used are dc brushed motors.
