Green Motors
Electric motors are used to drive vehicles because they can be finely controlled, they deliver power efficiently, are mechanically very simple, and release almost no air pollutants where operated. Electric motors often achieve 90% conversion efficiency over the full range of speeds and power output and can be precisely controlled. Electric motors can provide high torque while an EV is stopped, unlike internal combustion engines, and do not need gears to match power curves. This removes the need for gearboxes and torque converters. Electric motors also have the ability to convert movement energy back into electricity, through regenerative braking. This can be used to reduce the wear on brake systems (and consequent brake pad dust) and reduce the total energy requirement of a trip, especially effective for start-and-stop city use.
Another advantage is that electric vehicles can have less vibration and noise pollution than a vehicle powered by an internal combustion engine.
