Sorry if this is a stupid question. EVs use single speed transmission because the AC motor has instant torque. But they still use a transmission, the motor turns gears that turn the wheels. My question is, why not just directly spin the wheels with the motor?
In: Engineering
Electric motors spin crazy fast. It’s easier and usually more effective to use gears to get a slower rotation and a “stronger” rotation.
Electric cars with actual gearboxes will also have more strength in the lower gears for hillclimbing and starting but still be able to spin the wheels really fast at higher gears.
