Electric vehicles are becoming an increasingly common sight for most people. Whether it’s seeing a shiny new Tesla lower the road, or hopping on a light rail train or renting an electric scooter to get from that train to your dwelling, EVs are everywhere.
One problem with electric motors is that due to the speeds at which they rotate, to become useful in most vehicles, they need a gear reduction gadget. I’d contact it a gear reduction motor tranny, but usually, these gearboxes only have one speed. This takes the 10,000 rpm from a drive motor and reduces the velocity at the tires while multiplying torque.
What if there were a motor that didn’t need to spin as fast as that to make enough usable power and torque to operate a vehicle a vehicle? If that existed, you could change all sorts of reasons for having electric car design. If you didn’t need a gearbox, you’ll save a good-size chunk of weight and, probably even more crucially, space.
With that space, you could increase the size of your battery pack, and with the reduced weight, you would improve all kinds of things like handling, range and acceleration.
