But what if you hold the axle firmly so it can't rotate and Spinning rotor has an axle running through the middle that you use toĭrive a machine. Metallic core that rotates inside it (called the rotor). Hollow, outer, ring-shaped permanent magnet that stays static (sometimes called the stator) and an How does a hub motor differ from an ordinary motor? Note the thick copper coils of wire that convert electric power from the battery into

Right: Take it apart and what you'll see is a bit like this brushless motor from a PC cooling fan. Photo: Left: The hub motor of an electric bike. Or chains, they build a motor directly into the hub of each wheel-so the motors and Instead of having one motor powering all the wheels using gears Latest electric cars and electric bicycles work a different way. Most electric-powered vehicles ( electric cars, electric bicycles, andĮlectric motor to power either two or four wheels. Through tightly coiled wire that sits between the poles of a magnetĪnd the coil spins around making a force that can turn a wheel and
Motors, you'll know the basic idea of turning If you've read our main article on electric How does a brushless DC (BLDC) motor work?.How does a hub motor differ from an ordinary motor?.Photo by courtesy of NASA Marshall Space Flight Center (NASA-MSFC). Though not exactly hub motors as such, each wheel was nevertheless powered by its own separate 10,000 rpm electric motor. Photo: One of the aluminum mesh wheels from NASA's lunar roving vehicle, an electric car used on the Moon in the early 1970s, with tires made from (compact electric motors built into each wheel) instead of engines. What if we could do away with the bulky, gasoline engine entirely andĭevote more room to the passengers and their cargo? That's one of theĮxciting possibilities that opens up if you use hub (in-wheel) motors Largely for historical reasons: they've always been built that way. Passenger zone-the most important part of a car for most of us-has
Have an engine at the front, a trunk at the back, and a passengerĬompartment stuck in the middle. But there's no real reason why a car has to We're so used to the idea of cars being, well, car-shaped, that we find any other body layout extraordinary.
