Have you wondered of how an electric motor works in an electric car? Well, you are not the only one. GM has released a video to showcase its new permanent magnet electric motor on the new Chevrolet Spark all-electric car. The video gives a lesson in electric motor “101”.
There are two types of electric motors used in today’s hybrid and electric vehicles: permanent electric motors and induction electric motors. The permanent magnet electric motors can handle a heavy load at low speeds and can operate in long duration, which is suitable for all-electric cars. While the induction electric motors are designed to provide optimum operation at lower power levels and higher speed driving, but can only operate at a short duration. This is why it is more suitable for hybrid vehicles.
Currently, GM is working on the 85 kW (114 hp) permanent magnet electric motor for its all-electric 2013 Chevy Spark. GM is testing out the electric motor at its a pilot facility in Wixom.
“We’ve spent the past few years highlighting our in-house battery capability, which will play a significant role as one of our core competencies going forward,” said Larry Nitz, GM executive director of Vehicle Electrification Engineering. “Electric motor development and manufacturing is another area of expertise we’ll need as we expand vehicle electrification technologies to address the needs of our customers around the world.”
Anyway, if you don’t know much about electric motors for hybrid and electric vehicles, you can watch the fun video below.
