New Magnet-Free Electric Motor Needs No Maintenance
The new design also requires no rare earth elements, making it better for the environment.
German automotive parts manufacturer MAHLE developed a new highly efficient magnet-free induction motor that is more environmentally friendly to produce, is cheaper to manufacture than comparable motors, and is maintenance-free, a press statement from the Stuttgart-based firm explains.
The company says it has combined the strengths of various electric motor concepts in one product, allowing for an efficiency "above 95 percent at almost all operating points" — a level only achieved in Formula E racing cars thus far.
MAHLE explains that its "new kind of magnet-free electric motor does not require rare earth elements." This makes production better for the environment as well as bringing "advantages in terms of costs and resource security," the company says in its release.
