When you think of electric motors, you usually think of magnets. But magnets are heavy, and good magnets can pose problems when you need lots of them. A technology called SESM (separately excited ...

Old's Electric Motor Is Important. Permanent magnets are a critical resource for renewables, as the generators in some wind turbines and motors in electric vehicles rely on them to run. A Floridian ...

The race is on to create an ebike motor that adds the least amount of weight and bulk as physically possible, disappearing ...

The inductive current transmission unit inside the rotor of the new e-motor design performs like standard electric vehicles’ permanent-magnet synchronous machines, which the supplier says ...

The video explained that most electric car motors require magnets made from rare-earth elements, which can be costly, both financially and environmentally, to extract. The rare-earth materials ...

Arguably, the machine that has most eased the burden of work for humans is the electric motor – a device that transforms electricity into motion. You can find these at the heart of every washing ...

Before this neodymium-iron-boron magnet came along in 1984, electric motors, generators, audio speakers, hard-disk drives, and the like had to make do with pricey samarium-cobalt magnets.

I2SM does not require any brush elements or slip rings. ZF has developed a magnet-free electric motor disparate to Separately excited synchronous motors. The motor is compact with maximum power an ...

Tesla will create a permanent magnet electric vehicle motor with zero rare earth elements in it, the company announced at its Investor Day today. Rare earth elements are a bone of contention in EV ...

Permanent magnet radial flux motors operate by using a donut-shaped stator that surrounds a rotor of outward-facing permanent magnets. Almost all electric motors in EVs are radial flux machines ...

Caught in the middle of the U.S.-China trade war is a Chiclet-size magnet that is vital to every new electric vehicle on ... from medical equipment to EV motors.
