We recently published an article on the Power Electronics with the headline, “Unique Motor Uses Only Permanent Magnets – No Electric Power Required.” We received a firestorm of criticism that this ...

The leading German tech giants over at Mahle have developed an electric motor that doesn’t use permanent magnets. It has the potential of powering a wide range of vehicles, it’s highly efficient, and ...

By removing rare earths from the equation, these designs promise cleaner supply chains and more sustainable production.

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

MUNICH, Germany—ZF unveiled an electric motor that does not require magnets or rare earth materials, reducing reliance on mining in countries such as China and cutting manufacturing's carbon footprint ...

Magnets, typically using rare earth metals like neodymium, are found at the heart of most electric vehicle motors. It's nice to have a permanent source of powerful rare earth magnetism in your rotor, ...

There is a constant need and desire throughout the HVAC industry to spur innovation and create new products and ideas that can redefine the marketplace. In the realm of motors, the permanent magnet ...

There seems to be some confusion within the industry about the terms “permanent magnet synchronous motors” (PMSMs) and “brushless DC (BLDC) motors”. I’ve talked with several different application ...

The NEC defines a controller in a few different ways. In Art. 100, a controller is described as “a device or group of devices that serves to govern, in some predetermined manner, the electric power ...
