Abstract: In AC drives, independent variation of torque and flux is one of the renowned techniques due to its elementary control computation, easy numerical implementation, and robust operation ...

Abstract: The permanent magnet synchronous machines are currently widely used in various applications for their favorable parameters, such as high power density, low mass and volume. Permanent magnet ...

Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...

Permanent magnet motors, or permanent magnet synchronous motors (PMSMs), are currently the standard in electric vehicles. This motor design, often abbreviated as PSM, offers high power density, making ...

The high-energy-product neodymium rare-earth permanent magnet (RE-PM) was discovered in the early 1980s. Later, dysprosium doping emerged to provide reasonable RE-PM magnetization life by sacrificing ...

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 ...
