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; ...

The study, led by Xianguo Gui，takes into account multiple nonlinear factors in the process of motor performance calculation. The new analytical model incorporates both main and leakage magnetic flux ...

NORD offers IE5+ motors in sizes 71, 90, and newly released, size 112, extending the power range from 0.5 to 15.0 hp.

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 ...

The Nano Materials Research Division at the Korea Institute of Materials Science (KIMS), led by Dr. Tae-Hoon Kim and Dr. Jung-Goo Lee, has successfully developed a groundbreaking grain boundary ...

Rare earth (RE) magnets have revolutionised the properties and applications of permanent magnets. They offer many advantages, and have drastically increased flux compared to traditional magnets with ...

“The ‘critical state model’ has had continued success since circa 1963. One of its rock-solid predictions is that in order to magnetize a piece of bulk superconducting material to its maximum ...

Rather than trying to secure alternative sources of rare-earth materials, Vimag is attempting to eliminate magnets from ...

The EC 40 brushless dc motor uses neodymium permanent magnets and has a stainless-steel housing with welded flanges. It has a very flat speed/torque gradient (about 3.6 rpm/mNm), a mechanical time ...
