Luvata Pursues EV Market to Apply Hollow Magnet Wire in Direct Cooled Stators 

September 27, 2022 Editorial Staff 0

Direct-cooled motors with hollow conductor stators offer several advantages over the indirect-cooled motors currently used in EVs, says Luvata of Finland, which has been making copper hollow conductors for more than sixty years. Adoption of the technology, typically used in more exotic applications such as superconduction, high-energy physics and magnetic resonance imaging, into mass-market electric vehicles faces considerable technical obstacles, however, and much higher cost than conventional magnet wire.  […]

Big Magnets Require Big Deliveries 

September 6, 2022 Editorial Staff Comments Off on Big Magnets Require Big Deliveries 

Some magnets are heavier than others. Handling them can be a challenge, in this case tackled by Wimmer Maschinentransporte of Germany. They can take longer to make, too. Two recent examples from the engineering and manufacturing facilities of Bilfinger Noell are the 13-ton monster PERC magnet shown, in part, above, and a superconducting “Wiggler” recently delivered to Brookhaven National Laboratory.  […]

McCrometer Seals the Deal on the Achilles Heel of Magnetic Flow Meters 

July 14, 2022 Editorial Staff Comments Off on McCrometer Seals the Deal on the Achilles Heel of Magnetic Flow Meters 

Magnetic flow meters can have an Achilles heel in their design but engineers at McCrometer have sealed the deal through careful manufacturing techniques and the use of fusion-bonded epoxy to prevent contamination with drinking water, wastewater and industrial streams which the instruments are measuring. The company received new NSF certifications for its Ultra Mag and Dura Mag electromagnetic flow meters recently, marking further testament to the robustness of the materials and manufacturing process, as well as the integrity of its quality team.  […]
