Brushless DC Motors: The Bonded Neo Advantage

Reduction of cost and cost volatility in rare earth magnets is a critical concern for the magnetics industry today. Molycorp Magnequench introduces MQ2 magnets, which are ideal for applications that require high performance at elevated temperatures. Unlike sintered neo magnets, MQ2 magnets provide excellent temperature stability without costly heavy rare earths like Terbium and Dysprosium.

A high density isotropic powder designed for the manufacturing of bonded magnets with superior magnetic properties. Based on a patented and cost optimized Nd-Pr-Fe-B alloy composition, it can be used as a cost effective alternative to MQP-B+-20056-070.

With rare earth elements reaching record prices last year, magnetic motor designers in 2012 have one question, what's the alternative? Designing with Dysprosium-free bonded neo.

Laboratory tests indicate that magnets using this technology can operate at 200°C for 1000 hours with less than 5% total flux loss.

Magnequench produces and sells its patented bonded neo powder for the manufacture of bonded magnets employed in A/C fan, refrigeration fan, circulation pump motors and in motors in personal appliances like electric shavers and vacuum cleaners.

We have leveraged our extensive melt-spinning knowledge to continuously push the boundaries of magnetic properties, manufacturing tolerances, and quality control within our industry.

MQA has substantially higher energy product and remanence than isotropic powders. It is also competitive with exisiting powders for anisotropic bonded magnets.
