Motor designers in markets such as aerospace, motorsports, automotive, and industrial are challenged to continually improve the efficiency of their high efficiency, high switching frequency applications. These applications demand the best magnetic materials, and Arnold L Type laminated magnets maximize performance under extreme conditions.
Following in the slipstream of the aerospace industry, automotive OEMs are increasingly turning to new materials and technologies to reduce weight and improve energy efficiency in their products. The use of magnet-based motor designs is one approach that is translating successfully to the automotive industry.
We’re excited to share that Arnold Magnetic Technologies is partnering with Ames Laboratory to improve the magnetic properties of Alnico for use in energy efficient traction-drive motors.
Arnold’s Aaron Williams will give a presentation at the
(TechCon) in New Orleans in October. The presentation will discuss permanent and soft magnetic materials that improve performance in motor and generators.
Gerhard Martinek, Application Engineer at Arnold Magnetic Technologies, will speak at the Designing Greener Magnetic Applications seminar in Grenoble, France. His presentation will explore materials and technologies that increase energy efficiency in motors, allowing them to run faster, hotter, and at smaller sizes. Read the abstract below.

Greetings from Rome, where we were in attendance at the Workshop on Magnetics and Metallurgy 2016 conference. This was a fantastic venue for us to share some of the research we have been working on our with our partners in industry.
Smaller Motors, Bigger Design Challenges
Permanent magnet (PM) motors for EV applications have unique design challenges. As electric motors become smaller and faster, designers must consider the potential effects of electrical drive frequencies, magnetic eddy currents, laminated steel core loss, mechanical stresses on the quickly rotating shaft (rotor dynamics), and electrical control of the motor through the inverter.
