Let's Talk - Permanent Magnet Fundamentals

Wondering what magnet material to select for your application? Attend our tutorial at the ITEC 2017 conference and learn more. Arnold's Dave Farnia will discuss the impact of magnet material selection on transformers as well as permanent magnet machines. Basic concepts for electrical steels and permanent magnets will be covered, as well as their impact on overall system performance. Dave will wrap it up with pricing trends in both permanent magnets and thin gauge electrical steels.

Overcoming Design Challenges in High Performance Motors



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.
