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.
Permanent magnet assemblies and electric machines are challenged to achieve maximum power density in a smaller, lighter package. Join us at the IEEE International Electric Machines & Drives Conference, where we'll take a closer look at the material technology and motor topology of two high speed applications.
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.
Permanent Magnets Dominate EV
Vehicle electrification is a growing market for rare earth magnets. Consumption of rare earth magnets in transportation is estimated to rise from 7,000 tons in 2015 to 17,000 tons in 2020. Government mandates to reduce pollution, as well as high gasoline prices, are driving users to purchase more environmentally friendly vehicles. Permanent magnet machines are currently the leading choice for high performance automotive applications. The rotor’s well-balanced magnetic field and the lower stator current requirement, paired with very strong positional control, result in a higher motor efficiency. Two common choices for electric vehicle applications are neodymium magnets and samarium cobalt magnets, and each has its advantages.
Every type of permanent magnet has a unique set of characteristics that can affect how is performs in various applications. When evaluating magnet options for your project, pay attention to the following:
