AML has pioneered an advanced manufacturing process for permanent magnets known as the PM-Wire process. This novel technique introduces significant flexibility in both the shapes of magnets and the direction of their magnetization, which substantially broadens the possibilities for designing permanent magnet motors and generators.

A key advantage of the PM-Wire process is its ability to utilize materials with low coercivity. For example, the process facilitates the use of curved magnets, which minimizes the demagnetization field. Additionally, it enables the implementation of configurations with lower remanent flux density, specifically in a single-piece Halbach array arrangement.

Through extensive research and development, AML has demonstrated that PM-Wire magnets manufactured from materials such as samarium-iron-nitride (SmFeN) and manganese-bismuth (MnBi) offer considerable value to the motor industry. These advancements hold promise for providing an alternative to sintered NdFeB, which suffers from an unstable supply chain.

The discussion will cover the steps involved in producing these magnets and highlight how the process introduces flexibility in both magnet shapes and the direction of magnetization providing unique value for the motor industry.

The presentation will also feature practical examples of motor designs that leverage the unique capabilities of PM-Wire magnets. These case studies will illustrate how the process enables innovative approaches in permanent magnet motor and generator design, contributing to the advancement of the motor industry and offering viable alternatives to traditional approaches.
