Performance of Halbach magnet arrays with finite coercivity

Journal of Magnetism and Magnetic Materials, 2016
Abstract A numerical method to study the effect of finite coercivity on the Halbach cylinder geometry is presented. Despite the fact that the analytical solution available for this geometry does not set any limit to the maximum air gap flux density achievable, in real life the non-linear response of the magnetic material and the fact that the ...

Testing of an in-wheel Halbach array motor

2020 International Conference on Electrical Machines (ICEM), 2020
This paper presents the testing of an in-wheel permanent magnet Halbach array machine developed for automotive traction. A machine with a Halbach array rotor is experimentally compared to results from a surface mount variant with the same magnet mass and the finite element analysis (FEA) simulations done during its design.
