Torque Density Comparison of Axial and Radial Halbach Couplings
Electromagnetic Field Computation (CEFC), 2016 IEEE Conference on
This digests presents the closed form 3-D analytical equations for an axial and radial Halbach rotor magnetic coupling. The closed form equations give insight into the upper torque density limits of NdFeB based magnetic devices. The performance of the axial and radial coupling is compared.
