Permanent Magnet Rotor Flux Linkage Control Through Direct Axis Field Amplification

IEEE Open Journal of Industry Applications
Permanent magnets are popular for electric vehicle rotors due to their high energy density, making them excellent candidates for high-torque and high-speed machines. The downside of a permanent magnet machine is the inability to regulate the rotor field,

Air‐gap field prediction in tubular doubly sided surface magnet machine using Bessel–Fourier series

IET Electric Power Applications
2‐D air‐gap magnetic field distribution is the essential prerequisite of electrical machine analysis. Because of the natural periodicity of rotary machines, Fourier analysis is a suitable choice for air‐gap field prediction.
