Comparison of Halbach Magnetized Brushless Machines


Comparison of Halbach Magnetized Brushless Machines Based on Discrete Magnet Segments or a Single Ring Magnet
This paper compares the air-gap field distribution, cogging torque, back-electromotive-force waveform, and efficiency of brushless machines having a Halbach magnetization produced by either discrete magnet segments or a single ring magnet. Results deduced from finite-element analyses are compared with measurements, and the performance of Halbach magnetized is compared with that of machines equipped with radially magnetized magnets
