“…Such motors have two excitations, namely, PMs and field windings. The hybrid excitation combines the high power-density attribute of PM motors and the better field weakening (FW) capability of woundrotor synchronous motors [3][4][5][6][7][8][9][10][11][12][13]. The performance of hybrid excited motors depends on the ratio of the PM flux to the total field flux.…”

In this study, we compare three designs of half-wave rectified excitation PM motors, possibly for use in variable speed drive applications. Each proposed motor has a different ratio of permanent magnet excitation to total field excitation (hybridization ratio). The hybridization ratios are selected based on the dominance of magnetic flux contribution to the air-gap by the permanent magnet or field winding excitation. In order to investigate the effect of hybridization ratio on motor performance, a comparison study has been conducted at base speed, low-speed and high-speed region. The comparison is performed using the finite element method.
