Abstract
Recently, a technique
field weakening of PM magnet
promising solution for the wide
the PM machines. This paper presents the concept of phase
swapping where different phases of the machine are
interchanged to achieve desired field weakening using
windings switching technique. Maxwell 2-D simulation
results are provided to validate the proposed concept on a
2-pole 24-slot machine for three different speed ranges.
