| Abstract |
Permanent Magnet (PM) machines have been developed
for numerous applications due to their attractive features
especially after the development of NdFeB magnets. However,
their complicated control lets the researchers develop new
machine structures with easy field control. New alternative PM
machine topologies with field weakening or hybrid excitation have
been introduced in the literature for years to eliminate the effects
of problems associated with the cumbersome field weakening
techniques used in conventional PM machines. This paper reviews
the field weakening of PM machines covered from machine’s
perspective. Machine structures and features of each structure are
clarified for both radial and axial airgap PM machines studied
thus far. |
