| 1. A pole assembly suitable for use in a rotor, said pole assembly comprising:
a permanent magnet pole formed from a plurality of permanent magnet blocks stacked together;
a plurality of pole cap laminations, each said pole cap lamination having a first sidewall at least as long as a first dimension
of said stack of permanent magnet blocks, said plurality of pole cap laminations stacked and bonded together to form a pole
cap having a stack length substantially equal to a second dimension of said stack of permanent magnet blocks, said plurality
of pole cap laminations mechanically coupled to a first surface of said permanent magnet pole; and
a plurality of base plate laminations, each said base plate lamination having a first sidewall at least as long as said first
dimension, said plurality of base plate laminations stacked and bonded together to form a base plate having a stack length
substantially equal to said second dimension, said plurality of base plate laminations mechanically coupled to a second surface
of said permanent magnet pole, said plurality of base plates laminations further including a plurality of first base plate
portions having a first length and a plurality of second base plate portions having a second length.
