The first magnet is disposed between the lamination stack and the first pole piece, and each pole piece has an outer pole surface. The rotor assembly also includes a sleeve including an outer sleeve body disposed about the outer pole surface of each pole piece to retain each of the pole pieces with respect to the lamination stack, and a plurality of spacers extending from the outer sleeve body radially inward toward the shaft. The plurality of spacers includes a first and second spacer, and the first and second spacers are disposed between the first pole piece and the lamination stack to reduce flux leakage of the first magnet.
