ABSTRACT:
In a homopolar, switched reluctance, or interior permanent magnet motor, formed rotor laminations are employed to reduce eddy current losses in the pole faces and body of the rotor. The homopolar and switched reluctance motor lamination is comprised of a magnetic portion having a plurality of pole pieces extending generally radially outward from the core portion and forming a plurality of interpole spaces. Non-magnetic, high resistance segments are bonded between the pole pieces to minimize windage losses and increase strength. The non-magnetic segments may be thinner in the axial direction than the magnetic portion to prevent contact between stack laminations. Additionally, a gap may be left between the interior core portion and the non-magnetic segment to facilitate use of automated welding techniques. In the interior permanent magnet motor lamination, the non-magnetic segments perform the function of circumferential bridges, with or without restraining ligaments, to increase the rotor strength and speed capability and increase specific torque.
