1. An adhesive-reinforced rotor for a rotary electric machine, comprising:
a stack of rotor lamination layers constructed of a magnetic core material, each of the rotor lamination layers having inner axial surfaces collectively defining a set of rotor openings through the magnetic core material;
one or more reinforcement blocks constructed of a non-magnetic, non-metallic, and electrically non-conductive material, wherein the one or more reinforcement blocks are disposed within a respective one of the rotor openings; and
a polymer primer/adhesive layer having a bond line thickness of less than 1 mm, wherein the polymer primer/adhesive layer is disposed between the one or more reinforcement blocks and the inner axial surfaces of the rotor lamination layers, the polymer primer/adhesive layer and the reinforcement blocks have a tensile strength of at least 50 MPa, and a modulus of elasticity of the reinforcement blocks is at least three times greater than a modulus of elasticity of the primer/adhesive layer.
