Patent ID: 8564168

Claim:
An electric machine comprising: a stator; and a rotor lamination assembly configured and disposed to rotate relative to the stator; the rotor lamination assembly comprising: at least one lamination member including a body member formed from a material having a first yield strength, the body member including an outer diametric edge, a first magnet receiving member and a second magnet receiving member, each of the first and second magnet receiving members including a first end that extends to a second end, the second end of at least one of the first and second magnet receiving members being spaced from the outer diametric edge to form a first bridge portion having a first width, and the first end of the first magnet receiving member being spaced from the first end of the second magnet receiving member by a first bridge zone having a first thickness; at least one lamination section distinct from the at least one lamination member, the at least one lamination section including a body section having a first magnet receiving section and a second magnet receiving section, each of the first and second magnet receiving sections including a first end section that extends to a second end section, the first end section of the first magnet receiving section being spaced from the first end section of the second magnet receiving section by a second bridge zone having a second thickness, the second thickness being greater than the first thickness; at least one lamination element distinct from the at least one lamination member, and the at least one lamination section, the at least one lamination element including a body element formed from a second material having a second yield strength that is higher than the first yield strength; and at least one lamination component distinct from the at least one lamination member, the at least one lamination section and the at least one lamination element, the at least one lamination component including a body component having an outer diametric edge, and at least one magnet receiving component, the at least one magnet receiving component including a first end portion that extends to a second end portion, the second end portion being spaced from the outer diametric edge to form a second bridge portion having a second width, the second width being greater than the first width.
