Abstract
A composite rotor for an electric motor includes an annular composite support plate extending radially relative a central axis of the composite rotor between an inner diameter defining a central opening of the composite support plate and an outer diameter, wherein the composite support plate includes a quasi-isotropic composite material, and an annular magnet assembly extending around the central axis of the composite rotor and coupled to a surface of the composite support plate.
Claims20
A composite rotor for an electric motor, the composite rotor comprising:
- an annular composite support frame comprising an annular composite support plate extending radially relative to a central axis of the composite rotor between an inner diameter defining a central opening of the composite support plate and an outer diameter, wherein the composite support plate comprises a composite material formed of a quasi-isotropic laminate having a plurality of separate plies of woven fabric oriented at non-zero angles to each other;
- and
- an annular magnet assembly extending around the central axis of the composite rotor and coupled to a surface of the composite support plate.
A composite stator for an electric motor, the composite stator comprising:
- an annular composite support ring extending radially relative a central axis of the composite stator between an inner diameter defining a central opening of the composite support ring and an outer diameter, wherein the composite support ring comprises a composite material formed of a quasi-isotropic laminate having a plurality of separate plies of woven fabric oriented at non-zero angles to each other;
- and
- an annular electromagnet assembly extending around the central axis of the composite stator and coupled to a surface of the composite support ring.
An electric motor, comprising:
- an annular composite rotor comprising an annular composite support plate and an annular rotor magnet assembly coupled to the composite support plate;
- an annular composite stator comprising a pair of annular composite support rings and a stator electromagnet assembly coupled between the pair of composite support rings;
- and
- an output shaft defining a rotational axis of the electric motor and extending through the composite stator and the composite rotor, wherein the output shaft is permitted to rotate about the rotational axis relative to the composite stator but is rotationally locked to the composite rotor;
- wherein the electric motor is configured to generate a magnetic flux between the stator electromagnet assembly and the rotor magnet assembly to drive rotation of the output shaft about the rotational axis.
