Abstract
A motor assembly having a stator assembly and a rotor assembly for an electric motor assembly is disclosed. The stator assembly includes at least two stator arms. Each stator arm including: a distal portion having an inner surface and a plurality of stator teeth spaced along the inner surface of each of the at least two stator arms, the distal portions collectively defining a stator opening, the opening having a longitudinal axis, and, a conductor portion located proximate to the distal portion, the conductor portion non-axisymmetric relative to the longitudinal axis of the opening; and. The rotor assembly is located in the opening proximate the stator teeth.
Claims19
A motor assembly for an electric motor assembly comprising:
- a stator assembly including:
- a first stator arm and a second stator arm, each of the first stator arm and the second stator arm including:
- a distal portion having an inner surface and a plurality of stator teeth spaced along the inner surface of each of the first stator arm and the second stator arm, and
- a conductor portion located proximate to the distal portion;
- and
- a third stator arm positioned between the first stator arm and the second stator arm, the third stator arm including:
- a mating portion,
- a conductor portion extending from the mating portion, and
- a distal portion extending laterally from the conductor portion, opposite the mating portion,
- wherein the distal portions of the first stator arm, the second stator arm and the third stator arm collectively define a stator opening, the opening having an axis, and
- wherein the conductor portion of each of the first stator arm and the second stator arm is non-axisymmetric relative to the axis of the opening;
- and
- a rotor assembly located in the opening proximate the stator teeth.
A stator assembly comprising:
- a first stator arm and the second stator arm, each of the first stator arm and the second stator arm including:
- a distal portion having an inner surface and a plurality of stator teeth spaced along the inner surface of each of the first stator arm and the second stator arm, and
- a conductor portion located proximate to the distal portion;
- and,
- a third stator arm positioned between the first stator arm and the second stator arm, the third stator arm including:
- a mating portion,
- a conductor portion extending from the mating portion, and
- a distal portion extending laterally from the conductor portion, opposite the mating portion,
- wherein the distal portions of the first stator arm, the second stator arm and the third stator arm collectively define a stator opening, the opening having an axis, and
- wherein the conductor portion of each of the first stator arm and the second stator arm is non-axisymmetric relative to the axis of the opening.
