Abstract: An electric motor includes a rotor and a stator formed by a plurality of stator phases. The stator phases include coils that extend fully about the motor axis of the motor. The stator phases further includes flux rings disposed on opposite axial sides of the coil and that are joined by axial returns. The stator phases electromagnetically drive rotation of the rotor on the motor axis. Stator segments are formed by one or more stator phases grouped together. Rotor segments are formed by one or more rotor phases grouped together. Motor segments are formed by one or more stator segments and one or more associated rotor segments. Motor segments are stacked along a shaft to form the electric motor.

Abstract: A fluid moving apparatus includes an electric motor having a rotor and a stator and a propeller. The rotor rotates relative to the stator on an axis to generate a rotational output. The rotational output is provided to the propeller to power the marine propulsion apparatus. The stator includes one or more coils configured to power rotation of the rotor. The one or more coils extend circumferentially around and can be coaxial on the axis. A portion of a housing of the motor extends into the aquatic environment to facilitate heat dissipation.

Abstract: An electrical machine includes a rotor with a rotational axis, a coil arranged circumferentially with respect to and fully encircling the rotational axis, and a stator assembly. The stator assembly includes first and second lamination stacks comprising associated pluralities of laminae, the stacks being arranged circumferentially with respect to the rotational axis on opposing sides of the coil for conducting magnetic flux. The stacks are configured with gaps generally radially through the laminae thereof, defining separate circumferential segments in each laminae, to prevent creating a continuous electrical circuit around the rotational axis in the segments. Each laminae has a connecting ring spaced radially from the segments, and beams connecting the segments to the ring as a unitary piece. Back return elements extend axially between the stacks to provide a flux path therebetween, and are positioned circumferentially between adjacent parts of the beams and radially between the segments and the ring.

Abstract: Electrical machines, for example transverse flux machines and/or commutated flux machines, may be configured to achieve increased efficiency, increased output torque, and/or reduced operating losses via use of laminated materials, for example laminated materials configured with cuts and/or segmentations. Segmentations may also assist with manufacturability, mechanical retention of components, and the like.
