Abstract: A rotor for an axial flux motor and a method of manufacture includes a rotor core having a rotor hub with a plurality of spaced apart fingers radially extending from the rotor hub and forming a magnet pocket between adjacent fingers and into which a magnet is inserted, where the rotor core is formed of a plurality of layers of material arranged into a layer stack, with each layer having a set of primary fibers extending in a select direction that is a different direction from the set of primary fiber layers of an adjacent layer in the layer stack.

Abstract: A two-speed electric drive assembly for vehicles includes a main driveshaft driven by a first axial flux motor where the main driveshaft extends coaxially through a hollow assist driveshaft driven by a second axial flux motor. The main driveshaft includes a main gear that is continuously meshed with an intermediate gear on an intermediate driveshaft. A freewheel gear is mounted around the hollow assist driveshaft and can be selectively coupled and decoupled with the hollow assist driveshaft by a shift mechanism. The freewheel gear is continuously meshed with an intermediate gear on the intermediate driveshaft. Another intermediate gear affixed to the intermediate driveshaft is continuously meshed with an output gear affixed to an output driveshaft. The two-speed electric drive assembly can selectively switch between speed mode and torque mode without torque interrupt.

Abstract: A utility vehicle having a chassis frame extending along a centerline axis where the chassis frame includes a first side frame member and a second side frame member opposing one another about the centerline axis. A first drive mechanism is supported by the first frame member, and a second drive mechanism is supported by the second frame member. A first gearset assembly is coupled to the first drive mechanism, and a second gearset assembly is coupled to the second drive mechanism. A first axial flux electric motor is coupled to the first gearset and positioned between the first frame member and the first gearset, and a second axial flux electric motor is coupled to the second gearset and positioned between the second frame member and the second gearset. The first gearset and the second gearset are spaced apart from one another on opposite sides of the centerline axis thereby permitting each gearset assembly to be readily installed and maintained without interfering with the opposing gearset assembly.
