    Abstract: An electric machine includes a plurality of teeth separated by a plurality of slots positioned on an armature of the electric machine. Each of the teeth may include at least one bifurcation. A plurality of magnets may be arranged on a main field of the electric machine to form an axial array group. The magnets in the axial array group may be arranged in the main field with respect to each other to create a multi-stepped arrangement having a predetermined step angle. The step angle is determined based on the positioning of the bifurcations and the slots.

    Abstract: Electric machines with, and related methods for, improved fluid flow through the electric machines are disclosed. According to some implementations, an electric machine may include a central opening and a plurality of teeth facing inwardly toward the central opening. Slots may be defined between adjacent teeth, and a wedge may be disposed in one or more of the slots, partitioning the slots into a coils portion and an open portion. A gap may be defined between the stator core and the rotor. A fluid flow path defined from the gap and the open portions of the slots provide for improved fluid flow through the electric machine. Wedges disposed in the slots to maintain the coils into a packed state.

    Abstract: An electric machine system includes an electric machine and a companion device. The electric machine has a stationary member and a movable member that, by interaction of magnetic fields, at least one of moves relative to the stationary member or generates electricity when moved relative to the stationary member. One of the stationary member and the movable member includes a permanent magnet. The companion device is coupled to the electric machine to communicate mechanical movement with the movable member. In certain instances, the electric machine system has adaptations for operation of the electric machine system subsea and/or in a corrosive environment.

    Abstract: Divided magnet rotors R having a stepped skew rather than a helical skew are described. The stepped skew enables the use of straight magnet sections (44) that can be inserted into the rotor core notches (38) thereby eliminating the need to produce a helix from the rotor cage. The stepped skew is effective in decoupling stator slot order harmonics. In addition, the stepped skew rotor R includes, in some embodiments, open slots (22) so that the rotor is not subject to rotor bridge saturation.
