    Abstract: A self-cooling fan in configured with a vent feature that draws air into a fan housing and over a heat sink to dissipate heat generated by the motor and/or control unit. The self-cooling fan has a conduit with an attached end opening that couples with a cooling zone within the fan housing and extends along a portion of the fan blade(s). A vent feature is an opening in a conduit, at or near the extended end of the conduit, that allows air to exit the conduit. A vent feature may be a venturi feature. A venturi feature creates a vacuum within a conduit via outer diameter blade velocities interacting with venturi geometries when the blades are rotating, further promoting the drawing of air into the fan housing. A cooling channel allows air from outside of the fan assembly to enter into a cooling zone where a heat sink is configured.

    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 include teeth arrayed around the motor axis. Each tooth has a tooth face oriented towards the rotor. Multiple of the lamina forming each tooth are exposed at the tooth face and are configured to extend axially and radially to the tooth face. The stator phases magnetically interact with the rotor to drive rotation of the rotor on the motor axis.

    Abstract: A high efficiency transverse flux motor fan utilizes a transverse flux motor that can provide torque to drive fan blades at a reduced weight over conventional induction and brushless DC motors. A fan incorporating a transverse flux motor may be a residential ceiling fan or high volume low speed fan. Transverse flux motors are ideal for these applications as they have a higher efficiency at low revolutions per minute. A transverse flux motor may have a stator utilizing a ring shaped lamina that has extending members that form a coil channel. A lamina may be a unitary piece of material that is formed from a sheet of metal, thereby providing a very lightweight stator assembly. An exemplary fan may provide an airflow efficiency of more than about 236 L/s*W, (500 CFM/watt), an essential airflow density of more than about 2.36 L/s*g, (5 CFM/gram) and a power density of about 150 W/kg or more.

    Abstract: A grease inhibitor is disposed about a rotating shaft of an electric machine. The grease inhibitor is configured to inhibit flow of grease towards electromagnetic components of the electric machine along the shaft. The grease inhibitor includes an inner member that rotates with the shaft and that interfaces with a static component to form the grease inhibiting interface.

    Abstract: An electric motor includes a rotor and a stator that includes a plurality of coils arrayed along a rotational axis of the rotor. The rotor is potted with potting compound. The stator is potted with potting compound. Each coil of the stator is electrically connected to a power source to receive operating power from the power source. The coils are powered to cause the stator to electromagnetically drive rotation of the rotor on the rotational axis.

    Abstract: A transverse flux motor is formed by a stator portion and a rotor portion. The stator portion includes one or more phase assemblies formed by flux ring plates axially bracketing coil wire windings. The flux rings include teeth that magnetically interact with circumferentially opposed and adjacent teeth to form flux paths transverse to the axis of rotation of the rotor assembly.
