Abstract: An example rotor includes a rotor yoke having an outer circumference and an inner circumference. The rotor further includes a plurality of rotor ribs on a surface the rotor yoke and extending between the outer circumference and the inner circumference. The rotor further includes a plurality of magnets, each of the plurality of magnets being disposed adjacent to and between two of the plurality of rotor ribs.

Abstract: A stator core segment for an axial flux electric motor includes a first lamination step having a first length, a first width, and a first thickness, and a second lamination step having a second length, a second width, and a second thickness. At least one of the second length, the second width, and the second thickness is distinct from corresponding ones of the first length, the first width, and the first thickness.

Abstract: A connector assembly comprises a connector and a temperature sensor. The connector includes a connector housing formed with a sensor slot, and a conductive terminal arranged in the connector housing. The temperature sensor is inserted into the sensor slot and is adapted to detect a temperature of the conductive terminal in the connector. The sensor includes a shell having a first sidewall in thermal contact with the conductive terminal, and a second sidewall opposite to the first sidewall. The second sidewall defines an interference fit portion extending from an outer surface thereof. The interference fit portion forms an interference fit with an inner wall of the sensor slot. A remaining portion of the second sidewall except for the interference fit portion is separated from the inner wall of the sensor slot by a predetermined gap. The sensor further includes a temperature sensing element arranged in the shell.

Abstract: An example apparatus for detecting loudspeaker faults includes a switch detector to detect that a loudspeaker fault detection switch is enabled. The apparatus also includes an audio receiver to receive an echo energy threshold and audio from a microphone in a test area. The apparatus further includes an audio analyzer to detect that the echo energy threshold is not exceeded by an acoustic echo in the captured audio. The apparatus includes a fault generator to generate a loudspeaker fault in response to detecting the acoustic echo does not exceed the echo energy threshold.
