摘要： Embodiments of a modular motor assembly are disclosed. In some embodiments, a motor comprises a plurality of modular magnetic units, where each of the modular magnetic units includes at least one rotor and at least one stator. The motor further comprises a plurality of structural segments each adapted to support a stator of a corresponding one of the modular magnetic units, where each of the structural segments interlocks with a next structural segment to form a stack. A method of manufacturing a motor includes arranging a selected number of modular magnetic units, coupling the selected number of modular magnetic units to a shaft, coupling the selected number of modular magnetic units to respective structural segments, and forming electrical connections to apply three-phase voltage to stator windings of the modular magnetic units.

摘要： At least an output shaft angle associated with an output shaft is initialized to a known value where the output shaft is coupled to a motor shaft via a set of one or more gears. A direction of rotation associated with the motor shaft is determined using a plurality of discrete Hall sensors in the motor and the output shaft angle is updated using an incremental value and the direction of rotation.

摘要： One or more converters are selected from a plurality of converters to enable where there is a plurality of energy storage modules electrically connected together in series. Each converter is electrically connected to a corresponding energy storage module. The selected converters are enabled where in response to being enabled, an enabled converter converts an input, from its corresponding energy storage module, at a first voltage level into an output at a second voltage level and the outputs of the enabled converters are electrically combined to produce a combined output. The combined output is compared against a desirable operating region defined by an upper threshold and a lower threshold. In response to the combined output being outside of the desirable operating region, the number of enabled converters is adjusted.

摘要： A first measurement of a magnet that rotates is received from a first set of Hall sensors in a first component. A second measurement is received from a second set of Hall sensors in a second component where the first component and the second component are in a plane that is parallel to an axis of rotation associated with the magnet. An angle associated with the magnet is determined based at least in part on the first measurement and the second measurement.

摘要： A coupled battery and motor controller thermal management system is disclosed. In various embodiments, a motor controller and a heat sink are coupled thermally to a battery. At least a portion of waste heat generated by the motor controller is transferred to the thermal mass of the battery during at least a first mode of operation in which a relatively low amount of ambient air flows through the heat sink.

摘要： A lift fan position lock mechanism is disclosed. In various embodiments, a position lock mechanism includes a ring structure having a first surface, the ring structure including one or more detents defined in the first surface of the ring structure. For each detent, the lock mechanism includes a stationary magnet coupled fixedly to the ring structure at a location adjacent to the detent. The lock mechanism further includes a rotating magnet assembly comprising a magnet of opposite magnetic polarity to at least one of the stationary magnets and a mechanical stop structure of a size and shape to fit into a corresponding detent and engage mechanically with a surface defining at least one extent of said corresponding detent when the rotating magnet assembly is in a locked position.

摘要： A conductor in composite is disclosed. In various embodiments, an electrically conductive structure, such as an electrically conductive metal, is sandwiched between insulating material and two or more layers of fiber reinforced composite material, to form a stack that is used to form a composite structure that includes the electrically conductive layer. The layer may comprise an electrical line, trace, bus, etc. to conduct electricity from one location to another within the composite structure, such as to connect a battery or other power source at one location to an electrical load at another location.

摘要： A lift fan includes a stator which is configured to output a magnetic field. The lift fan also includes a first housing which in turn includes a blade, a second housing, and a magnet array. The magnet array is coupled to either the first housing or the second housing and the housing, which is coupled to the magnet array, rotates in response to the magnet array responding magnetically to the magnetic field output by the stator.

摘要： A magnetic spring input device is disclosed. In various embodiments, an input device as disclosed includes a manual input structure movably coupled to a base assembly; and a non-stationary magnet fixedly coupled to the manual input structure; a stationary magnet coupled to the base assembly in a manner that is fixed with respect to at least a first input axis of the input device, the stationary magnet being coupled to the base assembly with a first magnetic pole having a first magnetic polarity is oriented opposite a corresponding magnetic pole of the non-stationary magnet having the first magnetic polarity, in a position that is adjacent to but offset from the non-stationary magnet when the manual input structure is in a neutral position. The non-stationary magnet is coupled to the manual input structure in a position such that movement of the manual input structure about or along the first input axis of the input device brings said poles have said first magnetic polarity within sufficient proximity to generate a repulsive magnetic force.
