Abstract: A power system with a reliability enhancing battery architecture for electric motors adapted for use in an aerial vehicle. Individual batteries may be used to power a subset two or more motors in systems with six or more motors, for example. Each motor may be powered by two or more subsets of batteries, allowing accommodation for motor failure. With a failed motor in a vertical take-off or landing mode, power may be diverted to other motors to continue proper attitude control, and to provide sufficient thrust. With a failed motor a second motor offset from the failed motor may be powered down to facilitate attitude control.

Abstract: A vertical takeoff and landing aircraft includes a starboard wing, a port wing, first and second tilt rotors coupled to the port and starboard wings respectively, and first and second batteries. A pair of control surfaces are arranged on a first side of the mid-sagittal plane of the aircraft, the pair comprising a first and a second control surface. A first flight actuator is electrically connected to the first battery and a second flight actuator is electrically connected to the second battery. The first and second flight actuators are mechanically connected to the first and second control surfaces respectively.

Abstract: An electric motor comprises a rotor and a stator having a yoke. The yoke includes a plurality of teeth mounted to the yoke and being aligned substantially parallel to an axis of rotation of the motor, each tooth including a first radial end adjacent to the yoke and a second radial end extending from the yoke, a plurality of field coils, each field coil being wrapped around a tooth, and a coolant circulation path including a first coolant channel defined between adjacent field coils and a second coolant channel defined between adjacent field coils and between the first radial ends of adjacent teeth. A third coolant channel may be defined between adjacent field coils and between the second radial ends of adjacent teeth.

Abstract: A solid motor coil with conductive pathways as part of a unitary construction. The conductive pathways are separated by resistive insulating layers. The conductive pathways may vary in their location within the cross-section of the motor coil, which may significantly reduce eddy current losses. The solid motor coil may result in a higher packing factor than previous designs. The solid motor coil may reduce the eddy current loss per conductor, with commensurate reduction in peak temperature rise. An electric motor with solid motor coils provides improved heat conduction and improved efficiency, allowing for a smaller motor package at higher power levels.
