    Abstract: A flying device includes a plurality of rotary vanes, a motor element serving as a driving source for each of the plurality of rotary vanes, the motor element driving and rotating a main shaft of the rotary vanes, and a drive circuit. The motor element includes a stator, a rotor, and a pair of bearings. The stator includes a stator core having an annular yoke and a plurality of teeth projecting inward from the annular yoke, and stator windings wound respectively around the plurality of teeth of the stator core. The rotor includes a permanent magnet of a cylindrical shape located inside the stator core via a gap, the permanent magnet being positioned counter to the plurality of teeth, a rotor yoke in contact with a cylindrical inner wall surface of the permanent magnet, and a shaft pivotally supported at an axis of the rotor yoke, the shaft being connected to the main shaft. The pair of bearings pivotally support the shaft to allow the shaft to rotate freely, and are located respectively on both sides of a direction of a rotating shaft of the rotor. The permanent magnet has anisotropically arranged magnetic poles, and a number of the magnetic poles is P representing an even number. The permanent magnet is configured such that the rotor yoke is smaller in weight than the permanent magnet. The drive circuit controls a stator current supplied to the stator windings.

    Abstract: A motor controller of an unmanned aerial vehicle (UAV) is optimized to improve operation of the UAV. The motor control optimizations include controlling a motor of a UAV to reduce an operating temperature of the UAV, reducing an amount of latency or jitter resulting from motor operation, and applying a smoothing filter for motor operation. For example, controlling a motor of a UAV to reduce an operating temperature of the UAV can include using a temperature model for the unmanned aerial vehicle or an operating temperature measurement to determine a current operating temperature and comparing that current operating temperature to a threshold. If the threshold is exceeded, settings of the motor are adjusted to cause the motor to operate in a manner that reduces the current operating temperature.

    Abstract: A quadcopter pressure washer that may facilitate cleaning objects and surfaces in remote areas. The quadcopter pressure washer includes a tubular airframe, a plurality of rotary motors, a battery and controller, a pair of antennae, a signal receiver, a nozzle, a turret, a high-pressure hose, a pressure washer, a direct current or a DC power source, an alternating current/direct current or a AC/DC converter and a 120V AC power source. The quadcopter pressure washer also includes an operator control panel include additional a pair of antennae that extend upward in a programmable position from the operator control panel to transmit or receive any suitable electromagnetic signals. The additional pair of antennae utilizes state-of-the-art Doppler radar technology in electrical communication with the battery and controller. The operator control panel includes a signal emitter positioned in front of the operator control panel.
