Abstract: A motor unit, which drives a compressor unit, includes a stator, which generates a rotating magnetic field, and a rotor, which is rotated about a rotational axis by the rotating magnetic field at an inner side of the stator. A drive circuit unit is placed at the inner side of the stator such that a position of the drive circuit unit in a direction of the rotational axis overlaps with the stator.

Abstract: An actuator includes a rod, an electric motor to generate a rotational driving force on supply of electricity, an output shaft to output the rotational driving force of the electric motor to the rod, a feed screw mechanism, and a rotation prevention mechanism. The feed screw mechanism includes a female screw portion formed on one of the output shaft and the rod, and a male screw portion formed on the other to mesh with the female screw portion. The rotation prevention mechanism is configured to regulate rotation of the rod caused by the rotational driving force of the electric motor.

Abstract: In an aerial vehicle, a malfunction determiner determines whether there is a malfunction in one of thrusters of the aerial vehicle. A flight controller activates the thrusters, and controls the output of each of the thrusters. The flight controller deactivates, when it is determined that there is a malfunction in one of the thrusters as a malfunctioned thruster, the malfunctioned thruster. The flight controller deactivates a selected thruster in the thrusters; the selected thruster being paired to the malfunctioned thruster, and controls the active thrusters except for the deactivated thrusters in all the thrusters to make the flight attitude of the aerial vehicle stable. The flight controller controls the active thrusters to cause the aerial vehicle to land while maintaining the flight attitude of the aerial vehicle being stable.
