Abstract
A control apparatus, which controls a drive motor that drives a rotor installed in an electrical aircraft, instructs the drive motor to selectively operate in at least two motor-control modes. The at least two motor-control modes include a flying motor-control mode for causing the electrical aircraft to fly, and a cleaning motor-control mode for cleaning the rotor. The control apparatus controls, in the cleaning motor-control mode, the drive motor such that a rotational frequency of the drive motor is lower than a predetermined human-audible frequency range.
Claims10
A control apparatus for controlling a drive motor that drives a rotor installed in an electrical aircraft, the control apparatus being configured to:
- instruct the drive motor to selectively operate in at least two motor-control modes that include:
- a flying motor-control mode for causing the electrical aircraft to fly;
- and
- a cleaning motor-control mode for cleaning the rotor;
- control, in the cleaning motor-control mode, the drive motor to rotate at a predetermined rotational frequency that is lower than a lower limit of a predetermined human-audible frequency range;
- and
- control, in the cleaning motor-control mode, the drive motor such that the predetermined rotational frequency is lower than 20/A Hz where A represents a positive integer indicative of the number of blades of the rotor.
