CPC H02P 27/06 (2013.01) [B64C 39/024 (2013.01); B64D 31/00 (2013.01); H02M 7/539 (2013.01)] | 15 Claims |
1. A motor control device for controlling a motor of a flying object that takes off from a ground and flies, the motor control device comprising:
a power source device which outputs DC power;
a power supply device which converts the DC power to AC power and outputs the AC power to the motor; and
a control device for controlling the power source device and the power supply device, wherein
the power source device includes a power source, a DC-output power conversion device for converting output of the power source to DC power, and an output capacitor for smoothing output voltage of the DC-output power conversion device,
the DC-output power conversion device has a first operation mode for outputting first voltage and a second operation mode for outputting second voltage higher than the first voltage,
when the flying object takes off from the ground, the control device controls the DC-output power conversion device in the second operation mode, and
when the control device judges that flight information which is one or both of information of a motor parameter obtained along with control for the motor and information of an environmental factor relevant to a flight altitude of the flying object satisfies a predetermined condition, or when the control device has received an operation mode signal for which the first operation mode is selected on the basis of the flight information during control for the motor, the control device controls the DC-output power conversion device in the first operation mode.
