Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/176580
Kind Code:
A1
Abstract:
A motor control device (100) comprises: a step-down device (90) that comprises a DC-output-type power conversion device (3) having a first operation mode in which a first voltage (Vdh, Vpn) is output and a second operation mode in which a second voltage (Vdl) lower than the first voltage is output; a power supply device (5); and a control device (11). The motor control device (100) controls a motor (6) of a flying object. The control device (11) controls the power conversion device (3) in the first operation mode if the flying object is away from the ground, and controls the power conversion device (3) in the second operation mode if it is determined that flight information that is one or both of motor parameter information (sigmpc, sigmp, sigmpe) obtained in association with control of the motor (6) and environmental factor information (sigev) related to the flight altitude of the flying object satisfies a preset condition, or if an operation mode signal (msig) in which the second operation mode is selected on the basis of flight information during control of the motor (6) is received.
