  • Publication number: 20210067081
    Abstract: A motor control device includes at least one power converter. The at least one power converter is connected between a DC power supply and a motor. The at least one power converter converts a DC electric power into a multi-phase AC electric power by operating a plurality of switching elements and supplies the multi-phase AC electric power to the motor. The motor control device calculates a command value for operating the at least one power converter to control electrical conduction to the motor. The motor control device determines an overcurrent fault when a value of a current flowing through the at least one power converter or a motor winding of the motor exceeds an overcurrent threshold value.

  • Publication number: 20210046974
    Abstract: Control circuits control inverter circuits provided in correspondence to the control circuits by a drive mode selected from a plurality of drive modes. A cooperative drive mode is for controlling a current supply to motor windings by a plurality of systems by using a value acquired from the other control circuit via communication. An independent drive mode is for controlling the current supply to the motor windings by the plurality of systems without using the value acquired from the other control circuit. A one-system drive mode is for controlling the current supply to the motor winding by one system without using the value acquired from the other control circuit. The control circuits set the drive mode to a cooperative drive mode when inter-computer communication is normal. The control circuits set the drive mode to an independent drive mode or a one-system drive mode thereby differentiating an output characteristic of a motor from that in the cooperative drive mode.
