Abstract
A motor control device for a motor including first and second winding sets, includes: first and second inverters; and a control unit that controls the first and second inverters by differentiating a magnitude of current flowing through the first winding set and a magnitude of current flowing through the second winding set, or by restricting an output voltage of the second inverter so as to reduce a first output voltage from the first inverter to the first winding set when the first output voltage is higher than a first upper limit voltage.
Claims20
A motor control device for controlling a motor including a first winding set and a second winding set, the motor control device comprising:
- a first inverter connected to the first winding set and supplied with electric power from a first power supply unit;
- a second inverter connected to the second winding set and supplied with electric power from a second power supply unit;
- and
- a control unit that controls the first inverter and the second inverter by differentiating a magnitude of current flowing through the first winding set and a magnitude of current flowing through the second winding set, or by restricting an output voltage of the second inverter, so as to reduce a first output voltage as a voltage to be output from the first inverter to the first winding set when a voltage to be output from the first inverter is higher than a first upper limit voltage determined based on a first maximum output voltage.
