Abstract
A motor control device includes a temperature input unit that inputs a temperature of a motor and a control unit that performs control such that the control unit drives the motor by constant current/variable voltage control by lowering a power source voltage in a case in which the input temperature of the motor is equal to or less than a first threshold value and drives the motor by constant voltage/variable current control at a predetermined power source voltage in a case in which the temperature of the motor exceeds the first threshold value.
Claims6
A motor control device comprising:
- a temperature input unit that inputs a temperature of a motor;
- and
- a control unit that performs control such that the control unit
- drives the motor by constant current/variable voltage control in a case in which the temperature of the motor being input is equal to or less than a first threshold value and
- drives the motor by constant voltage/variable current control at a power source voltage being predetermined in a case in which the temperature of the motor exceeds the first threshold value.
