Abstract
A motor control device includes a second switch capable of connecting a negative bus to ground, a third switch of which one end is connected to a second power source section connected to the bus and of which other end is connectable to ground, a current detection section configured to detect a current value between a coil of a motor and the negative bus, and an insulation resistance calculation section configured to calculate an insulation resistance value of the motor based on current values detected by the current detection section when the third switch is opened and when the third switch is closed in a state in which the charge of a grounding capacitor is discharged in such a manner that a power supply is turned off by a first switch and the second switch is turned on for predetermined time, a voltage value of a capacitor, and a voltage value of the second power source section.
