摘要： A motor control device includes: a current detection portion provided to an inverter and detecting a current flowing to a motor due to a voltage generated across a current detection resistor, a timing measurement portion measuring a conduction pattern switching timing by the inverter and a current detection timing by the current detection portion, and a correction portion finding a correction current value using a current value detected by the current detection portion and the conduction pattern switching timing and the current detection timing measured by the timing measurement portion. The motor control device configured as above can enhance detection accuracy of a motor current.
