Abstract

A motor driving device of the present invention is a motor driving device that incorporates so-called vector control of controlling a current applied to a motor winding in accordance with the position of a rotor. The motor driving device receives the input of a duty command value from a host controller via a command input port, for example. The motor driving device obtains a current command or a speed command as a command value such that the input duty command value is equal to the duty of a drive pulse output from an inverter. Then, the motor driving device performs vector control based on the obtained command value.
