摘要 |
The present invention employed a motor control device including: current sensors which detect currents in each phase of a three-phase motor; a coordinate conversion device which computes a d-axis actual current and a q-axis actual current in dq-coordinates from phase currents of three phases based on detection values of the current sensors; a voltage instruction computation device which computes a d-axis voltage instruction and a q-axis voltage instruction based on a deviation between a d-axis current instruction and the d-axis actual current and on a deviation between a q-axis current instruction and the q-axis actual current; a target phase current computation device which computes target phase currents for each phase from the d-axis current instruction and the q-axis current instruction; and a current difference computation device which computes, for each phase, a current difference between the phase current and the target phase current. |
