PROBLEM TO BE SOLVED: To provide a drive control device for a motor capable of accurately calculating an interference voltage value even during a transient time.SOLUTION: The drive control device for a motor comprises: first and second low-pass filters 8 and 9 to which d-shaft and q-shaft current command values are inputted; first and second weighting means 10 and 11 for weighting output values of these low-pass filters, respectively; interference voltage calculation means 12 for calculating interference voltages of a (d) shaft and a (q) shaft from output values of the weighting means; and voltage command value calculation means 3 and 4 for calculating d-shaft and q-shaft voltage command values by subtracting the d-shaft and q-shaft interference voltages from d-shaft and q-shaft current command arithmetic values calculated by current calculation means 2. |
