摘要： PROBLEM TO BE SOLVED: To drive and control a motor with high accuracy by identifying an induction voltage coefficient of a permanent magnet synchronous motor accurately regardless of the size of a load torque. SOLUTION: A control device includes a current detector 4 which detects a current value to an inverter 2, a power estimator 9 which estimates a power value to be supplied to the motor 1 by using the current value detected by the current detector 4, a current estimator 11 which estimates a d-shaft current value and a q-shaft current value of the motor 1 by using the current value detected by the current detector 4, a Ke identification calculator 12b which identifies the induction voltage coefficient of the motor 1 by assigning the power value estimated by the power estimator 9 and the d-shaft current value and the q-shaft current value estimated by the current estimator 11 to a predetermined equation when each of a plurality of speed commands showing different speeds is output each, and an output voltage command calculator 15 which calculates the voltage of each phase to be added from the inverter 2 to the motor 1 by using the induction voltage coefficient identified by the Ke identification calculator 12b.

摘要： PROBLEM TO BE SOLVED: To correctly detect a phase current of a motor even if a shunt current is sampled in a fixed timing. SOLUTION: A control unit 10 includes a voltage command generation section 13 that generates a first voltage command value for each phase of a motor 1 using a value of a current in a shunt resistor 23 of an inverter 20; a three-phase voltage modulation section 14 that generates a second voltage command value for each phase by adding an adjustment amount, which is a difference between an intermediate phase command value of a middle voltage among the first voltage command values for respective phases and a middle level of a carrier signal, to the first voltage command value for each phase; a PWM control section 15 that outputs a switching signal to each switching element of the inverter 20 at an intersection between the carrier signal and the second voltage command value for each phase; and an A/D conversion section 11 that samples a value of a current in the shunt resistor 23 in a timing in which a voltage value indicated by the carrier signal becomes the middle level of the carrier signal.
