Abstract:
(EN) Provided is a three-phase synchronous electric motor control device capable of improving rotor position detection accuracy when one three-phase synchronous electric motor is driven by inverters of a plurality of systems and also provided is an electric power steering device using the three-phase synchronous electric motor control device. The three-phase synchronous electric motor control device 3 is provided with: a three-phase synchronous electric motor equipped with a first three-phase winding 41 and a second three-phase winding 42; a first inverter 31 connected to the first three-phase winding; a second inverter 32 connected to the second three-phase winding; a first control device for controlling the first inverter on the basis of the rotor position of the three-phase synchronous electric motor; and a second control device for controlling the second inverter on the basis of the rotor position of the three-phase synchronous electric motor. The first control device estimates the rotor position on the basis of the neutral point potential of the first three-phase winding and the neutral point potential of the second three-phase winding.
