PROBLEM TO BE SOLVED: To provide a control device for an induction motor capable of appropriately driving two rotors even when turning a vehicle.SOLUTION: A control device for an induction motor comprises: a motor 2 in which a first rotor 22 and a second rotor 23 are disposed on axial surfaces at both sides of a stator 21 while interposing a predetermined gap therebetween; and an ECU 5 which calculates target torques of the first rotor 22 and the second rotor 23 on the basis of a torque distribution of the first rotor 22 and the second rotor 23 and a target total torque that is required for the motor 2, and selects a drive frequency that is common for the first rotor 22 and the second rotor 23, on the basis of the target torques of the first rotor 22 and the second rotor 23 and rotation speeds of the first rotor 22 and the second rotor 23.SELECTED DRAWING: Figure 1
【課題】車両の旋回時であっても二つのロータを適切に駆動させることができる誘導電動機の制御装置を提供すること。【解決手段】ステータ21の両側のアキシャル面に所定のギャップを介して第1ロータ22及び第2ロータ23を配置したモータ2と、第1ロータ22と第2ロータ23のトルク配分と、モータ2に要求される目標総トルクとに基づいて第1ロータ22及び第2ロータ23それぞれの目標トルクを算出し、第1ロータ22及び第2ロータ23それぞれの目標トルクと、第1ロータ22及び第2ロータ23それぞれの回転速度とに基づいて、第1ロータ22及び第2ロータ23に共通の駆動周波数を選定するECU5と、を備える。【選択図】図1
