PROBLEM TO BE SOLVED: To provide a motor controller for a vehicle air conditioner which recovers a reduced rotational speed of a motor without a sense of incompatibility.SOLUTION: At normal times, a microcomputer 32 uses as a target rotational speed, a command value input from an air conditioner ECU 82 and controls an inverter circuit 40 in such a manner that an actual rotational speed of a motor 52 becomes the target rotational speed. If a temperature of a substrate detected by a thermistor 54A becomes equal to or higher than a predetermined temperature threshold, the microcomputer controls the inverter circuit 40 in such a manner that the actual rotational speed of the motor 52 is reduced to a predetermined rotational speed, and if the temperature of the substrate becomes lower than the predetermined temperature threshold after the actual rotational speed is reduced, the microcomputer controls the inverter circuit in such a manner that the reduced actual rotational speed is accelerated to the command value with predetermined acceleration similar to a start-up time of the motor 52.SELECTED DRAWING: Figure 2

    【課題】低下したモータの回転速度を違和感なく復帰させる車両空調機用モータ制御装置を提供する。【解決手段】マイコン32は、通常時はエアコンECU82から入力された指令値を目標回転速度とし、モータ52の実回転速度が当該目標回転速度になるようにインバータ回路40を制御する。サーミスタ54Aが検知した基板の温度が所定の温度閾値以上となった場合には、モータ52の実回転速度を所定の回転速度まで低下させ、実回転速度を低下させた後に基板の温度が所定の温度閾値未満となった場合には、低下させた実回転速度をモータ52の起動時と同様の予め定めた加速度で指令値まで向上させるようにインバータ回路40を制御する。【選択図】図2
