PROBLEM TO BE SOLVED: To provide a drive device for electric automobile capable of judging an irregular state of flow rate of lubricant oil to be supplied to a speed reducer and the like.SOLUTION: This drive device for electric automobile comprises an electric motor 1, a speed reducer, an oil supply mechanism and a rotation sensor Sb. The drive device for electric automobile has irregular oil supplying judgement means 55 for judging an irregular state of an oil supplying mechanism Jk. The irregular oil supplying judgement means 55 has engine speed calculation means 59 for calculating a motor speed in reference to a rotation angle detected by the rotation sensor Sb and flow rate detecting means 60 for detecting a flow rate of lubricant oil discharged from a pump of the oil supply mechanism. Further, the irregular oil supplying judgement means 55 has a judgement part 62 for judging irregular state of flow rate of lubricant oil in accordance with a prescribed standard in reference to the flow rate of the lubricant oil detected by the flow rate detecting means 60 and the motor speed calculated by the engine speed calculating means 59.SELECTED DRAWING: Figure 5

    【課題】 減速機等に供給すべき潤滑油の流量の異常を判定することができる電気自動車用駆動装置を提供する。【解決手段】 この電気自動車用駆動装置は、電動モータ1と、減速機と、給油機構と、回転センサSbとを備える。電気自動車用駆動装置は、給油機構Jkの異常を判定する給油異常判定手段55を有する。給油異常判定手段55は、回転センサSbで検出された回転角度からモータ回転数を算出する回転数算出手段59と、給油機構のポンプから吐出する潤滑油の流量を検出する流量検出手段60とを有する。さらに給油異常判定手段55は、流量検出手段60で検出された潤滑油の流量、および回転数算出手段59で算出されたモータ回転数から、定められた基準に従って潤滑油の流量の異常を判定する判定部62を有する。【選択図】 図5
