PROBLEM TO BE SOLVED: To upgrade reliability against water entering the inside of a motor.SOLUTION: A motor for electric power steering systems in accordance with the present invention is a motor for electric power steering systems to be disposed below a rack shaft of a vehicle. The motor includes: a magnetic circuit unit that generates a rotary torque; a case that forms a storage space in which the magnetic circuit unit is stored; a water passage formation unit that forms a first water passage linked to the outside of the case and not passing through the storage space; and a water sensor that is disposed in the water passage to detect moisture.SELECTED DRAWING: Figure 3

    【課題】モータ内部に侵入した水に対する信頼性を向上させることである。【解決手段】。本発明に係る電動パワーステアリングシステム用のモータは、車両のラック軸よりも下方に配置される電動パワーステアリングシステム用のモータであって、回転トルクを生じさせるための磁気回路部と、前記磁気回路部を収納する収納空間を形成するケースと、前記ケースの外部と繋がっておりかつ前記収納空間を経由しない第1水路を形成する水路形成部と、前記水路内に配置されかつ水分を検出する水センサと、を備える。【選択図】 図3
