ROTOR OF ELECTRIC MOTOR, AND ELECTRIC MOTOR WITH ROTOR

To provide a rotor of an electric motor and an electric motor with the rotor, which have a technique for resolving the problem of a foreign matter existing outside the electric motor from entering inside of the electric motor in the conventional art.SOLUTION: A rotor 14 of an electric motor includes a rotating shaft 26 extending in an axial direction, and a foreign matter receiving hole 50 that is formed in a rotating shaft 26 so as to face and open a gap 44 between an end 22 in an axial direction of a stator of the electric motor and the rotor 14 and receives a foreign matter entering the inside of the electric motor through the gap 44. According to the present disclosure, since the foreign matter passing through the gap 44 can be received by the foreign matter receiving hole 50, it is possible to reliably prevent the foreign matter from entering the inside of the electric motor.SELECTED DRAWING: Figure 2 【課題】従来、電動機の外部に存在する異物が該電動機の内側へ進入するのを防止する技術が求められている。【解決手段】電動機のロータ１４は、軸方向へ延びる回転シャフト２６と、電動機のステータの軸方向の端部２２とロータ１４との隙間４４に面して開口するように回転シャフト２６に形成され、隙間４４を通って電動機の内側へ進入する異物を受け入れる異物受容穴５０とを備える。本開示によれば、隙間４４を通過する異物を異物受容穴５０に受容させることができるので、異物が電動機の内側へ進入するのを、確実に防止できる。【選択図】図２
