PROBLEM TO BE SOLVED: To provide an electric motor that has a pressure sensor capable of detecting a pressure of an internal space, and thereby, that can reduce the number of work processes in an air-tightness test.SOLUTION: A motor 1 that has an internal space 5 sealed from an external space, comprises: a body part 2 having a first space 5a constituting an internal space 5, a stator part 11 housed and arranged in the first space 5a and having winding, and a rotor part 13 all or a part of which is housed and arranged in the first space 5a and that has an output shaft; a detector 3 that constitutes the internal space 5 and that has a second space 5b communicating with the first space 5a; a pressure sensor 6 arranged in the internal space 5 and that can detect a pressure of the internal space 5; and an output part 7 that outputs information on the pressure detected by the pressure sensor 6 to the outside of the motor 1.SELECTED DRAWING: Figure 2 【課題】内部空間の圧力を検出可能な圧力センサを有することで、気密試験における作業工程数を低減可能な電動機を提供すること。【解決手段】外部空間に対して密閉された内部空間５を有するモータ１であって、内部空間５を構成する第１空間５ａと、第１空間５ａに収容配置され巻き線を有するステータ部１１と、第１空間５ａに全部または一部が収容配置され出力軸を有するロータ部１３と、を備える本体部２と、内部空間５を構成すると共に第１空間５ａと連通する第２空間５ｂを有する検出部３と、内部空間５に配置され内部空間５の圧力を検出可能な圧力センサ６と、圧力センサ６により検出された圧力の情報をモータ１外に出力する出力部７と、を備えるモータ１である。【選択図】図２
