The invention relates to an electric motor (1) with at least one bearing (4), by means of which a shaft (8) or an axle of the electric motor (1) is rotatably mounted. During the operation of the electric motor (1), sound is produced which can be detected by means of a sound sensor (12), wherein a sound source can be formed in particular by the at least one bearing (4). The electric motor (1) is equipped with a sound chamber (13) which is delimited by multiple delimiting surfaces. At least one of the delimiting surfaces comprises a sound surface. The sound surface is made of a surface of the bearing (4) or a surface of a body which guides sound to the surface. The sound sensor (12) is arranged in the sound chamber (13) and is designed so as to detect sound (15) transmitted from the sound surface to the sound sensor via air. The electric motor (1) can be part of a ventilator and/or a system with an analysis unit. In the first case, an impeller is provided which is connected to the rotor of the electric motor (1). In the second case, the analysis unit has a communication interface, via which measurement values of a sound sensor (12) and/or prepared measurement values from an electronic sensor unit (16) can be received by the analysis unit. The analysis unit is designed to then analyze the measurement values and/or the prepared measurement values.
