Electric motor for applications in cleanroom environment.

摘要

The present invention relates to an electric motor (1) for clean room environment applications. The electric motor (1) comprises a housing (2), a stator (3) firmly connected to the housing (2) and a rotor (4) rotatably mounted relative to the housing (2). The rotor (4) has a first end, a second end and an output shaft (6) protruding from the housing (2) at least at the first end of the rotor (4). Rotor or output shaft (6) are sealed by means of a seal relative to the housing (2) or against a further fixed part of the electric motor (1). According to the invention, it is provided that the rotor (4) is rotatably mounted in the housing (2) at the first end with an oil-impregnated sintered bearing (9), wherein the oil-impregnated sintered bearing (9) simultaneously with the rotatable mounting of the rotor (9) the function of the seal takes over.
