摘要

An electric motor with a housing (3), stator, rotor and shaft (6) comprises a unit (2) sealing the rotor space (7) from an outer space (8) that may have damaging substances. The seal has an elastic disc (9) of constant thickness, with a central recess with a counter disc touching the shaft that is closer to the disc than the disc thickness.
