Thermal decoupling for rotor shaft of electric asynchronous machine whose rotor shaft mounted about rotor axis, with mechanical coupling between rotor shaft and laminated rotor

摘要

The motor contains rotor shaft (2) rotary mounted about rotor axis (1) and cylindrical laminated rotor (3) mechanically coupled to rotor shaft by friction junction between shaft and rotor, at least partly. The junction contains local contact zones for partial contact with inner periphery of laminated rotor and/or outer periphery of shaft. Several coupling elements (4) are located between outer periphery of shaft and inner periphery of rotor to form mechanical coupling. Independent claims are also included for assembly of electric machine.
