Electric machine for use in performance range of multiple megavolt amperes, particularly asynchronous machine, has rotor rotating about axis with rotor winding, which is arranged in rotor sheet metal body

摘要

The electric machine (10) has a rotor rotating about an axis with a rotor winding which is arranged in a rotor sheet metal body. An exposed winding head (16) is provided outside the rotor sheet metal body. A winding head is provided with a winding head restraint system (29) for absorbing the centrifugal forces. The retaining elements (20,21) are provided with safety mediums, which secure the retaining elements against unintended release or from flying away in the event of a fracture.
