Abstract
An electrical machine with a ball race preloaded by elastic deformation of a bearing end plate as well as a method for manufacturing the same comprises a stator and a rotor with rotor shaft. The rotor shaft is supported via the ball race in the bearing end plates. At least one bearing end plate is embodied so that it can be elastically deformed in an axial direction and the preloading of the ball race is created by a preloading of the bearing end plate in the axial direction.
