Electrical machine

摘要

The invention relates to an electric machine, comprising a rotor (8; 50; 76) and a stator (9; 29; 77), wherein the rotor (8; 50; 76) and/or the stator (9; 29; 77) comprise at least one laminated core (2; 11; 32; 72) having a substantially rectangular cross-section, wherein the laminated core (2; 11; 32; 72) comprises a sheet metal strip (1), wherein the sheet metal strip (1) is wound in a coil shape.

主权项

1. An electrical machine having a rotor (8) and a stator (9), with the stator (9) having a winding (12) and at least one laminated core (2; 11) with a substantially rectangular cross section, characterized in that the laminated core (2; 11) has a sheet metal shaped strip (1), with the sheet metal shaped strip (1) being wound in the form of a coil, and that the stator has a support (15, 17) including separate first and second portions arranged radially within the winding (12) of the stator and positioned along an axis of the stator, wherein the first and second portions of the support (15, 17) have opposing faces with inter-engaging and alternating axially recessed portions and axially raised portions wherein the support has at least one receptacle (16) defined within the first and second portions of the support (15, 17), and with the prestress of the wound sheet metal shaped strip of the laminated core (2; 11) being set such that the laminated core (2; 11) is arranged in the receptacle of the support (15, 17) of the stator without play.
