Abstract
A rotor for an electric rotating machine, in particular a synchronous machine includes a shaft that can rotate about an axis of rotation, and at least one pole shoe. In order to improve vibration properties, the pole shoe includes a pole shoe body and a pole shoe sheet metal which rests on a radially outer surface of the pole shoe body.
Claims21
A rotor for an electric rotating machine, such as a synchronous machine, said rotor comprising:
- a shaft mounted for rotation about a rotation axis;
- and
- a pole shoe connected to the shaft, said pole shoe including a pole shoe body and a pole shoe metal sheet, said pole shoe metal sheet lying on a radially outer surface of the pole shoe body and connected at a plurality of connection points to the pole shoe body, said pole shoe metal sheet having curvatures and/or grooves so as to be configured flexible between the connection points at least in an axial direction.
A rotor for an electric rotating machine, such as a synchronous machine, said rotor comprising:
- a shaft mounted for rotation about a rotation axis;
- and
- a pole shoe connected to the shaft, said pole shoe including a pole shoe body and a pole shoe metal sheet, said pole shoe metal sheet lying on a radially outer surface of the pole shoe body and comprising at least two layered individual metal sheets.
An electric rotating machine, such as a synchronous machine, said electric rotating machine comprising a rotor which includes a shaft mounted for rotation about a rotation axis, and a pole shoe including a pole shoe body and a pole shoe metal sheet, said pole shoe metal sheet lying on a radially outer surface of the pole shoe body and connected at a plurality of connection points to the pole shoe body, said pole shoe metal sheet having curvatures and/or grooves so as to be configured flexible between the connection points at least in an axial direction.
An electric rotating machine, such as a synchronous machine, said electric rotating machine comprising a rotor which includes a shaft mounted for rotation about a rotation axis, and a pole shoe including a pole shoe body and a pole shoe metal sheet, said pole shoe metal sheet lying on a radially outer surface of the pole shoe body and comprising at least two layered individual metal sheets.
A method for manufacturing a rotor, said method comprising:
- forming a pole shoe metal sheet with curvatures and/or grooves to impart flexibility;
- placing the pole shoe metal sheet on a radially outer surface of a pole shoe body;
- connecting the pole shoe metal sheet at a plurality of connection points to the pole shoe body to form a pole shoe, such that the curvatures and/or grooves extend between the connection points;
- and
- connecting the pole shoe to a shaft mounted for rotation about a rotation axis.
A method for manufacturing a rotor, said method comprising:
- forming a pole shoe metal sheet by placing at least two layered individual metal sheets in superimposed relation to impart flexibility;
- placing the pole shoe metal sheet on a radially outer surface of a pole shoe body to form a pole shoe;
- and
- connecting the pole shoe to a shaft mounted for rotation about a rotation axis.
