Method for producing a rotor of an electric rotation machine,and electric rotation machine

A rotor of an electric rotation machine, comprising:

• a shaft;
• a laminated core arranged coaxially on the shaft and configured to receive magnets or a electrical conductor, the laminated core having a rotor end plate on an axial side thereof;
• and
• a torque transmission element non-rotatably connected to a shank of the shaft and having a higher strength than the rotor end plate;
• wherein the rotor end plate is connected to the torque transmission element via a pin extending into a through-hole and forming a frictional connection with a wall of the through-hole;
• wherein one of the rotor end plate and the torque transmission element includes the pin, and the other of the rotor end plate and the torque transmission element includes the through-hole;
• wherein the pin is formed via pressing into material of the one of the rotor end plate and the torque transmission element.

A method for producing a rotor of an electric rotation machine,

• comprising:
• providing a shaft, a rotor end plate, a torque transmission element, and a laminated core configured to receive magnets or an electrical conductor;
• forming a pin on one of the rotor end plate and the torque transmission element via pressing material of the one of the rotor end plate and the torque transmission element;
• introducing the pin into a through-hole on the other of the rotor end plate and the torque transmission element;
• connecting the rotor end plate to the torque transmission element by applying a pressing force to the pin in an axial direction thereof via a pressing element and applying a counter pressure force to the pin in an opposite axial direction via a counter pressing element such that material of the pin located axially between the pressing element and the counter pressing element is displaced radially and a force-fitting connection is produced with a wall of the through-hole;
• and
• then, arranging the laminated core coaxially on the shaft so that an axial termination of the laminated core is formed by the rotor end plate.
