Abstract
A rotor of an electric rotation machine includes a shaft, a laminated core arranged coaxially on the shaft and configured to receive magnets or an electrical conductor, and a torque transmission element non-rotatably connected to a shank of the shaft. The laminated core includes a rotor end plate on an axial side thereof. The torque transmission element has a higher strength than the rotor end plate. 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. One of the rotor end plate and the torque transmission element includes the pin, and the other of the rotor end plate and the transmission element includes the through-hole. The pin is formed via pressing into material of the one of the rotor end plate and the torque transmission element.
