COMPONENT FOR AN ELECTRIC MACHINE

The invention relates to a component for an electric machine, wherein the component is designed as a rotor, comprising a shaft (1), an active part (3), which surrounds the shaft (1) in the circumferential direction and which is arranged concentrically to the shaft (1), and at least one web (4), which is connected to the shaft (1) and the tip (5) of which points radially outward from the shaft (1). The invention further relates to a component for an electric machine, wherein the component is designed as a stator, comprising a housing (2), a hollow cylindrical active part (3), which is arranged within the housing (2), and at least one web (4), which is connected to the housing (2) and the tip (5) of which points radially inward from the housing (2). The invention further relates to a method for assembling such a component or such an electric machine and a service method for such a component or for such an electric machine. The problem addressed by the invention is that of enabling an economical and reliable assembly of rotors or stators. This problem is solved in that the component has at least one respective connecting element (6) and at least one respective fastening element (7), wherein the active part (3) has in each case one groove (8) open radially outward or radially inward for accommodating a respective first end (9) of the respective connecting element (6) and the respective tip (5) of the respective web (4), wherein the respective groove (8), the respective web (4), and the respective connecting element (6) are designed in such a way that an interlocking connection of the respective web (4) and of the respective connecting element (6) to the active part (3) can be obtained by fastening the respective connecting elements (6) in the region of the respective second end (10) of the respective connecting element to the respective web (4) by means of the respective fastening element (7).
