Electric motor and method for its production

摘要

An electric motor (10) for a machine tool or the like. The electric motor (10) is provided with a shaft (12) on which an encoder disk (15) is arranged. A first bushing (17) is provided and is connected to the encoder disk (15). The encoder disk (15) is arranged with a sliding fit on the shaft (12), and rests on a stop in the axial direction. A second bushing (18) is provided, which is arranged adjacent to and at a distance from the first bushing (17) on the shaft (12), and is arranged with an interference fit on the shaft (12). A compression spring (19) is arranged between the first bushing (17) and the second bushing (18) such that the first bushing (17) is pushed against the stop.
