Abstract
There is provided a solution for electrical insulation for an output shaft, tool and/or accessory driven by an electric motor, and the presence of the electrical insulation is also easy to verify. A rotor shaft assembly for an electric motor includes at least one section that is configured to extend in an axial direction of the rotor shaft assembly outside of a stator assembly of the electric motor, when the rotor shaft assembly is rotatably mounted inside the stator assembly. An electrical insulator is connected to the at least one section and the electrical insulator is configured to connect to an output shaft for connecting with a tool and/or accessory, or configured to connect directly to a tool and/or accessory to be driven by the electric motor.
