Abstract
An electric motor is fastened to a machine, such as a piston pump. For fastening the electric motor to a positioning device, the invention proposes embodying a motor housing with T-shaped fastening elements, whose crossheads are bent into a circle and which engage blind bores in the positioning device and are retained in the blind bores by a calk.
Claims22
An electrical unit having an electric motor and a machine that can be driven by the electric motor, the electric motor and machine being connected to one another, the electric motor (12) has a fastening element (64), which engages an undercut (70;
- 76) of the machine (14) from behind, wherein after the electric motor is positioned against the machine (14), the undercut (70) is formed by a calking, so that the undercut (70) thus exerts an initial tension on the fastening element (64).

An electrical unit having an electric motor and a machine that can be driven by the electric motor, the electric motor and machine being connected to one another, one of the electric motor (12) and the machine (14) having one or more fastening elements (64), and the other having one or more undercuts (70, 76), wherein the fastening elements (64) engage the undercuts (70;
- 76) from behind, and wherein, after the electric motor is positioned against the machine (14), the undercuts (70) are formed by calking, so that the undercuts (70), as they are formed, thus exert an initial tension on the fastening elements (64) to hold the electric motor (12) and the machine (14) tightly together.
