Unit consisting of a motor and a piston pump

The invention relates to a unit comprised of a motor and a radial piston pump, whereby the motor has a rotating rotor with a motor shaft (3) for driving the piston of the piston pump. In addition, an eccentric component is fastened to the motor shaft (3). The invention is characterized in that the motor shaft (3) and the eccentric component (5 and 6) are produced as bent sheet metal components. The bent sheet metal components result in a lighter weight construction of the shaft-eccentric component unit, and economical manufacturing methods can be used in order to produce said unit.
