Vorwerk production line

Vorwerk - step by step - Production line for assembling DC carbon-brush motors

Innovation is a tradition at Vorwerk & Co. Since its founding in 1883, Vorwerk has always been able to predict customer requirements and changing market conditions and respond to them quickly. The upright vacuum cleaner developed in 1929 in response to the economic crisis of the time was considered a slow seller because of its rather unobtrusive design. Today, Vorwerk's vacuum cleaner division contributes more to the group's turnover than any other. The latest development from Vorwerk is a series of particularly compact, light DC motors (40% weight reduction compared with older models) which are particularly efficient and are used in the brush units of their vacuum cleaners.

In cooperation with itus Industrietechnik und Sondereinrichtungen GmbH, the item Building Kit System has been used to design a conveyor belt system which enables the motors to be assembled in an extremely economical and efficient process. The motors are assembled on a total of ten independent machines each with its own cycle time but all integrated into a single belt conveyor.

The assembly line begins with a work bench for pre-assembling the stators which are then attached to a workpiece carrier in the second operation. Next, the rotor is inserted in the stator using integrated force and path monitoring. The "B" bridge and its capacitors and contacts are preassembled at a different work bench.
