The challenge: A compact, cost-effective extra-small drive in a tiny installation space, consisting of an electric motor, planetary gear and coupling as
customer interface. The drive needed to be extremely robust in order to ensure maximum reliability under a continuous
axial load. Quiet operation
was also essential to allow discreet use by the patient.
The Bühler Motor solution: A customized, compact, efficient drive not bound to any platform. Cost-effective development was possible due to
the successful combination
of process and material expertise. In-house testing during the course of development meant that strength and smooth
running could be continuously monitored and perfected. The complete measurement of all components ensured that
our manually produced
drive units could be used for clinical studies. This therefore minimized the investment risks for an automated production line. Even during the
prototype/small series production care was taken to ensure that the process would be
as identical as possible to the processes in later large-scale
production. This also included control plans, process flow plans and the release strategy by means of batch documentation.
The close cooperation between the project teams and the local proximity to overall four involved partners made it possible to work
together smoothly and to meet tight timeline.
