A direct drive means a gearless mechanical connection between motor and machine. This principle can be realized with revolving and linear motors as well. The gearless design has advantages for the simplification of the system as well as for the dynamic performance of the drive. Last but not least the energy consumption is reduced. The simplification leads to the integration of actuator and machine components. This brings a cost reduction as well as a reduction of the maintenance costs. Some practical applications are discussed.
