In order to increase the productivity of a system, the cycle time for the time-critical axis must above all be reduced. This is to be achieved not only with an increased acceleration torque for reduction of the dynamic time slices, but also through increased rigidity for improved transient response. The following example of a packaging machine shows that a premo advanced line BG3 with 20% higher acceleration torque and 30% more torsional rigidity with comparable energy requirement achieves a significant increase in productivity. The movement path of 50 mm in the time-critical axis is completed 50 ms faster, which corresponds to a production increase of 29%.

The investment costs for the drive train and the running operating costs can be positively influenced through socalled downsizing. The aim is to achieve lower energy consumption using a smaller drive and therefore a smaller servo controller for the same productivity. This solution here is a lower moment of inertia with, at the same time, higher rigidity. Example: Delta robot using a premo advanced line BG2, the same result is achieved as with the significantly larger motor of a market competitor. The high rigidity of the actuator together with the lower moment of inertia enables the use of a smaller motor. At 6.5 A, the current consumption of the premo BG2 is approx. 50% below that of a comparable product. This enables the selection of servo controller and supply module that are one level smaller, which involves significant savings potential in the 3-axis application.

In comparison with the proven TPM series, the new premo servo actuators exhibit significantly greater flexibility and performance potential. The interface to the machine can be designed in different versions. The interface to the servo controller offers almost unlimited connection options through the voltage range up to 750 V DC and the wide selection of analog and digital encoders. Regarding performance the premo actuator generation offers more torque and power at minimized space.
