SCHMIDT® TorquePress 200
Torque-Power for Servopress
High-dynamic, powerful and low operation costs – these are the advantages by using a torque motor in the new SCHMIDT® TorquePress 200 with 200 kN nominal force and 500 mm stroke.
Torque motors are used for fast and precise move- and positioning tasks and make high torques available. Due to the hollow shaft design mechanical intermediate elements as gear, clutch or belt are not necessary. Especially in this range of performance the mentioned parts – operated under load – are subject to an accordingly high wear. Parts which are not required do not cause any costs and this reduces the service effort. Construction will be more rigid, this is very important in order to realize more dynamic motion-sequences in the assembly technology.
The very high torque of the SCHMIDT® TorquePress 200 allows very high forces without additional mechanical transmissions. The considerably higher speed constancy compared to conventional drives entails a higher machine precision.
In comparison to high ratio electric motor driven spindle presses the SCHMIDT® TorquePress 200 has an essential lower self moment of inertia and thereby a high dynamic. For this reason the run-up time from zero to working speed is very short. The noise remains remarkably low with all load conditions.
SCHMIDT® TorquePress 200 is permanent load stable due to its active temperature-controlled cooling, like all ServoPresses of SCHMIDT Technology. A mechanical overload protection becomes active in case allowable top force of 250 kN has been exceeded.
Further highlights are the highly precise, wear-free roller-guide of the ram, the integrated fail-safe force-stroke monitoring and a true closed loop force control integrated in the drive control (continuous force control).
The integrated two-channel safety technology according to category 4 allows the EC-type approval for complete systems, which is required for manual load work stations.

The ideal automation component
Driven by an entirely newly developed torque motor, the SCHMIDT® TorquePress 520 is the perfect press component for quick and high-precision applications. The new drive technology offers high press force capacity and at the same time low mass moments of inertia that considerably increase the precision of press force and positioning. In automation solutions the quality and the efficiency can thus be considerably improved.
High dynamic, low moment of inertia
In comparison to high ratio servomotors and gear motors the torque motors have a much lower moment of inertia and thus a high dynamic. The start-up time from zero to working speed is only about 100 ms.
Constantly high torque
Due to the high-pole design of the torque motor the maximum torque is already reached at a low speed.
Constant high speed
The speed consistancy is improved by a factor of about 10 compared to conventional drives which results in higher machine precision.
Compact and space-saving
Due to the flange size of only 160 mm and a total length of 1100 mm the SCHMIDT® TorquePress 520 allows the space-saving integration into automation systems and can be integrated with other automation components.
Fully integrated process data acquisition
The force and displacement measurement via an absolute measuring system takes place directly on the ram with a resolution of 0.1 µm. By consequently avoiding gears and other mechanical transmission components a nearly backlash-free construction is possible which in combination with the low inertia, satisfies the highest precision requirements.
The exchange of data via higher level control becomes more flexible and easier to realize. The user is free to choose: either to select predefined displacement profiles, or to control fully and flexibly the displacement positions, speed and dwell time by higher level control.
