Schunk Develops New Rotary Mechatronic Modules

Schunk Develops New Rotary Mechatronic Modules

Added to MTDCNC by MTDCNC on 07 August 2015

Compact powerhouses with integrated intelligence


For many years, the SCHUNK high-performance rotary modules have been successfully used in laboratory, research and industrial applications. As the competence leader for clamping technology and gripping systems, SCHUNK has now enlarged its mechatronic product line with the new series SCHUNK PR 2, PDU 2, and PSM 2.


These new systems offer three particularly compact, intelligent drives with a very compact performance that are optimised for robust industrial applications. The complete power electronics of the modules have been fully integrated into the modules, so no external controller is needed and cabling as well as the potential for error are minimized.


Fast and easy commissioning


The modules are available in three standardized unit sizes. Equipped with standardised plug connections, the units can be quickly and easily connected. Optionally, control is done by Profibus (up to 12 Mbit/s) or CAN-Bus (up to 1 Mbit/s). For commissioning and use with PC, the SCHUNK motion tool and modules are equipped with a USB connection. This enables them to be manually addressed by means of an easily adjustable rotary encoding switch.


Initial module movements can be manually realised via a DIP switch. The status of each module can be seen on an LED display. Due to the integrated Harmonic Drive, the PR2 rotary module and the PDU 2 drive for linear axes achieve enormous torques between 16Nm and 184Nm - depending on the module size. The directly driven PSM 2 module can be used for fast movement of small masses. It is compact and achieves a torque of 1.8Nm up to 4,320rpm. Position, speed and torque of all the three modules can be individually controlled. An incremental encoder ensures high position and repeat accuracy. The integrated holding brake is activated as soon as the target position is reached. For evaluation of the sensor signals, the module is equipped with two digital inputs.
