ERS rotary modules

Specials Compact mechatronic module

Dec 1, 2015

SCHUNK has developed ERS rotary modules for rotary movements in the medium load range. The currently most compact mechatronic rotary module on the market is available in unit size 170 with a height of 66 mm, achieving a nominal moment of 5 Nm, and a maximum moment of up to 17 Nm. It is used for implementing flexible and compact system concepts. The core piece is a torque motor with a hollow shaft. It is light-weight and compact, and is absolutely wear-free, making it very reliable. It can endlessly turn up to 250 rpm to any intermediate position at a repeat accuracy of 0.01°. In contrast to rotary modules with a conventional servo motor, the ERS has no additional interfering contours and no elasticity. This long-lasting module from the company convinces with high acceleration, swiveling speed, and precision. On request, an integrated pneumatic holding brake ensures that individual positions can be reliably fixed.
