Flexible rotary modules
Whether for highly dynamic electronic assembly, freely positionable rotary indexing tables for assembly applications or powerful rotary actuators for heavy loads – the world’s most extensive line of mechatronic modules from SCHUNK, with more than 300 standard components, offers the right mechatronic rotary module for every dimension. The module features two integrated air feed-throughs as standard equipment. Available options include four electrical feed-throughs and the SIL2-certified absolute position measuring system. The SCHUNK ERD, which is available in three sizes with nominal torques of 0.4 Nm, 0.8 Nm and 1.2 Nm, can be used to implement space-saving, high-torque and high-speed assembly systems that also fulfill the stringent requirements of the machine directives.
The rotary module is driven by a brushless synchronous motor with permanent excitation. Its special geometry ensures high dynamics and acceleration. Also, due to the optimized air feed-throughs, pneumatic actuators connected to the module can be actuated more quickly. These two combined factors ensure short cycle times and high productivity. The absolute position measuring system eliminates the need for time-consuming reference runs during startup and after an emergency shut-down; also, the repeat accuracy is improved, with a specified value of 0.01 mm.
A large number of pairs of poles ensures that the module generates a high rated torque of up to 1.2 Nm even at low speeds. The module can be controlled for example using Bosch-Rexroth IndraDrive CS drive controllers.
