Electric rotary drive module ERMB

Rotary module used as front unit with any rotation angle up to 360°

Freely positionable for rotation with loads of up to 15 kg
Also suitable for use as a small, stationary, numerically controlled rotary table

The benefits to you:

  • Position sensing/reference switch with inductive sensors SIEN-M8
  • Defining non-operational zones with sensing module
  • Large hollow shaft diameter for cabling and air feeds
  • Free definition of the acceleration and speed profile during rotation: protects the mechanical components when the end position is approached and minimises vibration in the system
  • Fast and flexible installation: mounting interfaces on all sides
  • Reduced load on moving units thanks to the compact design and use of aluminium
  • Fast project planning and design: compatible with the DGE and DGC in Festo's mechatronic multi-axis modular system, and standardised adapters and interfaces for linear axes and grippers
