The swivel arm module rotaryARM can be used for any assembly, handling, packaging, palletising and further applications that require a fast and precise automation solution. Optionally it is available with an additional NC-turning axis for the gripper. The new generation of swivel arm and turning axis of the rotaryARM can be rotated endlessly. This is made possible by an integrated rotary feed through for pneumatics and electrics. This also saves an additional energy chain. Additionally the system is very stiff and has low own weight including motors and absolute encoders.
Features
- NC-swivel arm module with optional turning axis
- Endless rotation with swivel and turning axis
- Large working area with compact dimensions
- Short cycle time by overlaying speed of swivel arm and linear axis
- Rotary feedthrough for pneumatics and electrics integrated in the swivel arm, thus no additional energy chain necessary
- Servo motors with absolute encoder
- High resolution in swivel and turning axis
- High stiffness
- Low net weight

Servomotors
By default, the servomotor type AM8012 is used. However, servomotors from other manufacturers can also be used, provided they have the following dimensions on the output drive:
- Flange: 40 x 40 mm
- Shaft diameter: 8 mm
- Bolt circle: 46 mm
- Centering: 30 mm
