SIKO’s new DriveLine AG04B actuator with integrated bus interface enables automation of feed and auxiliary axes. A useful option is the integration of a spring brake, which guarantees a secure hold even in a currentless state. The hollow shaft design in stainless steel, with a maximum shaft diameter of 20mm. The actuator integrates the position measuring system, entire control electronics and fieldbus interface in its aluminum housing. The brushless 24V EC motor has an output of 150W and is without wear. Depending on the gear ratio selected, an output torque of 2.5Nm to 14Nm with nominal speeds of 350 to 70 min-1 is available. The contactless absolute magnetic measuring system, with 1.024 steps per revolution and 4096 revolutions, achieves position values with a high resolution.
