We help you to develop better products in a shorter time
our compact and efficient, high-performance, decentral servo drives enable OEMs such as robot manufacturers and machine builders to realize better products in less time.
With their circular shape and hollow shaft they are ideal for fully integrated hollow-shaft actuators that are mainly used in robot arms.
Servo drive and position encoders work as one! Circulo features up to two integrated absolute encoders with no extra cables and no inconvenient encoder calibration tools.
