Servo Drives and Servo Motors


Control Techniques servo drives and servo motors: high performance combined with maximum flexibility

The servo drives can connect to a wide range of motion controllers through I/O or dedicated communication networks such as EtherCAT or alternatively, take control of the automation system through the drives integrated motion controller.

Unimotor is a comprehensive family of high performance AC brushless servo motors. With a wide torque range, from 0.72 Nm up to 136 Nm, rated speeds from 1000 rpm to 6000 rpm, several inertia levels and a broad selection of feedback options, Unimotor offers the perfect fit for any application requirement. Various mounting arrangements and a single cable option provide additional flexibility, while drive integration with electronic nameplate offers ultimate ease of use.

To optimize performance, we segment our servo drives and motors by the duty required for the application. 

  • Pulse Duty - High dynamic applications requiring hard accelerations and decelerations. Examples are pick-and-place, flying shear and other cut-to-length machines. These applications are characterized by high peak (e.g. 300% overload) and moderate RMS torque.
  • Continuous Duty - High-precision over an extended duration requiring lower acceleration and deceleration rates. Examples include printing, winding and labelling. These applications are characterized by moderate peak and high RMS torque.
