High dynamic AC brushless servo motor

Unimotor hd is a high dynamic brushless AC servo motor range designed for use in pulse duty applications where rapid acceleration and deceleration are required. The motors are available in frame sizes from 060 to 190.

The perfect mix of application-specific features developed into a single solution

For torque control applications

Unimotor hd is designed using a proven development process that prioritises innovation and reliability. This process has resulted in a market leading reputation for both performance
and quality.

Matched motor and drive combinations

Drives and motors from Control Techniques are designed to function as an optimized system. Unimotor hd is the perfect partner for Digitax and Unidrive.

Accuracy and resolution to suit your application requirements

Choosing the right feedback device for your application is critical in getting optimum performance. Unimotor hd has a range of feedback options that offer different levels of accuracy and resolution to suit most applications:

  • Loaded with parameter management features, including cloning
  • Easy-to-read dynamic logic diagrams so you can visualise and manage the drive in real time
  • Resolver: robust for extreme applications and conditions (low accuracy, medium resolution)
  • Incremental encoder: for cost-sensitive applications (low accuracy, medium resolution)
  • Inductive, & SinCos/Absolute: medium accuracy, high resolution
  • Optical/SinCos/Absolute: high accuracy, high resolution
  • EnDat protocol supported
  • Safety encoder option to meet SIL 3 safety category

The ultimate motor and drive combination

Control Techniques offer drive and motor combinations that provide an optimised system in terms of ratings, performance, cost and ease of use. Unimotor hd motors fitted with high resolution EnDat encoders are pre-loaded with the motor “electronic nameplate” data during the manufacturing process. This data can be read by any of our servo drives and used to automatically optimise the drive settings. This feature simplifies commissioning and maintenance, ensures consistent performance and saves time.




Compact servo motor

  • Unimotor hd provides an exceptionally compact, low inertia solution for applications where very high torque is required during rapid acceleration and deceleration profiles.

High torque

  • The Unimotor hd torque profile is matched to Digitax hd servo drives, providing up to 300% peak overload for maximum dynamic performance.
