Unimotor HD

Pulse duty servo motor
0.72Nm to 85Nm (255Nm peak)
055 to 190 FramesUnimotor hd is a high dynamic brushless AC servo motor range with frames from 55mm to 190mm.

Unimotor HD is a high peak torque, low inertia motor range. The motor is designed for high dynamic applications requiring hard accelerations and decelerations including:

  • Flying shear
  • Pick and place
  • Cut-to-length
  • Industrial robotics

Unimotor HD  motors are a perfect match to Unidrive M and Digitax ST servo drives.

Compact but powerful 

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 to inertia ratio

Unimotor HD delivers very low inertia at the rotor with up to 300% peak overload for maximum dynamic performance.

Segmented Stator Design

For increased compactness and high dynamics

Larger Shafts

For increased torsional rigidity
