Unimotor fm is a high performance brushless AC servo motor range with frames from 075 mm to 250 mm, matched for use with Control Techniques servo drives. The ‘fm’ stands for Flexible Motor and is designed to accommodate a wide range of applications. The motors are available in seven frame sizes with various mounting arrangements and motor lengths.

Unimotor fm provides high-precision over an extended duration requiring lower acceleration and deceleration rates. The motor is optimized for high stability in precision profiling applications including:

  • Printing
  • Winding
  • Labeling

Wide torque range

Unimotor fm offers the widest torque range, from 1.4 Nm – 136 Nm

Maximum flexibility

Flexibility of the Unimotor range ensures the best fit for your application, options include:

  • Various feedback devices to be used. As standard an incremental encoder is fitted as this offers an optimum balance of cost and performance. SinCos, EnDAT and Hiperface can be selected for increased resolution and Resolver feedback is available for increased reliability in extreme environments.
  • High inertia versions are available to allow the motor inertia to be more closely matched to the load inertia for increased performance and stability.
  • Motor brakes may be integrated within the motor.
  • Type of connectors fitted.
  • Various voltage and speed ranges are available.
