DM66200H Stepper Drives

The FAULHABER DM66200H is a direct drive Stepper Motor, not only does it achieve impressive performance in terms of both speed and torque, It also operates backlash-free!
Mechanically the drive can be integrated with very limited effort since it has a relatively low weight and an extremely slim design. Thanks to minimal wear (bearing only), it is also ideal for maintenance-free continuous operation.

How it works

The DM66200H rotor runs around the opening and drives the surrounding mechanics directly without the need for a transmission. Using tried-and-tested stepper technology this drive is extremely energy-efficient and requires neither a brake nor an encoder. With a high resolution of 1.8° in full-step mode, it can execute positioning tasks precisely in open loop operation.
Torque, speed, precision
Because the moving mass of the rotor is small, speeds of up to 2000 rpm possible. A dynamic torque of up to 180 mNm can be achieved for moving large loads.

Typical Applications

DM66200H is suitable for application where cables need to be guided through the aperture or in where gases, fluids or light signals need to pass through the opening.

  • Optics (e.g., for microscope stages, apertures, zoom lenses, laser beam controls, etc)
  • Impellers
  • Prostheses
  • Robotics

As well as many different control and positioning tasks

A superior new approach for Hollow shaft solutions

Compared other hollow drive solutions the DM66200H offers the following advantages

  • An aperture larger than most conventional motor solutions (up to 40mm)
  • Ease of integration compared to Torque motors which are heavy and cannot achieve high speeds.
  • Simpler design compared to a motor + bearing system which often require complex transmission and exhibit backlash.
  • Less volume & weight compared to most hybrid steppers with reluctance technology

The DM66200H drive offers optimum speed-torque balance with minimal weight and volume.
