Flat Motors Gain Integrated Speed Controller

June 25, 2020

The BXT motor family, consisting of brushless DC-servomotors with especially short design, was expanded in all sizes with a diameter-compliant, integrated Speed Controller. With an additional attachment length of just 6.2 mm, the Motor/Speed Controller combinations are available with the same installation space as the products with the IEF3-4096 (L) integrated encoder. Through the use of synergy effects with the encoder variants, the Speed Controller is likewise fully integrated into the robust motor housing.


Based on the FAULHABER SC technology, the motors can be put into operation quickly, easily, and comfortably with the Motion Manager. The Speed Controller is connected to the application with a six-pole flat cable, suitable connectors are available as an option.


The Speed Controller can be combined with 2214, 3216 BXT H, and 422 BXT H housed BXT motors. Even with full integration, the Speed Controller guarantees the use of nearly the entire power and speed range of the corresponding base motors. A well-designed cooling concept minimizes thermal losses here.


The combination of the BXT H motors with the integrated Speed Controller is the ideal solution if speeds need to be controlled precisely in the smallest of spaces and high torques are also required. Typical applications are pumps, equipment manufacturing, laboratory, and industrial automation.

  • Compact design through complete integration
  • High torque up to 92 mNm, continuous output up to 60W
  • Stable and precise mechanical speed control from 200 to 10,000 min-1
  • Second shaft end optionally available in sizes 32 and 42 mm
