Hollow Shaft Servomotors RD50x14-HW210 W | 0.54 Nm | 3870 rpm | 48 V

Hollow-shaft 50x14 drive units featuring market-leading torque density in a compact footprint. Suitable for a broad range of industrial applications.

RD50x14-HW
  • Hollow-shaft
  • Industry-leading torque density
  • Excellent overload capability
  • Compact design
  • Multiturn absolute encoder with high resolution
  • Integration of hollow shaft safety brake
With the hollow shaft servo motors of the RD series RoboDrive presents high-performance motors based on the well-established stator-rotor kits. The RoboDrive technology provides the highest power density at maximum torque range and overload capability with a maximized hollow-shaft diameter in a compact design. The hollow shaft design allows to guide signals, media and fluids, rays, and cables through the motor. The integration of gear elements, spindle nuts or optics and serial actuators expands the field of applications.
The integrated absolute encoder enables high positioning accuracy and excellent speed stability. The variable concept offers solutions for a variety of demanding drive applications. On request alternative voltage levels, increased speeds, customized torque adaptations and integrated hollow-shaft safety brakes can be realized.
