Gear Motor RD85x13-HD440 W | 67 Nm | 18 rpm | 48 V

Powerful, compact RD85x13 drives with Harmonic Drive gear actuators for high-precision, backlash-free applications in industry and robotics.

RD85x13-HD
  • Hollow-shaft
  • Industry-leading torque density
  • Excellent torque density and positioning accuracy
  • Multiturn absolute encoder with high resolution
  • Very compact and lightweight design
  • Integration of hollow-shaft safety brake possible
The geared motors of the RD-HD series are high-torque and high-precision servo solutions with hollow-shaft for low-voltage applications. The technology from Harmonic Drive uniquely combines highest precision and zero backlash in a compact lightweight design. RoboDrive technology allows Harmonic Drive gears to be operated at their peak performance. Due to the outstanding dynamics of the RoboDrive motors and the very low gear elasticity and inertia it is possible to precisely control the powertrain.
This allows the geared motors RD-HD to be used successfully in robotics, handling and automation, medical and optical applications. On request other sizes and types of Harmonic Drive gears are delivered with matching motors.
