maxon motor introduces the exoskeleton joint actuator

The global Exoskeleton market is growing in both market share and technological developments at a rapid rate each year. maxon motor have several global customers we have worked with to develop brushless DC motor solutions for use in robotic limbs.

maxon motor has developed an exoskeleton drive for use in robotic limbs. This complete joint actuation unit consists of a flat brushless DC motor (EC 890 flat) with inertia optimised rotor.

Also included with the exoskeleton drive is an internal high resolution 4096 MILE encoder, planetary gearhead with absolute encoder and a position controller (EPOS 4) with CAN and RS232 interface.

Fitting the 17 bit SSI absolute encoder directly at the joint rotation, will negate the effect of gearhead backlash, providing designers increased positioning accuracy. The unit delivers 54Nm of continuous torque and 120Nm on a 20% duty cycle. The system can be operated on supplies between 10 and 50V DC and the actuation speed is up to 22rpm.

Other key features include:

  • Compact housing
  • integrated controller
  • Reduced weight and cost

The ideal choice for use in Hip and Knee Exoskeletons.
