Maxon Offers Exoskeleton Joint Actuator
Fitting the absolute encoder directly at the joint rotation provides designers increased positioning accuracy.
Maxon Motor has developed an exoskeleton drive for use in robotic limbs. This complete joint actuation unit consists of a pancake brushless DC motor with inertia optimized rotor. Also included is an internal high resolution encoder, planetary gearhead with absolute encoder and a position controller with CAN and RS232 interface. Fitting absolute encoder directly at the joint rotation provides designers increased positioning accuracy. The unit delivers 54 Nm of continuous torque and 120 Nm on a 20 percent duty cycle and may be operated on supplies between 10 and 50V DC and the actuation speed is up to 22 rpm. Other key features include: compact housing, integrated controller and reduced weight and cost. The ideal choice for use in hip and knee exoskeletons.
