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 54Nm of continuous torque and 120Nm on a 20% duty cycle and may 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 and reduced weight and cost. It is a suitable choice for use in both hip and knee exoskeletons.
