Bionics Prosthetics and Exoskeletons



Bionic and Exoskeleton systems are used to help mobility-impaired persons to regain their mobility and independence, as well as to enhance human body capabilities in a factory or other challenging environments. Mini motors play a key role in these systems, powering rotation at the joint to drive movement of the limbs. Portescap's miniature motors are well-suited for both upper limb systems, including the shoulder, elbow wrist, hand, and lower limb systems, such as hips, knees, ankles, and feet.

Portescap's brush DC coreless and brushless slotless Ultra ECTM motors are a perfect fit for these applications, given their power density for easier and more compact integration into the bionic and exoskeleton systems; low weight and high precision for superior handling; and high efficiency for increased battery life. These motors also provide excellent heat dissipation and high torque at low speed. Combining motor accessories such as planetary gearheads to adapt the motor speed and torque, or encoders for precise position control and smooth motion, allows the miniaturized motion system to maximize its power density while retaining its compact footprint.
