What motor for rehabilitation robot(dc motor robot)?
Rehabilitation robot(dc motor robot) use Rehabilitation robotics it belongs to a branch of medical robot, due to the popularity of 5G is widely used in medical, rehabilitation and other fields; rehabilitation robot(dc motor robot) in the joints, drive, tray, walking and other components widely used micro brush DC motor, motor DC tanpa berus, motor stepper, hollow cup motor, servo and other micro motors, as the drive motor.

Six, custom non-standard servo
Product name: Robot servo
Project description In order to meet the needs of various types of robot joints developed by modern high technology, we produce robot joint gearboxes with specifications ranging from 3.4MM to 45MM; in order to solve the design and manufacturing precision of the servo gear and the control of the return difference of the servo, we have optimized the design and manufacturing precision of the servo gear according to our many years of R&D and design experience combined with the market demand of robot joints to reduce the return Difference.
Different parts in the rehabilitation robot, using different micro drive motors, servo, non-standard custom drive motors, usually applied in the joint servo, drive rotation, limb interaction and other drive modules.
