Joint motors are specialized in the design, development, and production of robotic joints. The motor has a combination of hollow and large apertures, which can ensure the perfect fusion of joint modules. The stator and rotor mechanism of the motor is compact. The rotor uses high-performance rare earth permanent magnet materials. And the rotational inertia is small, and the dynamic response is fast. The main applications include automated production lines, robotic joints, robotic joints, medical and medical instruments and equipment, precision instruments and industrial control systems, and many other applications.
Ultra-low torque pulsation, easy speed control and precise positioning, compact structure, lightweight, low inertia
● Large hollow frameless motor, the outer diameter of the stator is only 54mm
● The fixed rotor has a compact structure with a total weight of only 0.27kg. The rotor uses high-performance rare earth permanent magnet materials.
● Superheat dissipation and low noise
● High accuracy, precise positioning, strong output, the continuous output torque of 0.42Nm
● Small moment of inertia and fast dynamic response
● Minimal torque ripple, low moment of inertia, fast dynamic response
● Powerful and smooth at low speed, stable and reliable at high speed, the maximum speed can reach 4000RPM
● Configure Hall sensor
