A traditional servo rotary actuator consists of a rotor, stator, housing, bearings, end caps, and feedback components. A frameless motor removes all redundant mechanical structures and retains only the electromagnetic conversion core. The rotor becomes a direct part of the load shaft, while the stator is integrated into the machine structure through bonding, locking, or potting.

This article introduces seven manufacturers of harmonic drive reducers, primarily companies from China and Japan.

Harmonic drive gear systems and harmonic drive actuator systems are highly suitable for applications such as turret rotation, missile fin control, and stabilized sensor gimbal systems. This is mainly because they offer unique advantages in precision, compact size, fast response, and reliability, making them ideal for high-precision electromechanical systems.

In the daily use of robot joint modules, the stable preservation of parameters is the key factor to ensure the continuous and efficient operation of the equipment. For robot joint modules, mastering the correct parameter power-off saving method can effectively avoid data loss caused by accidental power failure.
