Product Overview
1. Product Overview
The hollow rotary platform, driven by a motor, achieves automated angle adjustment. It is a revolutionary product in rotary motion mechanisms, capable of replacing both DD motors and dividers, striking a balance between the two. With a repeatability of ≤5 seconds, the motor is easily configured, provides stable load-bearing capacity, and can be paired with AC servo motors or stepper motors for arbitrary angle division. It can satisfy digital control requirements that dividers cannot achieve, and its positioning accuracy rivals that of DD motors. This significantly reduces costs and brings unexpected results.
2、Product Features
◆High output, high rigidity, high precision, high efficiency, high-hardness tooth surface, and low noise;
◆The rotating surface can directly lock the workpiece, improving the ease of workpiece loading;
◆High precision, positioning accuracy less than 1 arcmin, repeatability up to ±5 arcsec;
◆Smooth and stable rotation of the disc, and rapid positioning; compatible with servo and stepper motors from various manufacturers;
◆Hollow structure design, convenient for wiring and piping, and allows for arbitrary motor configuration.
