Only 36 ms requires an ATR152 for 90 ° rotation. The new rotary table from A-Drive is one of the most dynamic of its kind. It shows its strengths in tasks with short cycle times and precise positioning. With 152 mm diameter and 136 mm height, the ATR is much more compact than comparable drives.
At the same time, according to the manufacturer, his performance data are better in all areas. The patent pending motor technology does not need an iron core. As a result, due to the lower mass and consequent lower mass inertia dynamic movements are possible with which fast production cycles are realized. The faster the movements, the greater the inertia to be overcome in motors with iron core. This requires ever higher moments, which are usually achieved over more mass. The ironless ATR152 is therefore generally better suited for fast cycle times. He reaches a speed of 822 min-1 and a permanent moment of 20,6 Nm. This can be three times higher in load peaks with 61,8 Nm, which represents a very high overload value.
Synchronization and the positioning accuracy of the drive are ensured by the preloaded four-point bearings used. A highly interpolatable Sincos encoder in single or multi-turn design ensures the required signal quality. With suitable control electronics and the necessary interfaces, the turntable is suitable for dynamic drive tasks with high accuracy requirements.
