Product Description
ZRT Direct Drive Rotary Table: High Performance, Low Maintenance Solution.
The ZRT direct drive rotary table offers a top-notch, maintenance-free servo solution. This torque motor rotary table comes in two different structures: inner rotor and outer rotor, catering to a wide range of application needs. With diameters ranging from 60mm to 500mm and continuous torque from 10N.m to 6000N.m, there are over a dozen sizes available to choose from. The absolute accuracy of the ZRT can reach up to ± 6arc-sec, with repeated positioning accuracy up to ± 1arc-sec. It boasts high precision, high rigidity, low axial radial runout, and other outstanding features.
The ZRT achieves exceptional torque density thanks to its long diameter, short length, and numerous magnetic poles. This DDR table motor can serve as a versatile divider, offering programmable fast dividers that surpass the capabilities of traditional mechanical or variable reluctance technology dividers. It can also replace mechanical transmission components like gearboxes, synchronous belts, and rack and gear reducers. Primarily used in automation equipment and CNC machines, the ZRT functions as a crucial indexing component.
