Using ironless motors, linear positioners achieve high performance at an economical cost while having the design flexibility to accommodate customisation. Parker, a leading supplier of motion control technology, has added to its family of Trilogy I-Force positioners. Built around the 110 model of Trilogy's I-Force ironless motors, the T1D and T1S include everything needed for motion except the drive and controller. These ready-to-run positioners achieve high performance at an economical cost while preserving the design flexibility to accommodate customisation. Trilogy's positioners have selectable single- or dual-square rail bearings to match the performance and cost requirements for each application. In addition, they are designed to connect together using transition plates for X, Y or multi-axis configurations.
