Low-Inertia Motors Move Forward Biomedical Imaging Technology
Rapid 1-mm x-y movements are accurate
to within 1 µm
Traditional instruments for positioning slides, test tubes, and microarrays have depended on leadscrew mechanisms. However, such devices are subject to friction and rotational inertia, which makes it difficult to meet OEM demands for high throughput. Low-inertia, direct-drive Micro Linear motors are a better alternative for precise, repetitive, short-distance positioning applications, according to
Copley Controls (Canton, MA). The company’s motors currently are used in blood cell– imaging devices...
