Northern Magnetics has unveiled a 24-axis linear motor driven positioning stage that provides independent motion along each of the 24 axes. The base measures 72 inches long and contains an EPS positioning stage with non-cogging, ironless core, medium-force, brushless linear motor with 12 independent coil assemblies. Each assembly consists of a 1.5-inch stroke, bellows, encoder, special bearings, and limit switches. Mounted to each of these X-axis slides is a single Y-axis special bearing positioning stage with a non-cogging medium force brushless linear motor capable of 3.5-inch stroke, encoder, and limit switches. A total of four bearings support the payload, moving coil, and encoder head. Northern Magnetics, Product Code 4214.
