Tubular linear servo motor packs punch

Chicago —Shown at NMW, Series 4000 and 5000 direct-drive linear servo motors offer high force per volume in a tubular configuration. Ring-shaped neodymium magnets of alternating polarity line the length of the output shaft, which is the motor's only moving part. The cylindrical stator—also composed of rings (with teeth and slots)—fits around the shaft, producing smooth electr...
