Matching servo amplifiers to brushless DC motors
A servo system consists of a number of elements (see diagram). One aspect of the system integration process involves matching the servo amplifier to the brushless dc motor. This may seem as simple as selecting the amplifier and motor from the same manufacturer.
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...
Motor starters stress safe, fast installation
Chicago—TeSys D Line ("Telemecanique System"), a new generation of motor starters from Schneider Electric/Square D, was introduced at the NMW show. The new D Line features smaller dc contactors for lower control power (uses less panel space and 75% less power than traditional coils), a mounting/wiring system that cuts panel connection time by 50% without tools, and finger-safe connection...
