Industrial Duty Brushes Linear Motors

Yaskawa Electric America, Inc. launches the Linear Sigma Series, one of the most comprehensive lines of linear motors to enter the general motion control market in the U.S. Reflecting the company's rich history in critical linear motor applications, the newly standardized offering for the U.S. market includes coreless balanced linear motors and two types of iron core linear motors. The unique design of the iron core linear motors negates the unwanted effects of magnetic attraction between the iron core motor coil and the permanent magnet tracks.

Ranging from 140N to 6000N of linear thrusts over 24 available coil configurations, the Linear Sigma Series, coupled with the high performance Sigma lI digital servo amplifiers, provides a cost-effective plug-and-play linear motor solution for virtually every machine design of today's fast paced industrial automation fields.

Because the Linear Sigma Series was developed as an integral component of Yaskawa's Sigma II Series AC servo system, the digital servo amplifiers utilize an intelligent serial encoder feedback system to automatically recognize which model of linear or rotary servomotor is connected upon power-up, and automatically self-configure themselves. This feature enables quick and simple setup of the Linear Sigma Series drives, and increases system reliability.

The new Linear Sigma Series motors are available in two product levels. The level-I group provides a wide array of linear motors with plug-and-play Sigma II servo amplifiers. The level-II group provides a range of fully integrated linear positioning slides with linear encoders and amplifiers as an Ethernet-ready motion control system solution for the general automation industry.

Yaskawa, with headquarters in Waukegan, Illinois, is a leading manufacturer of high-performance variable speed AC drives, servos, CNCs, machine controllers, and robots. The company's technological leadership and quality performance record spans its 85-year history. Yaskawa is a recipient of ISO 9000 and holds international quality excellence awards, including the prestigious Deming Application Prize.
