Sigma-7 is a complete family of servo motors and SERVOPACK
amplifiers from 3w to 55kW, easily paired with a Yaskawa machine controller to
create a motion automation system with the industry’s highest quality and
reliability.
The SGM7A (50W - 7kW, Low Inertia) is available in a wide range of
sizes and covers the capacity spectrum from low to medium power, and the general-purpose workhorse of the Sigma-7 line. Each of these brushless
rotary servo motors is capable of producing a high rate of power at extremely
low levels of inertia. SGM7A servos are also designed to deliver high torque
performance when an application requires it. 24-bit encoder resolution
maintains industry-leading positional accuracy across the power spectrum.
The SGM7J (50W - 1.5kW, Medium Inertia) was
designed to maximize responsiveness in applications where precise load matching
is of critical importance. This family of medium inertia rotary servo motors
was created with low capacity applications in mind, yet can respond with rated
speeds to 3000 rpm and torque ratings up to 2.39 N-m (21 in-lb) when an
application requires it. 24-bit encoder resolution maintains industry-leading
positional accuracy in any operating condition.
The SGM7G (300W - 15kW, Medium Inertia) The increased power demands of large automation components utilize the robust performance of SGM7G. These servo motors are built with a compact footprint, yet provide a higher torque while maintaining an inertia rating well within the medium range. Rated torques in the SGM7G family range up to 95.2 N-m (840 in-lb). SGM7G delivers a rated speed of 1500 rpm, delivering a rapid and consistent throughput over a wide power range. 24-bit encoder resolution maintains industry-leading positional accuracy across the power spectrum.
