Yaskawa: Rotary Servo Motors (SGM7G Series)
The Sigma-7 line of AC brushless rotary servo motors covers a full range of load requirement in both small and medium capacities. The advanced technology built into Sigma-7 sets a new industry standard for responsiveness, precision and long-term reliability. Each Sigma-7 motor is engineered to maximize compatibility with existing Sigma-5 motors in control electronics, electrical rating and mounting conventions. Sigma-7 motors can be equipped with matching gearheads to suit a wider range of speed or mechanical linkage requirements.
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.
