The Sigma-7 line of AC brushless rotary servo motors covers a full range of load requirements 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.
50W-7kW, Low Inertia
The general-purpose workhorse of the Sigma-7 line, SGM7A is available in a wide range of sizes and covers the capacity spectrum from low to medium power. 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.
