Product Description:

The R46GENA-TS-RC-NV-00 servo motor is produced by Pacific Scientific within the R Servomotors series. This electromechanical unit converts regulated drive current into controllable torque, allowing coordinated positioning and speed control on conveyors, pick-and-place heads, or indexing tables used throughout industrial automation cells. It is intended for motion systems that require repeatable rotary response and stable closed-loop operation across changing load conditions. The motor is also suitable for applications that require precise starts, stops, and speed changes during repetitive cycles.

Its continuous stall capability is 7.6 Nm, so the motor can supply that torque indefinitely at zero speed without exceeding thermal limits. The motor has a 4.25" Square frame that fits standard NEMA-style mounting plates, and the rotor inertia of 0.40 kg·m²×10⁻³ supports responsive acceleration with low-mass loads. Permanent magnets made from rare earth (samarium cobalt) increase air-gap flux density so dynamic response remains linear across the speed range. During short load spikes, the motor can deliver up to 20.2 Nm. Position and velocity are measured by a Tachsyn resolver mounted on the rear housing, which supplies combined tachometer and synchro signals to legacy amplifiers. The housing is supplied in the standard style, and the motor uses a standard winding package.

The motor uses an English mounting flange, allowing inch-based bolt patterns to remain unchanged on existing machinery. Because it is built with no brake, static holding force must be supplied by the servo drive or an external mechanical latch. The shaft operates without a seal, so it is better suited to clean installations where contamination is limited. The magnetic stack measures 6 inches in length, which helps support continuous-duty torque without adding unnecessary overall length.
