Product Description:

The R46GSNA-TS-NS-NV-09 is a servo motor manufactured by Pacific Scientific as part of the R Servomotors series. In automated equipment, it converts commanded current into regulated mechanical torque so positioning tables, robotic axes, and conveyor sections can follow programmed motion profiles with repeatable response. The motor is intended for closed-loop drive systems where quick reversals, controlled acceleration, and stable holding at low speed are important to normal operation. Its general configuration suits machinery that needs dependable motion control without requiring a large motor footprint.

The unit provides a continuous stall torque of 7.6 Nm, allowing it to support static loads without excessive thermal rise during normal duty. Momentary demand can increase to 20.2 Nm for acceleration and short-duration load changes. Rotor inertia is 0.40×10⁻³ kg·m², which balances responsive speed changes with stable running behavior. Installation space is set by the 4.25-inch square frame, a common size for mid-range servo applications. Torque production uses rare-earth samarium cobalt magnets, which maintain strong magnetic flux over a broad operating temperature range. The motor is built with a standard winding and a standard housing style for use in typical servo-axis layouts.

A Tachsyn resolver supplies primary feedback so the drive can close both velocity and position loops without an external encoder. For applications that rely on drive torque or a separate mechanical lock to hold position, the motor is supplied with no brake. Axial length is 6 inches, which helps the motor fit machines where mounting depth is limited. The output end has no shaft seal, so the coupling area should be kept away from direct fluid exposure. This layout supports dry, enclosed installations where the motor can deliver feedback and torque without added brake hardware or sealed shaft features.
