Product Description:
The R46GENA-TS-NS-NV-00 servo motor is manufactured by Pacific Scientific as part of the R Servomotors series. It is intended for closed-loop positioning tasks in which a dedicated drive delivers current in proportion to commanded torque. Its operating role is to provide repeatable rotary motion in systems that depend on accurate speed and position control. The unit uses a standard housing style that provides mechanical protection while keeping weight moderate. When integrated into multi-axis assemblies, the motor converts electrical energy into synchronized shaft rotation for pick-and-place modules, indexing tables, and other automated stages.
Rated continuous stall torque is 7.6 Nm, allowing the motor to hold that torque indefinitely without overheating when cooled as intended. During rapid acceleration, the electromagnetic circuit can reach a peak torque of 20.2 Nm, which provides short-term margin for load surges. The rotor inertia is 0.40 × 10⁻³ kg·m², balancing quick response with stable motion and helping the servo loop limit overshoot. The motor has a 4.25-inch square frame, and its mounting interface follows an English bolt circle standard that matches common North American equipment patterns. That frame format simplifies attachment to machine plates or gearboxes that use the same pilot layout.
The magnetic circuit uses rare-earth samarium cobalt magnets, which increase torque density and resist demagnetization at elevated temperatures. The motor comes with no brake, so position holding during power-off conditions must be provided by the drive or by an external mechanical clamp. Primary velocity and position data are generated by a Tachsyn resolver, and no secondary feedback device is installed, which keeps the package compact and simplifies the feedback arrangement. The laminated stack extends 6 inches along the shaft axis to produce the stated torque. The winding and stack use common production configurations, and the design omits a shaft seal, so the installation should be kept away from liquid contaminants.
