Product Description:

The R88SENA-T2-SS-NV-03 is a servo motor manufactured by Pacific Scientific for the R Servomotors series. In industrial automation, it acts as the prime mover on coordinated axes, translating drive current into controlled rotation for conveyors, pick-and-place heads, and precision tables. Its electromechanical design supports repeatable positioning accuracy and stable velocity under variable load. That operating profile suits machines that need consistent motion response during frequent starts, stops, and direction changes.

The motor supplies a continuous stall torque of 42.2 Nm, allowing it to hold or drive loads without excessive heating, while a peak capability of 86.1 Nm covers rapid starts and short overloads. Rotor inertia is 8.61 kg·m² × 10⁻³, a moderate value that supports fast acceleration while helping smooth speed changes. A 7.5-inch square frame matches the bolt pattern of common 190 mm gearheads, easing mechanical integration. Magnetic flux is provided by samarium cobalt rare-earth material, which maintains coercivity at high winding temperatures and supports high torque density. Mechanical attachment follows the English mounting standard, so existing inch-based fixtures can often be used without modifying the machine face.

An active lamination stack length of 8 inches increases the electromagnetic path and helps the motor achieve its rated torque without enlarging the frame width. The motor uses a standard housing style that provides thermal conduction and structural rigidity for gantry or standalone mounts. Because it has no shaft seal, the output end should be protected from coolant splash or airborne particulates. The motor is shipped without a holding brake, so static loads must be secured by the drive amplifier or an external clamp during power-off states. This arrangement is best suited to enclosed machine areas where external holding and shaft-end protection are already provided.
