Product Description:

The R43GENA-TS-M2-VS-02 is a servo motor manufactured by Pacific Scientific as part of the R Servomotors series. It is intended for industrial automation tasks where precise rotary motion is required in indexing tables, material-handling modules, and process equipment. By converting commanded electrical power into controlled shaft torque and speed, the unit provides tightly regulated motion profiles that can be integrated into closed-loop control systems. It is well suited to applications that require repeatable starts, stops, and speed changes under drive control.

It has a continuous stall capability of 3.9 Nm, allowing the axis to hold load torque steadily during dwell periods. The square frame measures 4.25" on each side, so it fits English-dimension mounting plates while preserving thermal surface area. Rotor inertia is 0.22 kg·m² × 10⁻³, and this modest value lets the drive command rapid acceleration without excessive current demand. For short transients, the motor can deliver a peak torque of 10.4 Nm, providing overload margin for start-up or sudden load changes. At a rated speed of 1500 rpm, the electromagnetic design balances torque production with manageable back EMF. The English mounting interface eases alignment, and the standard housing supports straightforward enclosure integration. Because the unit is supplied without a holding brake, external means must be used when power-off position retention is required.

Motion feedback is supplied by a Tachsyn device that returns both velocity and position information to the drive. Torque density is enhanced by rare-earth magnets that use samarium cobalt, which helps maintain magnetic strength over a wide temperature range. A Viton shaft seal protects the internal bearings from fluid ingress. The active stack is only 3 inches long, which helps keep the overall motor length compact. This shorter stack can be useful in machine sections where couplings, guards, or nearby components limit axial space.
