Product Description:
The R43GENA-TS-NS-NV-00 is a brushless servo motor manufactured by Pacific Scientific within the R Servomotors series. Designed for closed-loop motion axes, the unit converts drive current into repeatable torque and speed so automated machines can index, track, or hold precise positions. Its design suits packaging, material-handling, and general automation applications where a compact square-frame motor with integrated feedback simplifies the mechanical layout and reduces the need for external transmission components.
The motor provides a continuous stall torque of 3.9 Nm, allowing the shaft to sustain a static load without exceeding thermal limits. For rapid acceleration, the motor can reach a peak torque of 10.4 Nm during short duty cycles. The square mounting face measures 4.25 inches per side, establishing the bolt circle and pilot dimensions used with inch-based mounts. The reflected rotor inertia is 0.22 kg·m² × 10⁻³, supporting high-bandwidth velocity loops because the drive moves a relatively small rotating mass. Nominal operation occurs at 1500 rpm, allowing gear ratios to be selected around a predictable base speed without overspeeding the magnetic circuit.
The magnetic field is produced by rare-earth samarium-cobalt magnets, which increase flux density without enlarging the motor frame. A laminated stack length of 3 inches provides the active iron volume needed to support the rated torque. The motor attaches to machinery through an inch-based mounting interface. Rotor position is reported by a Tachsyn transducer, eliminating the need for secondary feedback, so no auxiliary resolver or encoder is fitted. The housing follows the standard style and does not include a factory-installed holding brake. No shaft seal is provided, so external protection may be required in wet environments. A standard winding pattern balances line current and thermal rise while keeping peak and continuous performance within the stated operating limits.
