Product Description:

The R43GENA-TS-NG-NV-00 is a servo motor built by Pacific Scientific for the R Servomotors series. It converts drive current into controlled torque and speed for factory automation axes such as packaging, handling, or indexing stations. This model is intended for use with matched amplifiers and feedback loops where precise rotary positioning is required.

The motor develops a continuous stall torque of 3.9 Nm, allowing it to hold load at zero speed without overheating. Its square frame measures 4.25 inches, which sets the flange fit and installation envelope. Rotor inertia is 0.22 × 10⁻³ kg·m², helping the axis respond quickly during acceleration and deceleration. Magnetic flux is produced by samarium cobalt rare-earth magnets, which improve torque density and temperature capability. Rated output speed is 1500 rpm, making the motor suitable for mid-range motion tasks that pair with common gearbox ratios. The motor uses a standard winding, an English mounting pattern, and a standard housing. Primary feedback comes from a Tachsyn resolver that returns analog velocity and position signals. The motor is supplied without a holding brake.

Short-duration demands are covered by a peak torque limit of 10.4 Nm, which supports quick index moves without exceeding thermal limits. Position accuracy at lower speeds is refined by a secondary feedback system, an incremental encoder rated at 1024 ppr with a line-driver interface. The output shaft is provided with no shaft seal, so the motor is best installed in relatively clean areas or used with an external seal when fluids are present. A laminated core length of 3 inch balances motor weight with magnetic loading. This combination of resolver and encoder feedback supports both velocity information and finer position tracking during motion control.
