Product Description:

The R43GEBA-TS-NS-NV-00 is a Pacific Scientific servo motor in the R Servomotors series. It serves as an electromechanical actuator in automated production lines by converting electrical input into controlled rotary motion for indexing, positioning, and coordinated axis movement. This type of motor is commonly used where a drive must regulate speed and position closely while maintaining stable response under changing loads.

The motor delivers a continuous stall torque of 3.9 Nm, allowing it to hold a stationary load without rotation when the drive applies rated current. For short acceleration demands, it can reach a peak torque of 10.4 Nm, which helps the axis overcome startup friction and momentary inertia. Its rated speed is 1500 rpm, providing a practical balance between torque output and operating speed for general motion duties. Rotor inertia is 0.22 kg·m² × 10⁻³, which supports responsive tuning on appropriately matched mechanisms. Primary feedback is provided by Tachsyn, which combines tachometer and resolver functions so the controller can monitor motor speed and rotor position through one feedback device. The motor also uses samarium-cobalt magnets, and its inch-based mounting pattern matches NEMA-style mechanical interfaces.

The housing has a 4.25-inch square frame, which suits machines that need a compact motor footprint with a relatively robust face size. An integrated 100 V DC brake holds the shaft when power is removed, which is useful for axes that must remain in place at standstill. The shaft has no shaft seal, so the installation area should remain free of coolant spray and other liquid contamination. Stack length is 3 inches, helping keep the motor short enough for space-limited assemblies. The unit uses a standard housing build and a standard winding, while secondary feedback is not included on this version. English hardware is used throughout, matching inch-based mounting and fastening practices.
