Product Description:
The R43GENA-R2-M2-NV-02 is an AC brushless unit in the R Servomotors series produced by Pacific Scientific. Classified as a servo motor, it interfaces with a matched drive to deliver commanded torque and speed for precision axes such as index tables, gantry joints, and feed rollers in automated cells. Closed-loop operation enables tight following of motion profiles while minimizing overshoot and shortening settling time. Its brushless design also supports stable commutation during frequent starts, stops, and reversing cycles.
The device produces a continuous stall torque of 3.9 Nm, maintaining load support without overheating under steady current. During rapid acceleration, it can reach a peak of 10.4 Nm, giving extra margin for short duty cycles. A rotor inertia of 0.22 ×10-3 kg·m² yields quick response while still providing useful resistance to sudden speed changes. The windings are rated for a base mechanical velocity of 1500 rpm, so a standard industrial drive can supply sinusoidal current without field weakening. With a 4.25" square frame, the motor fits common mounting footprints, and English-thread hardware aligns with this pattern. The housing style and winding are standard, which keeps the configuration straightforward for general industrial motion duties.
A stack length of 3 inches sets the axial package and the active copper volume available for the stated torque output. Magnetic excitation is provided by a rare earth samarium cobalt rotor set, which maintains flux at elevated temperatures. The model has no brake, so positional holding relies on drive current or an external lock. Position feedback comes from a frameless resolver in size 21 transmitter format, delivering noise-resistant analog signals to the controller. Resolver-based feedback is also useful in installations where electrical interference from nearby power devices can affect more delicate signal types. Because there is no shaft seal, installation should avoid fluid exposure, and dry mounting locations are preferred.
