Product Description:

Pacific Scientific's R33SSNC-NS-NV-02 Servo motor is designed for use in industrial automation applications requiring excellent performance. The servo motor's design guarantees precise control and flexibility with several primary and secondary feedback possibilities. Wafer spinners in semiconductor manufacturing can rely on it because it is compatible with MS-type connectors that allow for easier integration into existing systems.

The R33SSNC-NS-NV-02 servo motor offers steady motion control with a rotor inertia of 0.063 lb-in-sec. The static friction rating of 0.8 lb-in (0.09 Nm) allows the motor to produce consistent torque. The winding resistance of 0.9 Ohms (line-to-line) contributes to an effective electrical performance. The servo motor has a continuous current capability of 6.5 When it comes to complex industrial automation, the servo motor is the greatest option for dependability and accuracy. A peak and a maximum torque output of 13 A peak. An additional 0.87 inch (22 mm) of motor length is available for use with an optional holding brake, offering increased operating control. The mounting pattern that consists of four holes with a diameter of 0.218 in (5.5 mm) equally spaced on a 3.75 in (95.3 mm) bolt circle, ensures secure installation across a wide range of equipment configurations.

The R33SSNC-NS-NV-02 motor is designed to work effectively even in demanding settings, with a peak current at torque of 13 A and a constant current capability of 6.5 A. The extra brake, that adds 0.87 inches to the motor's length, not only improves control but also expands your options for applications that require greater holding force. The servo motor's durable design and high technical standards provide reliability in complex automation systems. Consistent efficiency is obtained by the optimization of performance characteristics.
