Product Description:
The R45GMBA-R2-NS-NV-00 servo motor is manufactured by Pacific Scientific for the R Servomotors series. In automated lines, it functions as the electromechanical actuator that translates drive commands into tightly controlled shaft torque and speed, supporting packaging, material-handling, and light machining operations. Its compact envelope allows straightforward machine-frame integration in installations that require reliable dynamic performance.
The motor delivers 5.7 Nm of continuous stall torque, providing holding force without overheating. For rapid indexing, it can supply up to 15.1 Nm for short intervals. Rotor inertia is 0.31 × 10⁻³ kg·m², a low value that shortens acceleration time while maintaining positional stability. The square flange measures 4.25 inches on each side, allowing the unit to fit compatible bolt patterns. High output density comes from rare-earth samarium cobalt magnets that generate strong magnetic flux. Position feedback is provided by a size-21 frameless transmitter-type resolver, and no secondary feedback device is fitted. The winding and exterior housing use the manufacturer’s standard configurations, providing consistent physical and electrical characteristics across the product line.
The motor is equipped with a 100 V DC brake that clamps the shaft when power is removed, preventing back-driving on vertical or suspended axes. The flange and pilot follow the metric mounting standard, so the unit can bolt directly to compatible European gearboxes without adapters. Because the motor has no shaft seal, the front bearing cavity must be shielded from coolant spray and abrasive dust. The active magnetic stack extends 5 inches along the stator core, balancing torque density with thermal dissipation during prolonged duty cycles. Proper clearance around the housing supports heat transfer and helps prevent excessive operating temperatures. Cables should be routed away from moving components, sharp edges, and areas where coolant or debris could damage their insulation.
