SR3642-4982-7-10-56BC
The SR3642-4982-7-10-56BC from Pacific Scientific is a robust member of the Permanent Magnet DC Motors series, engineered for continuous-duty applications. This 180 VDC motor delivers a current of 26 Amps and is rated at 1/2 HP, achieving a nominal speed of 1750 RPM. It is built to NEMA standards within a 56C frame size and housed in a TENV non-vented enclosure with a removable base and NEMA C face. The gasketed conduit box provides a generous wiring compartment for quick termination and secure connections. The design incorporates a removable conduit cover and field-replaceable brushes, ensuring maintenance simplicity and minimal downtime.
Performance is optimized through a continuous torque of 18 lb-in and a torque constant of 7.6 lb-in/A, delivering smooth load response and precise speed control. The armature winding exhibits a resistance of 3.3 Ω and an inductance of 16.2 mH, producing stable current regulation and low electrical noise. With high overcurrent capacity and built-in dynamic braking capability that resists demagnetization, this motor absorbs transient loads effectively. The polyester-impregnated armature ensures mechanical and electrical integrity under rapid load changes, while the brush springs maintain constant contact force for extended brush life. Large sealed bearings further reduce friction and support radial and axial loads in demanding duty cycles.
Reliability is enhanced by Class H insulation, enabling operation in elevated temperature environments without performance degradation. The unit holds multiple approvals—UL Recognized, CE Marked, and CSA Certified—for global deployment in industrial and medical settings. Compact at 12.13 inches in length and weighing 27 pounds, it integrates easily into existing drive systems and machinery. Applications range from surgical robots and laser heart surgery equipment to precision automation in high-performance manufacturing. Backed by a one-year warranty, the SR3642-4982-7-10-56BC provides a dependable solution where durability, maintainability, and precise torque delivery are paramount.
