SR3640-773-48C Image 1


The SR3640-773-48C is a Permanent Magnet Direct Current (PMDC) motor in the PMDC Motors by Pacific Scientific. Characterized by its high-speed capabilities, this model is ideal for high-demand operational conditions usually found in industrial settings. Furthermore, it has been crafted to endure highly intensive environments thanks to its robust design. The motor runs on 90V DC, with horsepower of 1/3 and a current of 3.1A. This results in a performance that is both effective and dependable, using only low voltage to operate optimally. The model's design also includes a range of features beneficial to its performance, such as NEMA mounting with a removable base, allowing for adequate ventilation to maintain cooling. This design supports its natural convection cooling mode, ensuring sustainable operation over time. Additionally, the SR3640-773-48C is certified to meet CSA standards such as Class 421101 and recognized by UL, making it suitable for global use. The cost-effectiveness of this model is one of its primary advantages. This is largely due to its low voltage usage, which eliminates field copper losses whilst occupying minimal space. The inclusion of patented anti-clogging magnets streamline low-speed operations, complemented by high overcurrent capacity and dynamic braking without demagnetization. Additional features that contribute to its superior performance include a Totally Enclosed Non-Ventilated (TENV) enclosure, large standard sealed bearings, and Class H insulation. Moreover, the armature of the SR3640-773-48C is impregnated with polyester, ensuring both electrical and mechanical integrity and longevity. Its constant force brush springs equipped with replaceable brushes also contribute to the motor's extended lifespan.

SR3640-773-48C by Pacific Scientific is a motor in the PMDC Series. The SR3640-773-48C features a Voltage (DC) of 90 and a Current (Amps) of 3.1. This Permanent Magnet DC Motor also has a RPM of Factory Assigned, a Factory Assigned Enclosure and a H.P. of 1/3.
