Product Description:

The STF5372-3750-61-82BC is a permanent-magnet DC motor produced by Pacific Scientific within the Permanent Magnet DC Motors series. It serves as a constant-speed drive element in automated conveyors, printing lines, and material feeders where compact torque delivery is needed. By converting a fixed DC supply into rotary motion, the motor simplifies drive trains that do not require vector feedback or complex inverter control. This makes it practical for machines that rely on straightforward speed regulation rather than encoder-based positioning.

At a base speed of 1750 RPM, the shaft reaches its rated velocity when the armature receives the nominal field and armature voltage. Continuous output is capped at 72 lb-in of torque while drawing 9.3 A. These limits set the thermal steady-state range for continuous duty. The design produces torque per ampere of 7.9 lb-in/A, which supports predictable load response as current rises. Armature resistance of 0.77 Ω and inductance of 6.8 mH influence current rise time, so the drive can use smoother acceleration ramps. With a rated armature voltage of 180 V, the motor develops 2 HP through its NEMA C-face coupling, and the totally enclosed non-ventilated housing removes the need for external cooling.

For integration, the motor carries an ingress protection rating of IP65, which helps keep dust and low-pressure water jets away from the enclosure. Its overall length of 18.3 in matches the 145TC/182 frame, so it fits standard gearboxes and pump heads used on production equipment. Peak armature current reaches 93 A during startup or short overload events, while the resistance and inductance help limit rapid heating in the armature winding. Installed mass is 84 lb, which adds steadiness to belt or chain-driven systems without making the motor unusually bulky for its power class.
