Product Description:

The STF3720-3744-61-2 is a permanent-magnet direct-current motor produced by Pacific Scientific within its Permanent Magnet DC Motors series. This fractional-horsepower unit is intended for industrial automation tasks that need steady torque from a compact package, such as conveyor belts, indexing tables, light actuators, and packaging spindles. By coupling a fixed magnetic field with an armature regulated by a simple drive, the motor delivers predictable speed control and straightforward integration into low-voltage motion loops.

To sustain continuous operation, the armature draws 2.5 A of current, a limit that helps guard the windings against excessive thermal rise. The drive must supply a stabilized bus of 90 VDC, and varying this voltage directly adjusts shaft speed because field flux remains constant. When rated at 1/4 HP, the motor can deliver roughly 0.19 kW of mechanical output for small material-handling loads. A totally enclosed, non-ventilated enclosure, coded as TENV, seals the frame so airborne dust does not circulate through the interior, and heat is rejected through the outer housing. The mounting interface follows the NEMA C Face pattern, allowing the shaft to bolt directly to gearboxes or pumps without alignment shims.

During load regulation, the armature reaches a base speed of 1750 RPM, giving standard drive systems a familiar reference point for gear calculations. The housing is tested to IP65, so low-pressure water jets and fine particulate do not penetrate the sealing gaskets, making the motor suitable for washdown conveyor zones. A removable base for foot or face mounting is supplied, allowing the motor to be used in machines that require either mounting style. This arrangement supports compact layouts where direct face attachment or base support is needed.
