Product Description:

The SR3624-1032-7-56BC-CU is a permanent magnet DC motor produced by Pacific Scientific within the Permanent Magnet DC Motors series. Designed for fixed-speed or variable-speed service from a matched DC drive, the unit converts electrical power into mechanical rotation for conveyors, small pumps, and positioning stages used throughout factory automation. Its magnetic field is supplied by permanent magnets, eliminating field windings and supporting stable speed regulation under moderate load changes. Because it is a brushed DC motor, it is well suited to applications that need straightforward speed adjustment and compact packaging.

At a base speed of 1750 rpm, the armature reaches the rated mechanical output while remaining within commutation limits. The motor is intended for a supply of 180 V DC, and this operating voltage supports predictable speed control from the drive. Under continuous duty, it produces 9.0 lb-in of shaft torque while drawing 1.4 A of armature current, which helps keep thermal rise within T-class insulation margins. A torque constant of 7.4 lb-in/A links electrical input to developed torque, making the relationship between current and shaft output easy to follow. In closed-loop systems, that relationship helps the drive respond smoothly when load demand changes.

During short accelerations, the armature can accept 28.0 A, delivering several times rated torque for brief demand changes. The motor’s mechanical output is limited to 1/4 HP, matching small material-handling drives that require continuous service yet modest power. Armature resistance of 9.6 Ω influences initial inrush current and affects the slope of the speed-torque curve when operated from a linear supply. The totally enclosed, non-ventilated housing is specified as TENV; this enclosure protects the internal windings from airborne particles and supports use in lightly contaminated areas. Its enclosed body also avoids reliance on external airflow through the housing. A 56C flange, 9.13-inch overall length, an inductance of 42.8 mH, and an 18-pound mass allow the motor to fit standard NEMA adapters while maintaining smooth current transitions.
