Product Description:

The SR3616-8290-7-56C is a permanent-magnet DC motor manufactured by Pacific Scientific within the Permanent Magnet DC Motors series. It converts low-voltage direct current into controlled rotation for conveyors, compact actuators, and light-duty tooling. By supplying stable shaft speed and repeatable torque, the unit supports positioning and material-handling tasks where simple speed regulation and rapid start-stop cycles are required in automated equipment. Its compact frame lets it fit into panels and machine structures with limited clearance.

During continuous duty, the armature draws 1.5 A, which indicates the motor's thermal steady state. When supplied with 90 V DC, the unit reaches its intended operating point without external voltage boosting. At this operating point, the shaft turns at 1750 rpm, a common base speed for pulley or gearbox arrangements. Continuous torque of 4.5 lb-in is available across the normal operating range, while a torque constant of 4.0 lb-in/A lets current-based control circuits estimate output torque directly from armature current. An armature inductance of 19.4 mH helps smooth commutation switching, and the 2.9 lb-in inertia helps limit speed overshoot during load changes.

During transient events, the winding can accept a peak current of 34.0 A for short durations, providing additional acceleration torque. At rated conditions, the shaft power is 1/8 HP, which is suitable for auxiliary axes, indexing tables, or small pump drives. Copper losses are limited by an armature resistance of 5.3 Ω, which supports efficient operation during extended duty cycles. The enclosure is classified as TENV, so external airflow is not required and airborne particles are kept out of the housing. A C-face with a removable base allows either face mounting or foot mounting, and the 56C frame matches the mechanical interchangeability used by other NEMA motors in the same class.
