Product Description:
The SR3624-8291-50 is a permanent-magnet DC motor manufactured by Pacific Scientific and assigned to the Permanent Magnet DC Motors series. It delivers continuous rotary power for conveyors, feeders, and compact actuators that run directly from a low-voltage DC bus. The motor couples to industry-standard gear reducers through its NEMA C face, giving machine builders a straightforward way to add speed-controlled torque inside enclosures where airflow and space are limited.
The electrical section is rated for 90 VDC; this supply voltage establishes the insulation and commutation requirements while simplifying speed control through basic thyristor or PWM drives. At this input, the shaft turns at a base speed of 1750 rpm, a common set point that matches many pump and fan curves without extra gearing. Continuous load capability is 9.0 lb-in of torque, produced while the armature draws 2.7 A. That current-to-torque relationship is represented by a torque constant of 3.9 lb-in/A, enabling predictable closed-loop control because every additional ampere adds a fixed increment of mechanical twisting force. A 1/4-horsepower output, 56C frame size, and a 9.13-inch overall length keep the package compact. The removable base permits either foot or face mounting without altering alignment.
Dynamic events such as startup or rapid load changes are handled by a peak armature draw of 54.0 A; the drive electronics must supply this brief surge to reach the commanded speed quickly. The copper circuit presents an armature resistance of 2.5 Ω and an inductance of 9.6 mH. These electrical values affect current ripple and determine the required size of filtering components in the controller. A totally enclosed, nonventilated housing classified as TENV prevents ambient dust from reaching the windings. The 18-pound weight provides enough thermal mass to keep temperatures within rated limits during steady operation.
