Product Description:
The STF5332-3748-61-56BC is a permanent-magnet DC motor manufactured by Pacific Scientific and supplied within the Permanent Magnet DC Motors series. A welded base allows direct foot mounting to standard machinery, while the NEMA 56C flange aligns the shaft to gearboxes or pumps without additional adapters. The totally enclosed non-ventilated housing prevents airflow through the frame, which suits dusty plant floors. At 13.30 inches overall length and 41 lb shipping weight, the unit fits compact drive bays without exceeding typical lifting limits. In automated material-handling lines, the motor provides regulated shaft power for conveyors, mixers, or positioning tables that rely on constant-speed DC drives.
Its continuous operating point uses a winding current of 4.6 A, which produces 36.0 lb-in of shaft torque while limiting thermal rise inside the lamination stack. The armature is designed for a nominal bus of 180 VDC; at that voltage the motor runs at a base speed of 1750 rpm, giving direct coupling to standard 1:1 belt transmissions. Electrical time response is shaped by an inductance of 32.00 mH and a resistance of 2.40 Ω, so current loops in the drive amplifier must accommodate the stored magnetic energy when reversing load.
For short overloads, the winding can accept a surge of 36.0 A, allowing rapid acceleration of inertial loads before duty reverts to the continuous region. Each ampere contributes approximately 8.00 lb-in/A thanks to the motor’s torque constant, which simplifies feed-forward calculations in closed-loop controllers. When run at rated speed, this electromagnetic package yields 1.0 hp at the output shaft. An IP65 rating seals the bearing and terminal areas against dust and low-pressure water jets, complementing the welded base for floor-level installation in wash-down or outdoor enclosures.
