Product Description:
The STF5356-3749-61-45BC permanent-magnet DC motor is manufactured by Pacific Scientific and belongs to the Permanent Magnet DC Motors series. It is intended for industrial automation tasks that need a steady source of rotary power, such as conveyor sections, compact geartrains, or indexing fixtures. A totally enclosed non-ventilated housing paired with an IP65 ingress protection rating lets the unit operate where airborne particles or washdown spray would damage an open machine, while its stamped-steel welded base allows rigid mounting on a 145TC frame.
The motor is designed for a supply of 180 VDC; at that voltage it draws a continuous armature current of 7.1 A. That current produces a continuous shaft torque of 54.0 lb-in, which translates to a rated mechanical output of 1.5 HP when the armature reaches its base speed of 1750 RPM. Together, these figures describe the steady-state operating range for systems that demand constant speed under load. An 11.30 in² cross-section and a 16.30 in overall length help the motor fit inside standard motor compartments without external cooling hardware, and the TENV enclosure eliminates airflow that could carry conductive dust onto live windings.
For intermittent overloads, the armature can withstand a surge of 70.0 A, giving extra acceleration margin beyond the continuous rating. A torque constant of 7.90 lb-in/A links the demanded current to produced torque, while the armature resistance of 1.11 Ω governs copper losses and temperature rise during long duty cycles. The armature inductance of 11.20 mH smooths current transitions, allowing the drive to issue rapid command changes without excessive ripple. With a mass of 65 lb, the motor provides mechanical damping for belt tension or gearbox backlash, and its stamped-steel base keeps alignment rigid during transient events.
