Product Description:
The SRF5570-4986-84-5-82BC-CU is a permanent-magnet industrial motor produced by Kollmorgen within the SR and SRF Permanent Magnet Motors series. It is intended for fixed-speed conveyor sections, mixers, and other continuous-duty axes where a direct current supply is available and precise speed regulation is not required. As a totally enclosed fan-cooled unit, it helps protect the windings from airborne debris during plant operation. The removable base allows conversion between foot and flange mounting to match available machine interfaces.
Under steady thermal conditions, the rotor can deliver 108.0 lb-in of torque while drawing a continuous current of 14.0 A. The motor is rated at 3 HP, so the connected drive must support that output level during normal operation. A base speed of 1750 RPM matches common DC drive setpoints and suits replacement of older NEMA motors in existing equipment. Its armature circuit is designed for a nominal bus of 180 V, and the combination of armature resistance and inductance helps smooth current response during operation. This operating range is well suited to machines that run for long periods at a stable speed.
A torque constant of 9.3 lb-in/A shows how much shaft torque rises with each additional ampere, which supports responsive current control. The armature inductance is 7.2 mH, and momentary overloads are handled by a peak armature current of 78.0 A before saturation or thermal limits become critical. The frame follows the 145TC/182 NEMA pattern, which helps the motor fit standard gearbox or pump interfaces without special adapters. Its 19.75-inch overall length keeps the 87-pound assembly compact for its output. That size is useful where available mounting space is limited but steady mechanical power is still required.
