Product Description:
The SR3624-4573-7-56BC permanent-magnet motor is manufactured by Kollmorgen and belongs to the SR and SRF Permanent Magnet Motors series. In industrial automation, it is selected to drive conveyors, pumps, or positioning tables where tight speed regulation and a compact footprint are required. The unit converts DC bus power from a matched drive into torque without the slip losses found in induction designs, providing higher efficiency in a familiar 56-frame package.
A rated speed of 1750 rpm indicates the regulated shaft velocity under full load, making control-loop tuning straightforward for standard operating conditions. The TENV enclosure is totally enclosed and nonventilated, so airborne contaminants cannot circulate through the windings; however, external cooling airflow may be necessary at high ambient temperatures. Frame code 56C indicates the motor diameter, foot pattern, and C-face register for compatibility with equipment designed for this NEMA frame. A shaft diameter of 0.6250 in establishes the required bore size for couplings or pulleys that carry the load. The 5.875 in bolt circle aligns the mounting holes with compatible gearboxes or pump heads. The removable base permits either foot mounting or face mounting without special adapters.
The integrated mounting face uses a NEMA C-face mounting pattern and is complemented by a housing outside diameter of 6.50 in, providing a broad mounting surface that helps minimize runout when the motor is flange-mounted. A key measuring 0.188 × 1.38 in seats in the shaft keyway to transmit torque without slipping, while the 4.500 in pilot diameter centers the motor precisely in mating equipment. Four 3/8-16 UNC-2B tapped holes in the mounting flange accept standard fasteners and provide secure attachment to the driven assembly. The face-mounted construction does not require through-bolts that protrude beyond the frame, which helps preserve clearance around the motor housing and adjacent equipment.
