Product Description:
The EP3648-4952-7-56BC-CU is a motor produced by Kollmorgen within the EP High Performance Motors series. Built on a NEMA 56C frame, it is intended for industrial automation tasks where a compact, low-voltage prime mover must convert electrical energy from 24-volt supplies into controlled rotary motion for pumps, small conveyors, or positioning axes. A totally enclosed non-ventilated (TENV) enclosure keeps internal components isolated from airborne contaminants during continuous duty.
The drive section must be able to supply a continuous armature current of 28.2 A; this current rating establishes the minimum output capability of the associated power stage. At that current, the shaft delivers 27.0 lb-in of torque, providing predictable load-holding capacity under steady thermal conditions. Operating from a bus of 24 V, the motor exhibits a winding resistance of 0.06 Ω, so steady-state electrical dissipation equals I²R losses that affect temperature rise. Winding inductance is 0.22 mH; this low value allows fast current changes, enabling the controller to impose rapid torque corrections with minimal delay. The 1.02 lb-in/A torque constant links commanded current to produced torque, allowing straightforward current-mode regulation. A 0.188 × 1.38 in key transmits mechanical power to couplings, and the 5.875 in mounting bolt circle aligns the housing to standard C-face gearheads or pumps.
The motor sustains a rated speed of 1750 RPM and a mechanical output of 3/4 HP during continuous duty, which gives it a steady operating range without forced ventilation. The ground shaft diameter of 0.6250 in supports common bore sizes while maintaining allowable deflection limits during coupled operation. Overall motor length is 13.38 in, which helps with clearance planning in compact machine layouts. The assembly weighs 33 lb, and the 56C face supports mounting on standard C-face equipment used in many industrial systems.
