Product Description:

The EP3624-5269-7-56BC-CU is a permanent-magnet DC motor produced by Kollmorgen within the EP High Performance Motors series. The unit occupies a NEMA 56C frame and drives loads through a 0.625-inch shaft, allowing direct coupling to gearboxes or pulley systems. Its totally enclosed non-ventilated enclosure keeps contaminants away from the windings, making the motor suitable for machine tools or packaging equipment that operate in confined panels where forced airflow is not available. When used with a servo amplifier, the motor delivers regulated torque and speed to support repeatable process control in automated lines.

The electrical rating is a continuous current of 1.3 A at a bus voltage of 180 V, so the drive can supply stable armature power without overheating the windings. Under these steady-state conditions, the shaft develops 9.0 lb-in of continuous torque, and the design maintains that output up to the base speed of 1750 rpm. Torque rises in direct proportion to current because the motor’s torque constant is 8.10 lb-in/A, and this linear relationship supports stable closed-loop operation. With an inductance of 51.80 mH, the armature resists rapid current change, filtering switching ripple from PWM amplifiers and improving velocity smoothness during light-load moves.

For acceleration bursts, the controller may deliver a peak current of 26.0 A, allowing the rotor to overcome its 4.0 lb-in² inertia and bring the connected load to speed in short cycles. The armature resistance of 10.50 Ω indicates the level of copper loss at a given operating point and should be included in thermal models for duty-cycle planning. At its mechanical output of 1/4 hp, the motor weighs 23 lb, measures 10.38 in overall, and mounts on a 5.875-inch bolt circle, giving machine builders a compact package that fits standard C-face gear reducers without external ventilation equipment.
