Product Description:

The EP3624-1434-7-56BC-CU is a permanent-magnet DC motor built by Pacific Scientific for its Permanent Magnet DC Motors series. In automated equipment, it converts electrical energy into controlled rotary motion for conveyors, winders, and positioning tables that need constant speed under load. It is supplied as a totally enclosed, non-ventilated unit that mounts directly to gearboxes or pumps through its NEMA C face, simplifying mechanical integration in compact machine layouts. Its enclosed construction is useful where external cooling airflow is limited and exposed rotating components need added protection.

This model operates from a nominal supply of 90 V provided by an SCR drive and draws a continuous armature current of 2.6 A. At that setting, it can deliver a continuous torque of 9.0 lb-in while maintaining a rated speed of 1750 rpm. The TENV housing keeps airborne contaminants away from the windings and relies on conduction to remove heat, so cabinet airflow is not required. An armature resistance of 2.63 Ω and an inductance of 10.5 mH support stable electrical behavior during steady-state operation and SCR commutation. This electrical balance helps the motor respond smoothly to commanded speed changes without abrupt current rise, and all mounting holes are arranged on the NEMA C face for alignment with standard reducers or couplings.

For short acceleration bursts, the armature can accept 52.0 A, a peak value that works with its torque constant of 4.07 lb-in/A to overcome inertia during starts and speed changes. Output power reaches 1/4 hp, placing the unit in small-machine applications where compact size matters, and the frame follows the NEMA 56C outline with an overall length of 10.38 in. The steel frame and permanent-magnet set weigh 23 lb, providing enough thermal mass to moderate temperature rise during cycling duty. This combination suits auxiliary axes and light process equipment where intermittent acceleration and compact packaging are both important.
