Product Description:
The EP3758-5151-7-56BC-CU is a brush-type DC motor manufactured by Pacific Scientific within the Permanent Magnet DC Motors series. Designed for industrial automation, the unit translates armature current into steady shaft torque for material handling, packaging, or positioning machinery. Its removable base supports foot installation, while the 56C frame provides a NEMA C face for direct coupling to reducers or pump heads. A totally enclosed non-ventilated enclosure shields the winding against airborne contamination without relying on external airflow.
At its nominal operating point, the motor operates from 90 V DC and sustains 7.0 A of armature current, producing 27.0 lb-in of continuous shaft torque. The resulting speed is 1750 rpm, a standard rating that simplifies pairing with gearboxes and speed controls designed around 1,750 rpm bases. With a torque constant of 4.15 lb-in/A, each additional ampere delivered by the drive contributes a predictable increment in output torque, easing current-mode control loops. Armature inductance of 3.8 mH moderates current rise, helping limit brush arcing during fast reversals, and the rotor inertia of 8.0 lb-in supports smooth acceleration without excessive overshoot.
For short-term demands such as indexing or load spikes, the armature can accept 113.0 A, giving several times rated torque before thermal limits are reached. Internal copper resistance of 0.74 Ω affects I2R heating and should be considered when sizing power supplies for surge duty. The overall mechanical output capability is 3/4 hp, delivered through the keyed shaft, and the 14.0-inch body length provides adequate surface area for natural convection. Even at this power level, the motor weighs just 36 lb, so slide axes or gantry carriages can carry it without excessive reinforcement, especially when the detachable base is removed for face mounting.
