Product Description:

The EP3632-1435-7-56BC-CU is a permanent-magnet DC motor produced by Pacific Scientific and supplied within the Permanent Magnet DC Motors series. As a brushed DC unit, it converts electrical energy from a fixed-voltage supply into continuous rotational motion for actuating conveyors, indexing tables, or machine tool axes. Within an automation cell, the motor pairs with a DC drive or thyristor speed controller, allowing compact speed regulation while maintaining torque at low speeds. This arrangement supports smooth speed changes during start-up, indexing, and low-speed transport in compact industrial machines.

At its rated operating point, the motor accepts a supply of 90 VDC and draws a continuous armature current of 3.5 A. Under these conditions it delivers 12.0 lb-in of steady torque while spinning at 1750 rpm, providing a mechanical output of 1/3 hp at the shaft. The totally enclosed non-ventilated enclosure limits airflow but shields the windings from airborne dust, so heat generated at the rated load is conducted through the steel frame. Because the motor maintains torque proportionally with current, the drive can trim speed without sacrificing usable force for web handling or small hoists.

During acceleration, the armature can tolerate a surge of 71.0 A, giving short-term torque several times the continuous rating. Electrical time response is influenced by the armature inductance of 6.6 mH, which moderates current rise when the drive applies a step voltage, while the resistance of 1.76 Ω sets the steady-state current for a given command. A torque constant of 3.94 lb-in/A links these electrical parameters to mechanical output, which helps support closed-loop control calculations. With a NEMA 56C frame, C-face mount, 11.38-inch overall length, and 27-pound mass, the motor installs directly onto gear reducers or pump heads without additional adapters.
