Product Description:

The EP3620-4460-7-56C-CU is a permanent-magnet DC motor manufactured by Pacific Scientific and part of the Permanent Magnet DC Motors series. Classified as an explosion-proof unit, it supplies controllable torque for conveyors, mixers, and pump drives operating in hazardous industrial zones where flammable vapors may be present. The motor converts direct current input into mechanical rotation with the consistent torque characteristic typical of brushed PMDC machines, enabling integration with simple DC drives used throughout automated production lines. This operating principle also supports straightforward speed regulation from variable DC input.

Electrical performance is based on a nominal armature voltage of 90 VDC; at that level, the winding draws 3.3 A while producing a continuous output of 1/3 HP. Shaft power is delivered at the rated speed of 3000 RPM, providing a predictable speed-to-torque relationship for closed-loop controllers. A TENV housing, or totally enclosed non-ventilated housing, dissipates heat through the frame instead of using external airflow, which is useful where dust could obstruct vents. Explosion-proof construction uses a thick case and threaded joints to help keep any internal arcs from igniting the surrounding atmosphere. The 4.500-inch pilot centers the frame on the driven machine, and a removable base allows switching between foot and face installations without disturbing alignment.

Mechanical interfaces conform to standard dimensions. The NEMA C Face flange secures the motor on a 5.875 in bolt circle, making it interchangeable with other C-face devices. Field wiring is brought in through a 3/4-14 NPT conduit entry suitable for rigid metallic conduit used in Class I environments. Output torque is transmitted through a 0.6250 in shaft diameter equipped with a 0.188 × 1.38-inch key to prevent slip. With the removable base attached, the motor can be foot mounted for belt applications, and removing the base lowers the center height for compact direct-drive packages.
