Product Description:

The BA3618-7009-9-56BC is a permanent-magnet DC motor built by Pacific Scientific for the Permanent Magnet DC Motors series. It supplies mechanical rotation suited to conveyors, indexing tables, and light actuators in automated equipment. A 56C NEMA face and 9.13-inch frame length allow drop-in mounting with gearheads or pumps, giving machine builders predictable speed and torque from a compact DC source. Its permanent-magnet design eliminates separate field wiring and supports straightforward DC motor control.

Electrically, the armature draws a continuous current of 10.3 A from a nominal supply of 24 V, which supports steady operation without overheating. At the rated load, the shaft turns at 1750 RPM, a speed typical for small process equipment that simplifies pulley or gearbox selection. The copper winding resistance is 0.14 Ω, so voltage drop and I²R losses remain low, aiding efficiency during continuous duty. A torque constant of 1.04 lbf-in/A links armature current to developed torque, allowing drive electronics to predict output accurately. Additional parameters include 0.57 mH of inductance, which limits current ripple, and a rotor inertia of 3.2 lbf-in·s², which moderates acceleration. The compact frame also fits inside many panels without encroaching on adjoining hardware.

On the mechanical side, the motor can deliver a continuous shaft torque of 9.0 lbf-in, and that output corresponds to a rated power of 1/4 HP. The totally enclosed non-ventilated housing, designated TENV, keeps out dust and moisture and relies on surface conduction for heat removal, so additional airflow is not required. Overall mass is 18 lb, which is light enough for wall-mounted panels while still helping reduce vibration from the driven load. This enclosure style also avoids drawing outside air through the motor interior during operation.
