Product Description:

The BA3624-7024-9-56BC is a permanent-magnet DC motor manufactured by Pacific Scientific for its Permanent Magnet DC Motors series. Designed for fixed-voltage drives in automated conveyors, packaging lines, and light machining axes, the unit converts electrical energy into continuous rotary motion with high torque density. A totally enclosed non-ventilated housing isolates the windings from airborne oil or dust and permits installation in cabinets where external airflow is unavailable. The front-face pilot and bolt-circle dimensions allow direct coupling to gear reducers, pulleys, or timing-belt assemblies in industrial equipment.

The motor draws a continuous armature current of 13.4 A to develop a sustained output torque of 12.0 lb-in without exceeding its thermal limits. When supplied with 24 V DC, the armature reaches the rated speed of 1750 RPM, meeting the speed requirements of belt-driven feeders and light conveyors. A 5.875-inch bolt circle, a 4.500-inch pilot diameter, and 3/8-16 UNC-2B tapped holes locate and clamp the end bell precisely on the host machine frame, minimizing runout in inline powertrain assemblies.

The motor’s mechanical output is limited to 1/3 HP, which suits fractional-horsepower drives often powered from battery banks or low-voltage supplies. Armature circuit resistance of 0.16 Ω restricts stall current and must be included in drive fault calculations, while the winding inductance of 0.66 mH filters current transients generated by pulse-width-modulated controllers. A torque constant of 1.02 lb-in/A provides a linear relationship between commanded current and developed torque for closed-loop control. The 0.6250-inch diameter shaft is furnished with a 0.188 × 1.38-inch key, enabling secure torque transmission to couplings. The overall length is 9.13 inches, and the frame weighs 19 lb, which affects mounting orientation and dynamic loading on lightweight equipment.
