Product Description:

Pacific Scientific manufactures the BA3618-7009-9-48B permanent-magnet DC motor for its Permanent Magnet DC Motors series. The unit converts low-voltage direct-current power into rotary motion for machine tools, indexing tables, and light conveyor sections in industrial automation. Permanent magnets built into the stator eliminate separate field wiring, and the brushed commutation scheme allows direct connection to simple DC speed controllers used in many legacy systems. That arrangement also supports straightforward speed variation and predictable torque in compact motion assemblies where AC drives are not required.

The motor has a continuous torque rating of 9 lb-in, allowing stable drive of belt or gear-reduced loads without overheating. At that load, the armature draws 10.3 A, which helps determine suitable protection and conductor size. Copper windings present an armature resistance of 0.14 Ohms, so voltage drop and thermal losses remain limited during steady operation. A winding inductance of 0.57 mH slows current rise in a controlled way, which can reduce ripple in pulse-width-modulated operation. The motor operates from a nominal bus voltage of 24 VDC, making it suitable for common DC power supplies and battery-based equipment.

The motor has a base speed of 1750 RPM, which matches the shaft output of many gearboxes and centrifugal devices. The housing is a totally enclosed non-ventilated design rated TENV, so heat leaves through the frame while airborne debris stays outside the enclosure. This layout also helps keep internal components cleaner during routine operation. Overall length is 9.13 in, which helps the unit fit into compact machine spaces where clearance is limited. The assembly weighs 18 lb, giving the frame enough mass for stable mounting and continuous-duty operation.
