Product Description:
The BA3644-4249-1-48C motor is a permanent-magnet DC unit manufactured by Pacific Scientific and supplied in the company’s Permanent Magnet DC Motors series. It serves as a compact torque source for industrial automation, turning constant-voltage power from a drive or rectified supply into bidirectional shaft motion that can be finely regulated by the connected controller. Because it develops torque directly from the armature current, the motor is suited for conveyors, feed rolls, and indexing mechanisms that demand steady speed and prompt reversal without an external field winding.
The continuous armature current limit is 28.2 A, establishing the maximum load it can carry indefinitely without exceeding its thermal rating. When operated at that current, the motor delivers 27 lb-in of continuous shaft torque for sustained duty cycles. A totally enclosed, non-ventilated enclosure classified as TENV keeps internal parts free of dust and oil while relying on the housing surface area for heat dissipation, a layout that simplifies installation where forced airflow is unavailable. Electrical dynamics are characterized by an inductance of 0.22 mH. This low value allows rapid current changes so speed and torque settle quickly after command steps. The armature is machined with a shaft diameter of 0.6250 in with a -0.0005 tolerance to interface directly with couplings or pulleys without additional machining.
Mounting follows NEMA C-face conventions, with a flange outside diameter of 6.50 in and a bolt circle of 5.875 in for four evenly spaced fasteners. Those fasteners engage tapped holes specified as 3/8-16 UNC-2B, allowing quick attachment to gearboxes or pump brackets. A pilot diameter of 4.500 in with a 0 to -0.003 in tolerance and a maximum pilot length of 0.16 in center the motor precisely on the driven equipment. Output torque is transferred by a keyed connection, and the key measures 0.188 × 1.38 in to provide positive drive and resist slip under full rated load.
