Product Description:
Pacific Scientific manufactures the BA3614-4648-9-56BC direct-current motor as part of its Permanent Magnet DC Motors series. The unit is a brush-type actuator that converts low-voltage electrical energy into constant rotation for conveyors, indexing tables, and other position-independent drives in automated equipment. Its permanent-magnet design also supports simple speed control from a DC supply without requiring a separate field circuit. By supplying steady torque from a compact NEMA 56C frame, the motor serves as a straightforward power element that couples to gearboxes or pulleys without additional electronics.
Electrical ratings describe how the motor should be driven. A nominal input of 12 V lets the winding draw up to 21.1 A continuously, a pairing that produces 9.0 lb-in of shaft torque during steady operation. The electromagnetic conversion is characterized by a 0.51 lb-in/A torque constant, meaning each ampere adds roughly half a pound-inch of torque. Low copper losses come from an armature resistance of 0.07 Ω, while dynamic response is aided by an armature inductance of 0.27 mH. Mounting geometry follows the 56C pattern with a 5.875-inch bolt circle, a 4.500-inch pilot, and a 6.50-inch flange that centers the housing on gear reducers. Power is transmitted through a 0.6250-inch keyed shaft that accepts a 0.188 × 1.38-inch key.
The enclosure and overall size suit tight installations. The totally enclosed non-ventilated casing is classified as TENV, so heat dissipates through the steel shell without external airflow. Within its overall length of 8.13 inches, the machine delivers 1/4 HP at rated speed, aligning with fractional-horsepower drives that favor battery or low-voltage supplies. Mass is held to 15 lbs, reducing inertia when the motor is mounted on adjustable slides or lightweight frames. The NEMA 56C face, combined with the previously noted pilot and bolt circle, simplifies interchange with standard reducers, while the keyed 0.6250-inch shaft helps keep couplings from slipping under continuous torque.
