Product Description:

The BA3628-7012-9-56BC is a permanent-magnet DC motor produced by Pacific Scientific within the Permanent Magnet DC Motors series. It is built to convert low-voltage direct current into steady rotational energy, letting machine builders drive compact conveyors, indexing tables, or linear actuators without the complexity of an AC inverter. The motor’s NEMA 56C face simplifies alignment in standardized gearboxes, while the totally enclosed, non-ventilated enclosure protects the armature from airborne dust encountered in many automated assembly or packaging cells.

This model operates on a rated armature supply of 24 V, and under that voltage it reaches a rated speed of 1750 RPM. At that operating point, the armature draws a continuous current of 19.5 A, a value that helps size fuses and conductors in the control cabinet. The motor develops a continuous shaft torque of 18.0 lb-in, providing predictable load acceleration when paired with a suitable gear ratio. Armature heating is influenced by the low resistance of 0.10 Ω, so conductors must dissipate I²R losses efficiently. The 4.500-inch pilot diameter centers the frame, and the 0.188 × 1.38-inch key secures couplings against torsional shock.

The motor delivers 1/2 HP of mechanical output, which is suitable for light material-handling duties that run for long periods without frequent starts. Its electrical characteristics support smooth current transitions when the drive issues speed corrections. A shipping weight of 21 lb keeps installation manageable while still providing enough thermal mass for continuous duty. The hardened steel shaft, ground to 0.6250 in diameter, matches common flexible couplings and belt pulleys, and the overall length of 10.13 in permits placement in tight control cabinets or on multi-axis mounting plates.
