Baldor-Reliance CDP3440 DC Servo Motor

The Baldor-Reliance CDP3440 is a 0.75 horsepower DC permanent-magnet motor designed for general‑purpose industrial service. Configured in a 56C-frame, this brushed DC motor uses a totally enclosed, fan‑cooled (TEFC) enclosure and is built for continuous duty in demanding shop environments. The base configuration runs from a 90 VDC supply at roughly 1,750 rpm, delivering typical performance for light-to-moderate loads, and Baldor also offers low‑voltage variants CDP3440-V12 (12 V) and CDP3440-V24 (24 V) that operate at about 1,800 rpm in their respective builds. Shaft options vary by variant, with the base model listing a 3428P shaft and the low‑voltage versions using 3424P or 3430P configurations depending on the exact build. The motor lead exits through a KO box for convenient wiring. Classified as a general‑purpose DC motor in Baldor’s catalog, the CDP3440 family is commonly used in drives, feeders, conveyors, and light machine tools where a compact, 56C, brushed PM motor is advantageous.
