Baldor Electric Company CM3539 Three Phase AC Motor

CM3539 Baldor-Reliance three-phase induction motor delivers 0.5 HP at 1140 RPM in a 56C frame with TEFC enclosure, engineered for general‑purpose industrial duty at 60 Hz. This 3‑phase motor supports 208/230/460 VAC operation and uses a 5/8‑inch shaft, providing roughly 2.3 ft‑lb of torque, with a service factor of 1.25 for light overload tolerance. Mounting options include both C‑Face and foot rigid configurations, making it adaptable to OEM and retrofit installations. Built for continuous duty (class B insulation) in environments up to about 40–76 C ambient, the motor features ball bearings for durability and a compact footprint: roughly 11.35 in long and 9.28 in wide for the 56C frame. Whether used to drive fans, pumps, blowers, conveyors, or machinery in a compact package, CM3539 is a standard Baldor general‑purpose model that aligns with common motor catalogs under the M3539 family, offering reliable, drop‑in replacement compatibility with many Baldor installations.
