1/4 HP Three-Phase Motor for Industrial Machinery
The Baldor-Reliance CNM3454/35 is a 1/4 horsepower three-phase motor built for general-purpose industrial machinery. Its 56C frame with C-face mounting suits direct-coupled equipment such as pumps, gearboxes, and conveyors. Rated for 230/460 V AC at 60 Hz, it draws 0.8 A at low voltage and 0.4 A at high voltage.
Totally Enclosed Non-Ventilated Continuous Duty
The totally enclosed non-ventilated enclosure dissipates heat through the steel frame without external airflow, making it suitable for dirty or damp environments. Class F insulation and a 1.15 service factor allow sustained operation at full load within a 40 °C maximum ambient temperature. Nominal efficiency is 80 percent at 1750 rpm nameplate speed.
Fixed-Speed 60 Hz Line Operation
This motor runs directly from three-phase mains at 60 Hz, delivering constant 1750 rpm output with no variable-speed capability. Rotation is reversible between CW and CCW by swapping any two supply leads. Thermal protection is not built in, so external overload devices are required. The design carries CSA and UR markings for compliance in applicable jurisdictions.

Questions about this item
How hot does the 1/4 HP 56C motor run at full load in a 40 °C ambient?
The motor is rated for continuous duty at a maximum ambient temperature of 40 °C with Class F insulation, so winding temperature stays within design limits during all-day operation.
What supply voltage and starter gear are needed for the 230/460 V three-phase windings?
A three-phase 230 V or 460 V, 60 Hz supply and a correctly sized motor starter or contactor with overload protection matched to the 0.8 / 0.4 A full-load current are required.
Will the 56C face mount and 1.15 service factor let it replace an older 56-frame motor on the same gearbox?
Yes — the 56C C-face and standard shaft dimensions match legacy 56-frame mounts, and the 1.15 service factor provides the same overload margin as most vintage units.
