How to Identify a Reliance DC Motor
Founded in 1904, Reliance Motors are manufactured by the Baldor Electric Company, a major manufacturer of electrical engines for industrial use. Reliance Motors began with manufacturing direct-current, or DC, motors, because alternating-current was considered dangerous at the time. The variety of Reliance Electric Motors includes different sizes, applications, voltage requirements and numerous other specifications, some of which are custom designed, depending on the intended use of the motor. Identifying Reliance DC motors requires locating the Baldor Identification nameplate found on the motor housing.
Instructions
- 1
Find the Baldor/Reliance identification nameplate on the exterior of the motor. The ID nameplate is normally riveted to the motor in an obvious location, with the Baldor/Reliance corporate name featured on the top of the nameplate. You may need all of the information found on the nameplate to narrow down the possible motor options.
2Locate the Baldor/Reliance model and frame numbers on the identification nameplate. The nameplate contains a variety of codes and specifications, each with an identifying heading. The Reliance model and frame numbers are normally found at the top of the name plate, under the Reliance Electric corporate name. Example numbers are: frame "C1811ATCZ" and model "T18R1009."
3Reference the Baldor/Reliance model and frame numbers to the Baldor DC motor catalog. Locating the Reliance DC motor model number in the Baldor catalog will further identify the motor in question. A motor with the frame number "C1811ATCZ" and model number "T18R1009" is identified as a RPM III Shunt Wound SCR drive motor, with 240V armature, 240V field and power code C, when referenced in the Baldor Catalog. If the model number is not available in the catalog, you can reference the motor using the the frame number.
