Understanding Baldor Catalog Numbers: A Motor Selection Guide

Each electric motor manufacturer has their own format for part numbers, which can make finding a replacement motor challenging. In this article, we will attempt to shed light on the method that the ABB Baldor Reliance Company uses to label their products. 

At first appearance, Baldor catalog numbers look more like secret codes rather than formatted part numbers. L3510T, KBL3409, VECP83583T-4... they're enough to make your head spin.

But we're here to tell you that Baldor catalog numbers are actually not difficult to interpret. All you need is the key, and soon you'll be cracking the codes like a pro!

In this expanded guide, you’ll learn:

  • How to identify a Baldor catalog number
  • How to break down prefix, body, and suffix codes
  • Practice examples of decoded numbers
  • Industries that use Baldor Reliance Motors
  • How to match replacement motors with confidence

Baldor Catalog Numbers

Baldor catalog numbers are unique alphanumeric codes that identify a motor’s design, performance, specifications, and intended use.

Baldor 501 Catalog

A typical Baldor number has three main parts:

  1. Prefix – Letters that describe the motor’s type, duty, or features
  2. Body – A set of numbers (often non-significant) representing the model series
  3. Suffix – Extra letters or numbers describing voltage, frame size, mounting, or design modifications

📌 Example: L3510T

  • L = Single phase motor (prefix)
  • 3510 = Model identifier (body)
  • T = NEMA “T” frame (suffix)

Having the code key is a useful tool to decipher the part number and make searching for your replacement Baldor motor easier.

🔠 Baldor Suffix Codes

While prefixes describe what type of motor it is, suffixes tell you how it’s built. These details make a big difference when sourcing a replacement.

🔌 Voltage & Winding

  • -4 = 460 volt winding
  • -5 = 575 volt winding
  • -50 = Wound for 50 Hz service
  • -2340 = 2300/4000 volt winding

🧰 Frame & Mounting

  • T = NEMA T-frame motor
  • TR = T-frame with roller bearing
  • TS = T-frame short shaft
  • H = 56H mounting

⚡ Electrical Features

  • C = IEC B14 face mount
  • D = IEC B5 flange mount
  • E = New electrical design
  • M = Manual thermal overload
  • A = Automatic thermal overload

🌧️ Environmental Protection

  • EX1, EX2, EX3 = Explosion-rated designs
  • E = Encapsulated windings
  • NL = Non-linear load (for VFD use)

⚙️ Mechanical Enhancements

  • CI = Cast iron frame
  • G = Shaft grounding ring
  • L = Long shaft, convertible
  • BG = Shaft ground motor (Baldor Reliance)

Real-World Example: Decoding a Baldor Number

Let’s decode EM3615T-4:

  • E = Super-E premium efficient
  • M = Three phase motor
  • 3615 = Model series
  • T = T-frame mounting
  • -4 = 460V winding

👉 This is a three-phase, premium efficiency, T-frame Baldor motor designed for 460 volts.


💡 Why Catalog Number Knowledge Matters

Understanding Baldor catalog numbers is not just a neat trick—it’s a critical maintenance skill.

Match replacement motors exactly to OEM specs
Avoid incorrect purchases that waste time and money
Reduce downtime by ordering the right unit the first time
Improve efficiency with the correct enclosure and winding type

For facilities that rely on uptime—like factories, data centers, or hospitals—knowing how to decode catalog numbers can be the difference between smooth operations and costly delays.


🛠️ Maintenance Tip: Don’t Forget Bearings

Did you know that more than half of motor failures are caused by bearings?

Baldor designs motors for long life, but regular lubrication, proper alignment, and correct VFD programming (for inverter duty models) all help maximize motor performance.

The L10 formula, used by the bearing industry, predicts life expectancy based on RPM, load, lubricant, and bearing type. Keeping an eye on these variables ensures your Baldor motor runs longer.
