TITLE: HOW TO CROSS-REFERENCE AND REPLACE OBSOLETE INDUSTRIAL MOTORS
Introduction
You have an old motor from the 1990s. It just failed. You call the manufacturer, and they say, “Sorry, that model is obsolete.” Don’t panic. At CTCMOTOR, we specialize in finding modern equivalents for discontinued units.
1. The Holy Grail: The Nameplate
Before you do anything, take a clear photo of the motor nameplate. This is the motor’s DNA.
- Key Data Points: Frame Size, Voltage, RPM (Poles), and Mounting (Foot/Flange).
- Tip: If the nameplate is rusted, look for stamped numbers on the drive end.
2. Frame Size is King
The “Frame Size” (e.g., IEC 132M or NEMA 215T) dictates the physical dimensions: shaft height, shaft diameter, and mounting hole distance.
- If the new motor has the same frame size, it will mechanically fit 99% of the time, even if it is a different brand.
3. Efficiency Upgrades
Old motors were likely IE1 or IE2. New motors are IE3 or IE4.
- Watch Out: Newer high-efficiency motors run cooler but might be slightly longer physically. Ensure you have space in the cabinet or machine housing.

4. Brand Switching
Did you know a Siemens motor can often replace an ABB motor if the specs match? We help you cross-reference brands to find the best price and fastest delivery.
