What to do when your motor is obsolete: A roadmap for replacement

Articles

It is a scenario every facility manager in Brisbane dreads: a critical fan or pump motor fails, you look at the nameplate, and the manufacturer has been out of business for a decade.

When you can’t buy a “like-for-like” replacement off the shelf, the temptation is to modify the mounting or the ducting. However, this is often the most expensive and time-consuming route. At Edington Agencies, we specialise in the “Cross-Reference” — finding a modern, high-efficiency equivalent that fits your existing footprint.

The Edington Roadmap to Replacement:

  1. Frame Size and Mounting: We start by identifying the IEC frame size or the specific NEMA mount. If it’s a bespoke HVAC motor (like an old Fasco or GE model), we look at the “belly-band” or stud mounting details.
  2. Electrical Characteristics: We match the kilowatts (kW), speed (RPM), and voltage. In many cases, we can upgrade you from an older, inefficient motor to a modern MEPS-compliant Marathon or WEG unit that reduces your energy bill.
  3. Shaft Dimensions: This is where most DIY replacements fail. We ensure the shaft diameter and length match your existing pulley or fan blade precisely.

The Edington Advantage: Don’t waste hours scrolling through catalogues. Send us a photo of your motor’s nameplate and a quick measurement of the shaft. Our Coorparoo warehouse is stocked with thousands of alternatives specifically chosen for the Australian market.
