Epoxy Resin Putty for Balancing Electric Motors

Weicon Epoxy Resin Putty Balancing Electric Motor

When we found out one of the highest-selling products from our Weicon line was none other than Epoxy Resin Putty, we became curious to know what our customers were using it for. After all, there are so many uses for this universal repair epoxy. It can be used to repair, fix, seal, patch, anchor, mould and balance. However it was the last one, ‘balancing’ that kept popping up when we spoke with many of our customers and we must say the feedback we have received about the product for this application has been overwhelmingly positive.

So what is balancing? It has to do with electric motors.

Inside all electric motors is what’s known as a rotor. This is the part that rotates due to the interaction between the windings and the magnetic fields. A rotor can become unbalanced from either fixed (non-symmetrical design or manufacture) or variable sources (shifting or distortion during use). Unbalance in an electric motors is a problem as it generally causes vibration, wear and tear on the bearings and inefficient operation, which means it needs to be fixed, fast! The process undertaken to rectify the problem is known as dynamic balancing.

Balancing Electric Motors with a Hard-Setting, Kneadable Repair Compound

To balance a rotor, Electric Motor Rewinders require a hard-setting epoxy that will bond well to whichever part of the rotor needs to be balanced. This is why they use Weicon Epoxy Resin Putty. It’s a kneadable repair compound that bonds well to most materials including metal, glass, wood, rubber, ceramics, concrete and most plastics and sets very hard (87 Shore D).

To perform the operation, the motor is placed on a balancing machine and rotated with a belt or end drive. The balancing machine is then able to generate a report, telling you how much weight to add and where. To apply the correct amount of weight to the right place, rewinders apply an epoxy compound.

There are several reasons Motor Repairers choose to use Weicon Epoxy Resin Putty over other products. First of all, it’s simple to use. All you need to do is prepare it for use is measure and cut off equal amounts of the two parts (A & B), then thoroughly knead them together. You don’t need to use the whole kit either and can add or subtract while it’s still curing.

Our customers have also made mention of the fact that they really appreciate part’s A & B being coloured differently (blue and yellow) so they don’t get confused which one to use. This is also beneficial as they can tell when the compound is properly mixed because it turns a uniform green colour when ready for use.

They also love the cure time. Epoxy resin putty reaches mechanical strength in just two hours and full cure in 3 hours, which is quicker than many epoxy compounds on the market. It also bonds well to most materials and does this before achieving a fully cured state to make the whole process faster.

Once cured, it is able to be milled, drilled, filed or machined and resists attack from fuels, oils, sale water, most acids and lye.
