Aluminum electric motors are increasingly becoming the standard. They are easier to produce, more manageable, and there is no difference in motor performance. However, in the maritime industry, this is viewed with raised eyebrows.
You can see in the market that aluminum electric motors are increasingly becoming the standard. They are easier to produce and there is more demand for them because they are lighter and therefore more manageable. In terms of motor performance, it makes no difference; only the housing is aluminum. This is why housing sizes from 132 to 160 are increasingly made of aluminum.
However, in the maritime industry, this is viewed with raised eyebrows. Not without reason, because aluminum exposed to harsh weather conditions and salty seawater corrodes faster and thus wears out sooner. For this reason, we still keep the heavier cast iron variants in stock.
But how great would it be if we could combine the advantages of the aluminum variant with those of the cast iron variant? Then you would have a lighter, more manageable electric motor that lasts as long as the cast iron motor. Moreover, less weight on board means less energy consumption.
That's why we took on the challenge and treated an aluminum motor, intended for a fishing boat, with Kolmer Top Coating two years ago. This ultra-hard, wear-resistant coating anchors itself through the paint layer into the metal, in this case, aluminum. As a result, no dirt or moisture gets under the paint layer, so the motor is not damaged.

This aluminum electric motor from Cantoni, coated with Kolmer Top Coating, has been on the bow of a fishing boat for two years, exposed to weather, wind, and seawater. The motor is slightly scuffed, but these are just signs of use. The housing is completely intact. Our customer was so satisfied that he ordered more aluminum Cantoni electric motors with Kolmer Top Coating: an IEC 80 and a brake motor. For this customer, it proved to be a success.
