Non-Magnetic, Fully Customized
Defense-Spec Electric Motors for Naval Use

We were commissioned to design and manufacture two electric motors, frame size 160, intended for operation on board a navy vessel. The challenge: the motors had to be free of magnetic materials on their external surfaces, in compliance with special defense specifications.

To meet these requirements, we implemented a range of non-magnetic material solutions, including:

• Aluminum motor frame

• AISI 316 stainless steel shaft

• All screws and lifting lugs made from AISI 316

• A custom-designed polyester fan cover, reinforced with an AISI 316 air inlet

To ensure fit and finish, we even created a dedicated mold for the polyester fan cover—crafted entirely in-house. In the final photo, you can see (from left to right):

All this—for just two motors.

Because we care about the details, and we love creating specials.
