Electric motors used outdoors are susceptible to temperature extremes and moisture build up, leading to internal corrosion that quickly shortens motor life, causing early motor failure. However, a new approach to preventing corrosion and early failure uses a system of rugged corrosion proof coatings that are applied to all metallic surfaces both inside and outside the motor, protecting them from moisture and corrosion.
The traditional solution to corrosion problems was to seal the motor in order to keep out moisture that leads to internal corrosion. Shaft seals and end cap/housing seals will delay, but not stop, the penetration of moisture into the motor. Moisture will eventually find a way through any seal helped by temperature variations. Once the moisture is inside the motor, the seals act as a barrier to any removal of the moisture. In addition, shaft seals typically cause a loss of 3 to 15% of shaft torque due to rubbing friction. Also, because motors repeatedly go through cycles of heating and cooling, the air inside the motor expands and contracts. As the air inside the motor contracts, a small amount of moisture is sucked inside the motor. This eventually leads to some internal corrosion, to which hybrid step motors are particularly susceptible.
The coatings that were previously used were not rugged enough to protect the soft-iron magnetic and metallic materials inside a step motor over its design life. The new technique applies the coating to every surface and structure inside and outside the motor, including the rotor, stator, and housing. It essentially coats every one of the surfaces that could potentially rust, such as steel and aluminum. The material selections and coatings are tailored for each motor component. For example, the permanent magnets, aluminum endbells, and steel laminations use coatings, and upgraded base materials as needed to protect the parts from corrosion, while maintaining motor performance.
• Testing Standard: American Standard MIL-STD-202G salt spray test
Verifying the corrosion proof properties of the new coatings involved reviewing the available salt atmosphere or spray tests used extensively by the industrial and defense industries. MIL-STD-202G, test method 101E, is an all-purpose accelerated corrosion test, and the toughest corrosion test for commercial and industrial applications. Even though it is a military standard, it is still useful for commercial and industrial applications, a notable difference being the absence of any altitude requirement. This corrosion test format and procedure was used to evaluate the corrosion proof capabilities with one important change. The test was extended to 240 hours continuous testing. This condition is higher than all specified test conditions, except for one used primarily by the defense industry itself.
