Many manufacturers underestimate how quickly water ingress can lead to motor rust and cascade into costly performance failures. When moisture penetrates seals or housing, it does more than cause superficial corrosion—it actively damages the core electrical and mechanical components that drive your device. In this article, we’ll explore the mechanisms behind water ingress and motor rust, why this issue is often overlooked, and what manufacturers can do to prevent long-term damage. How Water Ingress Starts Water ingress describes any unintended infiltration of moisture into a device’s interior. This can occur through: Micro-cracks in the casing Worn-out gaskets Improper assembly Capillary action along wiringEven small amounts of condensation or splashes can gradually accumulate inside enclosed spaces, creating a humid microenvironment ideal for corrosion. Why Water Ingress Accelerates Motor Rust When moisture reaches the motor assembly, several problems emerge: Oxygen and water react with metal surfaces, forming rust on motor shafts, bearings, and laminations. Rust disrupts smooth rotation, increasing friction and energy consumption. Corrosion can also lead to pitting and structural weakening.Once motor rust has started, it’s difficult to reverse without replacing parts entirely. Early Warning Signs of Moisture Damage Recognizing the symptoms before failure occurs is critical. Watch for: A grinding…
