Chemical and manufacturing industries spend upwards of 10% of their budgets on energy and replacement of electric motors, and these are seen as fixed costs. The energy usage of various electrical motors will vary as the motors age and oxidize. The application of Volatile Corrosion Inhibitors to protect electric motors from oxidation was examined. When the copper windings and other internal components oxidize, their energy usage will generally increase and their useful life will decrease. Utilization of Volatile Corrosion Inhibitors to protect electric motors before and during operation could potentially provide a substantial cost savings to almost any company in chemical and other manufacturing sectors. ASTM B 117 salt spray proved to have a significant effect on the resistance of an untreated electric motor, whereas various volatile corrosion inhibitor products prevented the motors from oxidizing.
