H&N Electric™ offers an electric motor storage program specifically designed to keep spare motors safe, secure, and in working order. With ample, environmentally-controlled space and expert monthly maintenance, we ensure your electric motor spares are ready at a moment’s notice for reliable swaps when you need them most.
Why store your motor spares with H&N?
Proper industrial motor storage accounts not just for availability. It’s about ensuring your spares are maintained on a fixed schedule by technical experts who understand how to limit damage and corrosion while providing fast turnaround ¬— all at a reasonable price.
With H&N’s motor storage program, you get:
- A temperature- and humidity-controlled storage facility that adheres to all FME procedures and prevents rust on shaft and bearing components due to wide temperature swings
- Timely rotation of the motor shaft to reduce false brinelling on bearings
- Periodic insulation resistance (or MCE tests) to monitor for degradation of the insulation system and assure reliability when the electric motor is returned to service
- Preventative maintenance activities, including periodic electrical testing, shaft rotation, heater checks, and temperature monitoring (when applicable).
- Quarterly customer storage reports
Proper motor preservation and storage
Correctly storing motors, bearings, shafts, and other critical equipment involves a variety of important mechanical and environmental considerations. Before you choose any long term motor storage solution, consider the following:
- A clean, dry, climate-controlled, and vibration-free area
- Horizontal motors should be stored in a horizontal position and vertical motors in a vertical position
- Facility must exclude rodents, insects, birds or other small animals that could cause damage to equipment
- Rust-preventative coating should be applied to exposed surfaces
- Motors in tropical environments should receive a topical fungicide
- Motor shafts should be rotated periodically to prevent bearing damage. Shaft rotation keeps the balls and raceways coated and prevents false brinelling. The shaft should be locked to prevent movement.
- Grease-lubricated bearing cavities in stored motors should be filled completely prior to storage and inspected periodically for contamination and moisture
- Grease-lubricated bearings may require relubrication at specific intervals during storage to avoid grease dry-out. If a motor is stored for an extended time without proper maintenance, the grease can harden or oxidize.
- Motors with oil should receive oil changes and visual inspections for FME
- Motor windings must be kept clean and dry at a stable temperature to prevent insulation breakdown
- If a motor cannot be stored in a climate-controlled storage area, motor heaters should be used to prevent condensation inside the motor
- Periodic resistance testing should be performed to monitor degradation of the insulation system
