Storage requirements for motors and generators that will not be placed in service for at least six months from date of shipment. Improper motor storage will result in seriously reduced reliability and failure.
For practical reasons, these are governed by the motor's size and how long it will be out of service. Factors like temperature, humidity and ambient vibration in the storage area also influence the choice of storage methods, some of which may be impractical for smaller machines or need to be reversed before the motor goes into service.
Motors slated for several weeks to several years in storage (as well as all above-NEMA-sized machines) require additional preparations to protect their machined surfaces, bearings and windings. When possible, store motors indoors in a clean, dry area.
Store electronic copies of the previous forms for future reference, or simply keep them in an envelope attached to the motor. Short-term storage. Motors that will be in storage for just a few weeks primarily require protection from the weather (see “Indoor storage” and “Outdoor storage” below) and ambient vibration (more on this later).
Outdoor storage. Don't! Seriously, if a motor is too large to store indoors, it is likely to be a very expensive machine. It's worth the cost to construct an enclosed storage facility. When outdoor storage is absolutely necessary, protect the motor with a waterproof cover (e.g., a tarp), allowing a breathing space at the bottom.
