Methods differ among small and large motors and for short- or long-term storage

Downtime is costly, so it pays to have spare motors for critical applications. But unless they are stored properly, those spares may not perform reliably when needed.

Storage requirements generally depend on motor size and expected length of storage, so some measures may be impractical for smaller, readily available motors. The recommendations in this article cover most cases, but factors like heat, humidity and ambient vibration may dictate different schedules or procedures. It's important to recognize that some long-term storage procedures must be undone before the motor is placed in service.
