When an electric motor will be stored a long time before being placed in service, you must take certain steps to ensure it will be suitable for operation when it’s needed. One practical limitation to recognize is that much of what is done when preparing a motor for long-term storage must be undone when it is moved into operation. Storage procedures generally depend on the size of the motor and whether it will be out of service short term (several weeks) or long term (several months).
