It is common knowledge to those involved in the electric motor storage business that maintenance philosophies and procedures vary. Thorough reviews of available information on the topic of long-term storage from EASA and seven different motor manufacturers revealed some interesting similarities and differences in the information available from each source. Several sources share common elements such as environment, moisture protection, bearing maintenance, and insulation resistance. The purpose of our discussion here is to describe some of the differences and hopefully give some points to consider when creating a long-term storage process for end users.
