Storing an electric motor for more than a few weeks involves several steps to ensure it will operate properly when needed. For practical reason's,...
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.
It is common knowledge to those involved in the electric motor storage business that maintenance philosophies and procedures vary. But getting it right isn’t that complicated. Here are four key variables that EASA and RSAW found when looking at seven different motor manufacturers and the similarities and differences from each source. They are:
No standard yet exists for defining what a motor owner should do to protect assets placed in long-term storage. It’s probably best to take a conservative approach and begin with a review of the storage standard of the manufacturer of the machine.
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.
It’s probably best to take a conservative approach and begin with a review of the storage standard of the manufacturer of the machine. Once this information has been evaluated, a storage review discussion between the motor owner and the storage provider can be held to develop a specific and agreed upon storage plan.
