Longevity of 120V- vs. 240V-wired motor?

[QUOTE="anorlunda, post: 6521674, member: 455902"] I think the longevity of a motor depends more on (a) mechanical strength and absence of vibrations, (b) effectiveness of aging insulation, and (c) the ability of the windings to resist shifting in their mounts. As a teen, I worked in an amusement park. The roller coaster had a 4HP motor built around the year 1900. It was about 9 feet high and weighed several tons. It ran at 180 RPM (maybe 360). The only maintenance it ever had was a few drops of oil every year. It would be 120 years old today, and it could probably continue another 120 years. [/QUOTE]
