    Which of inv-duty motors w/VFD is prefarable - increasing or reducing

    Sorry if this is a dumb question but wouldn't a 2 pole motor at 60hz with the same HP give you the same rpm result as the "trick" above and the 2 pole motor is a cheaper motor.

    Motor Reliability Statisitcs

    Shortstub, I'm interested in the PRA study as I'm involved in a new installation with HV switchgear, transformers etc. If I could locate areas that need to be inspected better it would be helpful. Perhaps you could provide me with a link thanks.
