This 16-page brochure from Baldor Electric Company (Forth Smith, AR) describes how electric motor efficiency is measured and how this relates to the company's products. Other topics include premium efficiency and how it pays for itself, and how variable-speed drives can help attain additional savings. Also included is a mini CD-ROM with the company's Save+ software that compares the annual operating costs of three different industrial electric motors based on their efficiency ratings and operating cycles and gives a financial summary of the annual savings and payback in months for each.
