Electric Motors and Variable Speed Drives at the Hospitals: An Overview
40% of total world electricity consumption is approximately consumed by electric motors. Researches show that, hospitals represent approximately 6% of total energy consumption in the utility buildings sector. Electric motors in a hospital represent approximately 19% of the total energy consumption. In this paper, the research papers and practical studies on energy efficiency and energy saving potentials on electric motors at the hospitals are presented. Under the following sections, the latest literatures including research articles, conferences, e-books, handbooks, reports, web pages, MSc and PhD theses interested in energy efficiency, energy saving and energy management on electric motors are summarized. Payback period calculations of some projects on electric motors are also presented.
