In this paper, we present the development of a high-efficiency electronic commutated (EC) motor using nonoriented electrical steel produced by China Steel Corporation for window-type air-conditioning system applications. The EC motor combines the highly efficient brushless DC electric motor, Hall-effect sensor, driver, and AC/DC converter, but it has similar volume and equivalent performance to the traditional AC motor. By analyzing the material properties and using simulation tools, an EC motor with a high efficiency of about 82–86.4% is demonstrated in this study. A system manufacturer can replace the AC motor with an EC motor directly in the air-conditioning system for higher performance and save more energy, without altering the mechanical design.
