“…Recently, permanent magnet brushless DC (PM BLDC) motors are being widely used. (1)(2)(3)(4)(5)(6)(7)(8)(9) These motors have many advantages, such as having a rotor without additional windings or brushes, simple structure, high operating efficiency, and easy maintenance. Compared with AC motors that provide traditional commercial power, BLDC motors must also have a Hall-effect sensor and a power converter as an intermediate medium.…”

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.
