“…The size of flux barriers affect the amount of magnetic flux in the rotor both in d and q axis. Thin flux barriers reduce the reluctance in d axis which makes the Ld inductance grow, but at the same time Lq inductance increases [16][17][18][19].…”

In order to define the best design structure of the synchronous reluctance motor (SynRM) rotor, optimization must be carried out, implying the selection of the best alternative for each specific criterion. The optimization of an electrical machine is a complicated work involving meeting different criteria requirements while dealing with a range of constraints. In order to implement the optimization, it is necessary to process a huge number of options, changing the combinations of the factors affecting criteria and restrictions, which is a time-consuming process. This research presents the optimization technique that gives a mathematically proven solution of the optimal rotor design of a synchronous reluctance machine obtained by using metamodels in the form of local polynomial approximations. Analysis of the results of numerical modeling and experimental investigation has been performed in order to validate the developed technique and recommendations. SynRM rotor was manufactured, with the stator to be taken from the 1,1 kW W21 WEG induction motor, which makes possible the relevant experimental study. The performance analysis of the developed SynRM is shown in the paper.

“…However, the motor's electronics are different in that they control which phase of the stator current is applied depending on the position and direction of rotation. EC motors have many advantages (11)(12)(13)(14)(15) such as very high efficiency, integrated control (continuous control), very simple plug-and-play connection, and additional functions through the addition of accessories (e.g., control of pressure, flow, speed, temperature, and air quality, tachometer, and alarms). They also have a smaller size, the same performance as AC motors, and lower energy costs, and they are suitable for all countries worldwide.…”

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.
