Study of a Novel Energy Efficient Single-Phase Induction Motor With Three Series-Connected Windings and Two Capacitors

Comparison of Electromagnetic Characteristics of Single-Phase Induction Motor between Balanced and Unbalanced Operation under Different Loads

“…The former usually can be solved by utilizing the various frequency inverter to adjust the supply frequency [9][10][11]. The latter can be achieved by the pole changing method or adding multiple capacitor with poly-phase windings [5][6][7][8]12].…”

“…They developed improved SPIMs by geometrical changes [5][6][7][8], and adapting control strategies of an electronic circuit [9][10][11]. In addition, some studies [12] have suggested operating scheme of SPIMs using three-phase windings where the two capacitors are used to operate from single-phase supply. The additional winding and capacitor lead to a higher degree of freedom to make the operating performance approximately same as threephase induction motor.…”

100 Years of Symmetrical Components

“…A quite extensive modelling of the IM in symmetrical components for efficiency studies in unbalanced supply conditions was presented in [63]. The performance of the IM supplied from one-phase system was studied with the symmetrical components in [64]: the authors suggested a new schematic, providing the methodology for calculating the values of capacitances for guaranteeing higher efficiency than the ordinary single-phase IM.…”

Design methods for high power density permanent magnet motors and high efficiency induction motors

“…There are more than twenty PSO variants available in the literature. Indicatively, it is mentioned that the explorative PSO (a modified version of the original one combined with a mesh adaptive direct search) was suggested in [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] for the PMSMs design. This method diminishes substantially the search time.…”

“…The precision of the acquired solution is high even when the examined problems include simultaneous air-flow and mass transfer with a mix of laminar and turbulent states [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The losses of the machine are considered as surface heat flux or constant surface temperature boundary conditions [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The CFD analysis has become more popular in the last few years due to its advantages.…”
