“…According to Refs. [3,4], the three-phase asymmetric induction motor possesses a squirrel cage rotor and ferromagnetic structure of the stator identical to that of the symmetric three-phase induction motor. This possesses only one change on the stator winding that goes on to have a number of different turns per phase, thus maintaining the angular shifts between phases at 120 electrical degrees.…”

This study has as its objective to collaborate with the expansion in the market of electric energy in rural areas, offering as such an innovative prospect to the solution of associated problems through use of the asymmetric three-phase induction motor, supplied by a single-phase source. In this system, capacitor switching is applied during operation, while theoretical and practical results are presented for the application of this switching in a three-phase asymmetric induction motor of 20 hp.

“…The 2-pole configuration is of the conventional single-phase type and the parametric design study has been extended to include not only the capacitance but also the turns ratio (see Figs. [16][17][18][19]. For a set value of the starting capacitance, the turns ratio has a relatively reduced influence on the starting torque per amp value.…”

2005) Analysis and design of a two-speed single-phase induction motor with 2 and 18 pole special windings. IEEE Transactions on Energy Conversions 20(1):pp. 62-70.Abstract-The motor presented employs multiple independent windings for operation with two very different pole numbers. The 18-pole field is produced with a symmetrical three-phase winding connected in a Steinmetz arrangement to a single-phase supply. A unified analysis method has been developed and used to demonstrate the equivalence of a Steinmetz delta or star connection with a main and auxiliary winding of a single-phase motor. The method has been experimentally validated and also included are some specific motor design considerations.

“…Cycloconverters based static converters produced balanced output voltages but suffer from high low order harmonics [7]. Another initiative suggests having two capacitor converters for more balanced operation of induction motor using single-phase supply [8] which are tedious and unreliable. However, all these drawbacks can be overcome by incorporating advance programming techniques based on space vector PWM.…”

Three-phase system has numerous advantages over the single-phase system in terms of instantaneous power, stability, and cost. Three-phase systems are not available in every location particularly in remote rural areas, hill stations, low voltage distribution homes, and so forth. Having a system that is capable of converting directly the readily available single-phase system to three phases will have greater usability in various applications. The routine techniques adopted in the direct ac-ac single-phase-to-three-phase converters do not yield the best desired outputs because of their complexity in the segregation process and bidirectional nature of the input signal. Other initiatives use ac-dc-ac converters which are huge and costly due to dc link energy storage devices. Further, none of these systems provide a convincing result in producing the standard three-phase output voltages that are 120° away from each other. This paper proposes an effective direct ac-ac single-phase-to-three-phase conversion technique based on space vector pulse width modulation based matrix converter system that produces a convincing three-phase output signals from a single-phase source with balanced modulation index characteristics. The details of the scientific programming adopted on the proposed technique were presented.
