Abstrakty
W pracy przedstawiono metodę projektowania i analizy przepływu uzwojeń ułamkowych 2-fazowych. Wobec trudności jakie przedstawia zaprojektowanie uzwojeń o 2,4,8,... parach biegunów pokazano oryginalną metodę projektowania takich uzwojeń niesymetrycznych. lecz o znikomym stopniu niesymetrii kątowej i dobrych pozostałych właściwościach elektromagnetycznych.
The paper presents the method of design and analysis of 2-phase fractional-slot windings (FSW) for AC machines. The 2-phase induction motors find their applications in the servosystem drives but also in converter compact drives, in which 2 axes converter systems are less expensive and better to control. In the paragraph 2 of the paper the algorithmic method of FSW design [8,10] is described with regard to the 2-phase symmetrical windings (7). The chapter 3 is devoted to asymmetrical 2-phase windings. At first the review of the possible symmetrical solutions is presented. It is clear that for some of pole-pairs, such as p=4,6,8... it is difficult to obtain symmetrical integral windings as well as the fractional ones. So the new concept of the asymmetrical fractional-slot windings is proposed (9), which will cause only the minor angular asymmetry - especially in the case that the given rule (10) is observed. In the paragraph 4 two examples of FSW design for the 2-phase motors are presented. The first one is for the Q(s)Ip=36/5 motor which requires quite symmetrical FSW winding and the second one concerning Q(s)Ip= 36/4 motor. The latter is one of the difficult cases with practically one possibility of Q(s) choice if integral windings are considered and no symmetrical solution for the FSW. In this case the new method is demonstrated and the design and analysis of the slightly asymmetrical FSW are presented. The harmonic analysis of the MMFs (Table 2) for this winding confirms its good quality.
