In this article, a novel five-phase fractional-slot concentrated winding (FSCW) with 20-slot/22-pole is presented. It benefits not only the advantages of conventional FSCW but also weak space harmonics magnetomotive force (MMF). The allows eliminating first sub-order harmonic. new layout topology obtained by combination stator shift technique in slots special coupling windings (star-pentagon), ...
A novel approach of shape optimization to reduce pulsating torque components in spoke type permanent magnet motors is developed in this paper. This method is demonstrated on the iron pole shape optimization of an 8-pole/18-slot spoke type motor. The results of experiments show the effectiveness of the presented method.
Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
This paper presents a detailed analysis and design guidelines for advanced nonoverlapping winding induction machines (AIMs) with coil-pitch of two slot-pitches by considering some vital empirical rules flux-weakening characteristics. The aim the study is to develop type new stator topology (IMs) that will lead decrease in total axial length without sacrificing torque, power, efficiency. key per...
the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
While electrical machine designers typically go to great lengths choose the optimal number of stator slots based on electromagnetic performance, often thermal aspects this selection are overlooked. This article investigates multi-domain impacts related slot selection, combining both and aspects. Taking an existing 42-kW 4-pole, 12-slot with Halbach-array surface-PM rotor, used within a more-ele...
abstract this research has been carried out with the purpose of investigating the conditions and related elements of the employment of the educational sciences graduates of hamedan province universities in 1382-1387 academic years. it has been a descriptive research of a correlation kind, and the population number has been 1180 grduates of payam- e noor universites in asad – abaad, kaboudaraha...
Surface mounted permanent magnet Vernier (SPM-V) machines, because of their high torque density and multi-pole structure, are promising candidates for low-speed direct-drive applications. To achieve density, the SPM-V machines generally designed with gear ratios. Therefore, operating frequencies can be much higher than those conventional SPM machines. This potentially increases alternating curr...
