Axial-Flux PM BLDC Machines with Concentrated Windings ... between PMs and stator teeth. Beside pole and slot combination, pole arc has significant effect on cogging torque. In this research cogging torque of three machines are set at their minimum for different configuration. The optimum ratios of pole arc to pole pitch for minimizing cogging torque for a given slot and pole number is [18-21]: Investigation on Pole-Slot Combinations for Permanent ... Investigation on Pole-Slot Combinations for Permanent-Magnet Machines with Concentrated Windings Article (PDF Available) · January 2004 with 3,362 Reads Cite this publication Investigation of slot-pole combinations on IPM BLDC motor ... In order to meet these requirements, it is important to consider the slot-pole combinations in the initial design of a motor. Some studies have been conducted on the characteristics of the IPM BLDC motor according to the slot-pole combinations in various papers [4,5]. Download Limit Exceeded - CiteSeerX

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract- The aim of this paper is to find the best concentrated windings layouts for high pole number permanent-magnet (PM) machines. Pole and slot numbers are varied from 4 to 80 and 6 to 90 respectively. Among all the pole/slot combinations, those giving the highest winding factors are provided. Investigation on Slot/Pole Number Combinations for PMSM ... And selection of slot/pole number combinations is the key step for torque PMSM design. So this paper mainly studies on the slot/pole number combinations features of torque PMSM with concentrated winding. First, this paper deeply discussed five features of slot number-phase table of cell motor. And Investigation on Slot/Pole Number Combinations for PMSM ... Investigation on Slot/Pole Number Combinations for PMSM with Concentrated Fractional Slot Winding Based on Slot Number-Phase Table . ... Because Slot number-phase table is brought in, the method proposed by this paper is convenient to carry out automatic analysis and calculation by computer ... Slot/pole Number Combination, ...
literature is focused on high slot pole combination of FSPM machines [4] - [6] since low slot pole combinations were found to produce unbalanced flux linkages [7], [8]. In order to reduce the fundamental frequency, the number of rotor poles must be minimized. In this paper, research results that are geared toward the

mechanical stress, and so on. The determination of pole-slot (p-s) combinations on the basic design is very important to a traction motor to satisfy the required high-power density, the low torque ripple, and the cogging torque. To study the output characteristics of IPMSM according to pole-slot combinations, this paper introduces about 100-kw ...
