Choice of pole number and slot number has dominant effect on machine performance. In this paper an extensive investigation of axial-flux PM BLDC machines having different pole and slot combination has been carried out.
Durham Research Online Slot pole combinations such as 9-slots 8-poles or 9-slots 10-poles, maximise the fundamental winding factor of the machine, comparable to that of a distributed winding machine. If the limitations and consequences of applying FSCW are understood, suitable combinations with higher pole numbers could be found, ... Design and Analysis of a Fractional-Slot Concentrated ...

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].

# of poles and # of slots, what does it mean? I fly EDF and use only inrunners. What is the difference between say a 4 pole 12 slot Neu motor and a 6 pole 18 slot Tenshock motor or for that matter 6 pole 9 slot Tenshock all of the same or very similar Kv?
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

Effect of Slot and Pole Combination on the Leakage
This paper presents a mathematical investigation of the influence of the slot/pole number combination on the iron loss of permanent magnet (PM) motors. A simplified electromagnetic model of PM motors was used to develop a mathematical method of evaluating iron loss for any combination of slots and ...
