Influence of the Coil Pitch and the Slot/Pole Number ... 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 ...

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, ... CiteSeerX — Investigation on pole-slot combinations for 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.
Vernier Motor with Fractional-Slot Concentrated Winding ... slots (or called the flux modulation pole), and winding pole pairs, respectively [1–4]. This rule can be readily applied to the distributed-winding machines, however, these windings generally employ lengthy end-turns with higher copper losses, and thus fractional-slot concentrated windings (FSCW) are preferred [5]. Influence of design parameters on cogging torque in permanent ... the “goodness” of slot and pole number combinations from the point of view of cogging torque, where: (3) Although there is no formal basis for relating to the am-plitude of the cogging torque, it has been found that the larger the factor the larger will be the cogging torque. In order to demonstrate the influence of the slot and pole Design of Permanent Magnet Machines for Field-Weakening Operation investigation of the effect of stator-slot and rotor-pole number combinations for surface- mounted PM (SPM) machines, and the stator-slot and rotor-effective-slot number combinations for interior permanent magnet (IPM) machines.
