“…The software used for this purpose is called finite element method magnetics (FEMM) (Meeker, 2010). In order to be able to analyse the two models of the SPBLDC motor accurately, a calculation of the magnetic field has to be performed for the two motor topologies (Iepure et al, 2008;Lefley et al, 2010). The 2D analysis is very suitable for this type of geometry and has a lot of advantages over the 3D calculation, such as lower memory storage and reduced computation time.…”

Purpose -The purpose of this paper is to perform an optimal design of single phase permanent magnet brushless DC motor (SPBLDCM) using efficiency of the motor as objective function. In the design procedure performed on SPBLDCM, particle swarm optimisation (PSO) as an optimisation tool is used. Design/methodology/approach -The created computer programme for optimal design of electrical machines is based on the PSO. According to the design characteristics of SPBLDCM, some of the motor parameters are chosen to be constant and others variable. A comparative analysis of both motor models based on the value of the objective function, as well as the values of the optimisation parameters, is performed. Findings -From the comparative data analysis of both motor models, it can be concluded that the main objective of the optimisation is realised, and it is achieved by an improvement of the efficiency of the motor. Originality/value -An optimisation technique based on PSO has been developed and applied to the design of SPBLDCM. According to the results it can be concluded that the PSO is a very suitable tool for design optimisation of SPBLDCM and electromagnetic devices in general. The quality of the PSO model has been proved through the data analysis of the prototype and optimised solution. At the end, the quality of the PSO solution has been again proved by comparative analysis of the two motor models using FEM as a performance analysis tool.

The cogging torque is undesirable effect in the brushless dc (BLDC) motor, causing vibration and audible noises. It arises from the rotor permanent magnet interacting with the steel teeth on the stator. This paper studies the various reduction methods of cogging torque when designing a BLDC motor. These methods can be categorized according to three parts of motor structure, i.e., air gap length, rotor and stator parts. The finite element method magnetic (FEMM) is primarily used to analyze the cogging torque among these different reduction methods. In this paper, a 4-pole, 24-slot BLDC motor is focused with variations of air gap length, rotor, and stator parts in order to study its cogging torque reductions. Finally, the FEMM simulation results are presented to validate these reduction methods.

In order to equip the single‐phase brushless permanent magnet (PM) motor with self‐starting capability without a complex structure, we present a new kind of asymmetric air‐gap topology which can lead to the d‐, q‐axis magnetic circuit asymmetry of the motor. The field‐circuit‐coupling finite element method simulation model of the proposed motor controlled with a constant V/f control is built by using the 2D Maxwell software. The geometric parameters of the motor are also optimized by changing pole arc ratio of the PM (αp) and its eccentricity (e), and the operational characteristic is investigated. Finally, an experimental platform of the prototype and its control system are set up. Performance comparison of the experimental results and simulation results of the proposed motor running in various operating modes is reported. All the results show that the asymmetric air‐gap single‐phase brushless PM motor has potential to be used in the household appliances. © 2017 Institute of Electrical Engineers of Japan.
