This paper presents a novel staggered-teeth cylindrical transverse-flux permanent-magnet linear machine (TFPMLM), which aims to improve the power factor and force density. Due to the compact structure and high performance requirement, thermal problems should be seriously considered. The three-dimensional (3-D) temperature field model is established. The determination of convection heat transfer coefficients is discussed. Equivalent thermal conductivities of stator core and winding are given to simplify the analysis. With the thermal effect of the adhesive coatings among permanent magnets (PMs) and mover yoke taken into account, the temperature field distribution and variation rules of the TFPMLM are obtained using the finite volume method (FVM). The influences of slot filling factor and air flow velocity on the temperature field distribution are analyzed. It is found that the hottest spot of the TFPMLM appears in the middle of the end winding; and there is no risk of demagnetization for PMs.

To achieve these goals, this work presents an efficient application-oriented robust design optimization method for permanent magnet (PM) motors. The method consists of two main contributions. The first one is the development of an overall optimization strategy including qualitative and quantitative analyses to provide possible options for an application. Multi-physics analysis, uncertainty analysis, production cost and optimization models need to be investigated. The second one proposes a multilevel optimization method for the high-dimensional robust design problem of each option. To illustrate the advantages of the proposed method, PM motors with soft magnetic composite cores are investigated for domestic applications. The design optimization is conducted in terms of three motor options and three batch production volumes for both conventional deterministic and robust approaches, and it consists of eighteen high-dimensional multi-physics optimization problems in total. Main optimization results are presented and discussed. Experimental and simulation results are presented to validate the effectiveness of the proposed models and methods.

“…The selection of modelling methods and design methodology structure are application specific and therefore difficult to generalise, as evidenced by the various approaches taken in the literature, [3], [4], [6]- [9]. However, a common approach links a relatively detailed electromagnetic Finite Element (FE) model with a coarse low computational cost Thermal Equivalent Circuit (TEC) model, [3], [4], [6], [8], [9].…”
