Abstract-The thermal characteristic of a new out-rotor fault-tolerant permanent-magnet (FTPM) motor is modeled and predicted in this paper. Flow characteristics and thermal characteristics of this FTPM motor are calculated by using computational fluid dynamics method. The key is that an equivalent model is developed to replace the real motor, offering the merits of simplified meshing progress and convenient thermal calculation. Furthermore, the effectiveness of the developed equivalent model has been verified by simulation and experiment. In addition, the temperature distribution of the entire motor is given by using equivalent models. The results can be provided to improve motor thermal performance.

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.

-This research deals with design of the maximum thrust density with considering winding temperature rise of single-sided PMLSM. The temperature rise of winding which caused to machine characteristics such as copper loss, iron loss and efficiency was analyzed by FEM. The maximum allowable current density was calculated within the allowable temperature. The effects of loss and efficiency according to temperature characteristic were confirmed.
