The winding inductance is an important parameter to analyze the characters of the slotless PM motor. In this paper an analytical energy method is introduced. By the method, the conductor inductance in the slotless motor can be figured out. Furthermore, an analysis method of the end winding inductance is presented in this paper. The calculation results are identical with the results of FEM and the actual measured value. It proves the calculation method of winding inductance in slotless motor is valid.

Analysis of a Permanent-Magnet Brushless DC Motor with Fixed DimensionsThe purpose of this paper is to describe the analysis of a permanent-magnet brushless DC motor with fixed outer diameter and active zone length. The influence of air gap, material of permanent magnets and their size on the magnetic flux density of the machine and magnetic flux is analyzed. The work presents the calculations of two programs, the comparison of the results and the most suitable combination of factors that has been found.
