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.
