Computer Aided Design and FE Analysis of a PM BLDG Hub Motor

This paper presents the computer aided design (CAD) of a PM BLDC hub motor. Using the developed CAD program, a 30 W, 48 V, 310 rpm PM BLDC hub motor meant for a ceiling fan application is designed. The design variables such as flux density in air gap and iron, slot space factor, stack length of the motor, air gap length, number of magnet poles, etc., are assumed. Basic output equation is used for the design algorithm. Output of the developed CAD program gives the design data and the same is validated by FE analysis. This paper also presents the parametric analysis of the designed PM BLDC hub motor and the results of parametric analysis are submitted.
