The method of the lines of flow remains always a design method which could be applied by a very broad population of manufacturers for the design of the electric machines. It is an easy method to implement, founded on basic electromagnetism principles. Our article present in general a procedure of calculation of the reluctances of variable reluctance machines (6/4) starting from the use of the analyticalrelations which generate the electromagnetic principles of the machine. A new method based on the simple geometry and the trigonometrically one was used for the calculation of the reluctances of the lines which through the air-gap of the machine. The results of the design obtained by the flow lines method with the application of this new approach were checked by the finite elements method. Analyzes and the comparison of the margins of error remain acceptable.
