Abstract :
A method which uses finite-element techniques for designing linear tubular brushless DC machines is described. The design technique makes use of approximate calculations to decide the machine dimensions. Finite-element analysis is then employed to calculate a series of designs and determine the optimum one. The effects of variation in slot depth and pole pitch are illustrated. The finite-element analysis is supported by analytical results from using a simple method of calculating electromagnetic force
