AbstractA motor field assembly and method for constructing a permanent magnet motor wherein the shell is formed of relatively thick flat sheet stock as two rectangular portions and an elongated connecting portion. The rectangular portions are rolled into semi-cylindrical shapes and the connecting portion is bent at two places so that the two rectangular portions are in opposed parallel relationship to form a unitary cylindrical motor housing shell with a pair of diametrically opposed seams, the connecting portion forming an end wall of the motor housing. Annular permanent magnet segments are provided and mounted to the interior of the shell in spaced equiangular relation with a central portion of each segment of a pair of diametrically opposed segments spanning a respective seam.
