Claim:
1. An electric machine, comprising: a first carrier having electromagnetic elements; a second carrier having electromagnetic elements defining magnetic poles, the second carrier being arranged to move relative to the first carrier an airgap between the first carrier and the second carrier; the electromagnetic elements of the first carrier including a plurality of electric conductor layers, the electric conductor layers being formed of anodized aluminum conductors having corner gaps, the corner gaps being coated with a coating; the electromagnetic elements of the first carrier include posts, with slots between the posts, one or more of the electric conductor layers arranged through each slot, the posts of the first carrier having a post height in mm; the first carrier and the second carrier together define a size of the electric machine; the magnetic poles have a pole pitch S in mm; and the size of the electric machine, pole pitch and post height are selected to fall within a region in a space defined by size, pole pitch and post height, the region being defined by either 1) a first union of: the first set of inequalities and the second set of inequalities being respectively sets of inequalities A and B, or B and C, or C and D, in which the set of inequalities A is for a size of 25 mm, the set of inequalities B is for a size of 50 mm, the set of inequalities C is for a size of 100 mm, the set of inequalities D is for a size of 200 mm; or 2) a second union of a surface as defined by set of inequalities D and a corresponding set of all points with size greater than the surface but with pole pitch and post height corresponding to points within the surface; where A is selected from the group of sets of inequalities consisting of: B is selected from the group of sets of inequalities consisting of: C is selected from the group of sets of inequalities consisting of: and D is selected from the group of sets of inequalities consisting of:
