Claim:
1. A linear electric machine, comprising: a first carrier having an array of 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 posts, with slots between the posts, one or more electric conductors in each slot, the posts of the first carrier having a post height in mm; the first carrier and the second carrier together defining a size of the linear electric machine; the magnetic poles having a pole pitch S in mm; the size of the linear electric machine, pole pitch and post height being 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: Set A1: Set A2: Set A3: B is selected from the group of sets of inequalities consisting of: Set B1: Set B2: Set B3: C is selected from the group of sets of inequalities consisting of: Set C1: Set C2: Set C3: and D is selected from the group of sets of inequalities consisting of: Set D1: Set D2: Set D3:
