    Abstract: A position measuring apparatus detects, from respective first and second imaging planes of first and second captured images, first and second corresponding points estimated to represent a common three-dimensional position. The apparatus calculates first to fourth projected points. Each of the first and second projected points represents a projected point of the first corresponding point on a corresponding one of the first and second common planes. Each of the third and fourth projected points represents a projected point of the second corresponding point on a corresponding one of the first and second common planes. The apparatus calculates a first beam connecting the first and second projected points, a second beam connecting the third and fourth projected points, and a point having a minimum square distance relative to each of the first and second beams as a restored point representing the three-dimensional position of the first and second corresponding points.

    Abstract: An electric motor includes a rotor and a stator including a stator core, a plurality of armature windings, a plurality of field windings, and a plurality of bonded magnets. The stator core has a plurality of teeth alternately defining field slots and armature slots along a circumferential direction, and a stator yoke magnetically coupling the plurality of teeth opposite the rotor. Each armature winding is wound around two of the teeth sandwiched between an adjacent pair of the armature slots. Each field winding is wound around two of the teeth sandwiched between an adjacent pair of the field slots. The magnets are individually located in the field slots while opposing the field windings in the radial direction. Each adjacent pair of the magnets along the circumferential direction respectively has an adjacent pair of pole surfaces, with the adjacent pair of pole surfaces having a same polarity.
