摘要： An electric machine includes an exciter part and an induction part disposed adjacent the exciter part. The exciter part and the induction part define an air gap there-between and are movable relative to one another thereby defining a direction of movement. The induction part includes teeth disposed adjacent one another and projecting in a direction toward the air gap. The teeth define grooves therebetween, each of the teeth having a tooth base and a tooth tip adjacent the air gap. In addition, each of a plurality of the teeth further includes a middle portion having two ends and a constant width defined in a direction along the air gap and perpendicular to the direction of movement; and a pair of tooth widening portions, each of the tooth widening portions having a free end and a transition end and being located at one of the two ends of the middle portion at the transition end thereof for forming one of the plurality of the teeth with the middle portion. Each of the tooth widening portions further has a dimension defined in the direction of movement which decreases from a corresponding end of the middle portion toward the free end, and a width defined in the direction along the air gap and perpendicular to the direction of movement which decreases from a corresponding tooth base toward a corresponding tooth tip.

摘要： An electric machine (2) comprising a first functional part (4) with a permanently magnetic excitation system (12) and a second functional part (6) with a conductor system (10), the first functional part (4) and the second functional part (6) being movable relative to each other along the active area (24) of an air gap. The first functional part (4) comprises--as seen progressively in the direction of relative movement (32)--an alternating sequence of permanent magnets (12) magnetized in the direction of relative movement (32), and of magnetically conductive material portions (14). The magnetically conductive material portions (14) each have--facing the active area (24)--a magnetic flux outlet area (22) which is smaller than the sum of the magnetic flux cross-sectional areas (21) of the two adjacent permanent magnets (12), so that the magnetic flux of the permanent magnets (12) is concentrated for the active area (24). The width of the permanent magnets (12), measured in the direction of relative movement (32), increases as their distance from the active area (24) increases, while the width of the magnetically conductive portions (14) decreases.
