Abstract
The invention relates to a travelling wave machine which includes a stator and a rotor, wherein at least one stator coil and/or one rotor coil is arranged in at least one groove of the stator or the rotor, respectively, and wherein the stator coil or the rotor coil, respectively, projects from the groove at both sides in a longitudinal direction under the formation of a coil head, characterized in that the cross section of the stator coil or of the rotor coil, respectively, in the area of the respective groove differs from the cross section of the stator coil or the rotor coil, respectively, in the area of the coil head.
Claims6
A polyphase travelling wave machine including a stator (10) and a rotor (12), wherein
- at least one stator coil (18) and/or one rotor coil is arranged in at least one groove (16) of the stator (10) or the rotor (12), respectively,
- the stator coil (18) or the rotor coil, respectively, projects from the groove (16) at both sides in a longitudinal direction under the formation of a coil head (20),
- the cross section of the stator coil (18) or the rotor coil, respectively, in the area of the respective groove (16) differs from the cross section of the stator coil (18) or the rotor coil, respectively, in the area of the coil head (20), characterised in that
- the ratio of the thickness of the stator coil (18) or the rotor coil, respectively, in the area of the groove (16) to the thickness of the stator coil (18) or the rotor coil, respectively, in the area of the coil head (20) corresponds to the product of the number of phases of the travelling wave machine and the number of holes in each coil.
