  • Device for producing coil windings in stator laminated cores
    Patent number: 6401326
    Abstract: A device for mounting stator coils (7, 8) in stator laminated cores (6) is proposed which permits fabrication with an increased degree of automation. This is achieved according to the invention by virtue of the fact that a movable hoisting unit (1) is provided with a frame (2) and a holder (3), which can be moved relative to the frame (2), for a stator laminated core (6), the hoisting unit (1) comprising at least one processing tool (10, 12) which can be moved relative to the frame (2) and/or the holder (3).

  • Apparatus for the winding of coils
    Patent number: 6283169
    Abstract: An apparatus (1) for the winding of coils or coil groups is proposed, in which apparatus (1) winding may be carried out with different wires (5, 19) at little cost. This is achieved according to the invention in that, in addition to a first so-called flyer (2) having a corresponding wire guide (4), a second flyer (15) and a second wire guide (17) separate from the first wire guide (4) are provided.

  • Method for inserting windings into stator slots
    Patent number: 4741093
    Abstract: A method and apparatus for placing prewound windings into the grooves of stator coils and armatures in which needles are employed to insert the stator coils into the grooves. During insertion, the needles are displaced with a feeding movement in a longitudinal direction to the slots thereby obviating damage to the wires during their insertion. During insertion both the needles with the inserted coils and cover slide are enabled to move to promote the insertion procedure and without causing damage to the coils in the process of such insertion.
