Abstract
Disclosed is the apparatus and method for depositing a winding of varying depth along the teeth of a stator. The necessity for complex motion of the winding head is avoided by moving the head in conventional reciprocating fashion and then introducing winding turn distributing elements from outboard of the stator. The distributing elements are moved radially inward between the path of the wire-dispensing component of the winding head and the end faces of the stator tooth receiving the winding. The distributing elements are moved in a series of reciprocating strokes of decreasing length as the winding head moves through its winding path, thereby distributing the windings in increasing depth toward the base of the stator tooth receiving the winding.
Claims11
A stator winding apparatus for placing a winding of varying depth along the length of radially inwardly extending teeth or pole cores of a stator, the stator having a cylindrical configuration with radial teeth extending inwardly to define a central bore, said apparatus comprising a winding head actuated through said central bore and having a wire-dispensing member moved in a path sequentially parallel to and transverse to the axis of the stator bore and encircling the base of the stator tooth receiving the winding, winding turn distributing elements movably supported outboard of the stator adjacent the end faces thereof, said distributing elements being movable radially inward between said path of the wire-dispensing member and the stator tooth receiving the winding, and means for moving said distributing elements radially inward with respect to the stator in a series of reciprocating strokes of decreasing length as said head moves through its winding path to thereby distribute the windings in increasing depth toward the base of the tooth receiving the winding.
A core winding apparatus for placing a winding of varying depth along the length of radially inwardly extending teeth of a cylindrical core, the core having a hollow cylindrical configuration with radial teeth extending inwardly to define a central bore, said apparatus comprising a winding head actuated through said central bore and having a wire-dispensing member moved in a path sequentially parallel to and transverse to the axis of the central bore and encircling the base of the core tooth receiving the winding, winding turn distributing elements movably supported outboard of the core and adjacent the end faces thereof, said distributing elements being movable radially inward between said path of the wire-dispensing member and the core tooth receiving the winding, and means for moving said distributing elements radially inward with respect to the core in a series of reciprocating strokes of decreasing length as said head moves through its winding path to thereby distribute the windings in increasing depth toward the base of the tooth receiving the winding.
The method of depositing windings of varying depth on a core which is cylindrical in configuration and has a plurality of teeth extending radially inward from the circumferential portion of the core to a central axial bore, said method comprising:
- providing a wire-dispensing member which extends through the central bore and radially parallel to the core teeth, moving said member in a reciprocating linear and angular winding path adjacent the base of a tooth of the core to deposit a multiple-turn winding transversely around the tooth of the core, providing elongated winding-turn distributing elements which are movably supported outboard of the core and extend radially inward between the core end faces and the path of motion of said wire-dispensing member, and, as said member is moving in its winding path, moving said distributing elements radially inward in a series of reciprocating strokes of decreasing length to distribute the windings in increasing depth toward the base of the tooth.
