Abstract

A method of making a multiphase winding package and placing it into the grooves of a linear stator being mounted, with open grooves facing down, on the underside of a support and carrier plate, includes storing and paying individual ones of a plurality of separate cables on a vehicle while moving the vehicle on the carrier; the cables are bent individually commensurate with a desired meander configuration for each of them in a winding package; the meander shaped cables are then superimposed corresponding to the winding pattern to be attained; ribbon connection as well as holding elements are provided at fixed distances onto runglike portions of the cables; the thus, in situ assembled winding package is mounted to the stator by placing these runglike portions with holders into the grooves of the stator.

Claims

1. Apparatus for providing a multiphase winding into the grooves of a stator of a linear motor, the stator being mounted with open grooves facing down, on the underside of a support and carrier plate being carried in an elevated position, comprising in combination,

a plurality of individually reelable stores provided for individual payout of cable from respective ones of said stores;

means for meander shaping the individual cables;

a conveyor belt means provided on the vehicles for moving individual and spaced apart holding elements towards a particular area;

mains in said particular area of the vehicle for placing the holding elements as provided by the conveyor belt onto portions of the meandering cables as arriving in the particular area;

means on the vehicle for connecting said holding elements together thereby forming a winding package; and

an outrigger boom for receiving said winding package as assembled and placing it within reach of a tool by means of which the portions of the cable holding said holding elements are forced into stator grooves.

2. Apparatus as in claim 1 and including on the vehicle means for running assembled cable from the vehicle above the carrier to a position below said carrier;

and means for pushing transverse portions of the cables into said grooves.

3. Apparatus for providing a multiphase winding into the grooves of a stator of a linear motor, the stator being mounted with open grooves facing down on the underside of a support and carrier plate and being carried in an elevated position, comprising:

a vehicle including a plurality of stores for separate cable as well as for storing plural fastening elements;

means for causing said vehicle to run on said carrier plate while paying individual cables from respective ones of said stores;

assemblying means on the vehicle for assemblying in situ and on a step by step basis a three phase winding package from said cables, the package having ladderlike runs;

means on the vehicle for providing the windings of the package with holders; and

means on the vehicle for mounting the winding package to the stator by placing the package with holders attached into the grooves as the vehicle runs along the carrier plate.

4. Apparatus as in claim 3 including means for running the assembled three phase winding package from the vehicle above the carrier to a position below the carrier and further means for pushing the rung portion into the grooves.

5. Apparatus for providing multiphase winding into grooves of a stator of a linear motor, the stator being mounted with open grooves facing down on the underside of a support and carrier plate being carried and supported in elevated position a vehicle comprising:

means on the vehicle providing a plurality of individual separate cables;

means for moving the vehicle on said carrier while withdrawing the cables individually as the vehicle moves along the carrier;

means for bending the cable individually commensurately with the desired meandering configuration for each cable as becoming thereby a part of a winding package having transverse rung-like portions to be placed into said grooves;

means on the vehicle for providing a plurality of holders onto the rung-like portion of the package, the holders being paid in steps and being spaced from each other commensurate with the spacing of the grooves;

means for placing the meander shape cables in superimposed staggering relationship corresponding to the winding pattern to be attained;

means for providing ribbon connection for interconnecting the cables as well a for placing the holding elements at a fixed distance into portions of the cable which extend transversely to the extension and direction of extension of the stator as a whole to thereby complete the winding package; and

means for placing said portions with attached holding elements into said grooves, in sequence and pursuant to the propagation of the vehicle on the carrier.
