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. Method of 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 the steps of:

providing a plurality of individual separate cables on a vehicle and moving the vehicle on said carrier;

withdrawing the cables individually as the vehicle moves along the carrier and bending the cables individually commensurate with a desired meandering configuration for each of the cables as becoming thereby a part of a winding package to be placed into said grooves;

providing on said vehicle a plurality of holders which holders are being paid in steps and being spaced from each other commensurate with the spacing of the grooves;

placing the meander shaped cables in superimposed staggered relationship corresponding to the winding pattern to be attained and providing ribbon connection as well as placing the holding elements at a fixed distance onto portions of the cables which extend transversely to the extension and direction of extension of the stator as a whole to thereby complete a winding package; and

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

2. Method as in claim 1 and including attaching a grounding strip in contact with all of said cables along the extension and on each of said transverse portions.

3. Method as in claim 1 providing for a loop portion of said winding package.

4. Method as in claim 1 including providing for a running of assembled cables from the vehicle above the carrier to a position below said carrier and providing further for pushing the transverse portion up into the grooves.

5. Method of 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 the steps of:

providing on a vehicle a plurality of separate cables as well as plural fastening elements;

running said vehicle on said carrier plate while paying said cables;

assembling on the vehicle, in situ and on a step by step basis from the cables, a three phase winding package with ladderlike rungs;

providing the windings of the package with holders; and

mounting the winding package to the stator by placing the rungs with holders into the grooves as the vehicle runs along the carrier plate.

6. Method as in claim 5 including providing for a running of assembled cables from the vehicle above the carrier to a position below said carrier and providing further for pushing the rung portion up into the grooves.
