Abstract

A polyphase winding of ladder-like configuration for a linear motor is installed into a prearranged inductor assembly having a plurality of parallely arranged grooves, the inductor being attached to the underside of a T-shaped type carrier; a vehicle runs on that carrier carrying a drum for storing the winding (cable assembly), and there is a deflection system which runs the winding from the drum towards the underside of the carrier in near-tangential disposition whereby a tool resiliently mounted on an outrigger causes rungs of the ladder to be sequentially forced into the grooves of the inductor and, possibly, locked therein.

Claims

1. Method of applying and fastening a prefabricated polyphase cable-winding assembly into the grooves of an inductor pertaining to a stator for a linear motor arranged along the underside of an overhung carrier, and wherein said grooves are arranged in parallel to each other essentially transverse to the linear extension of the stator, and wherein the cable-winding assembly resembles a ladder and cable portions resemble the rungs of a ladder comprising the steps of:

providing the cable assembly on a drum, the drum being placed on a vehicle, the vehicle running on said carrier;

unreeling said cable assembly from the drum as the vehicle runs on said carrier;

deflecting said cable assembly as unreeled through outrigger means and providing it to run towards said underside of said carrier in near-tangential fashion; and

causing a tool to engage said cable-winding so as to force said near-tangentially running cable assembly progressively into said groove.

2. Method as in claim 1 and including the step of providing for linear active driving advance of said cable assembly as it is withdrawn from said drum.

3. Method as in claim 1 and including the step of driving said drum.

4. Method as in claim 1 and including the step of centering said tool in relation to a lateral edge of said carrier.

5. Method as in claim 1 and including the step of controlling the tension of withdrawing said cable-winding from said drum.

6. Method as in claim 5 and including the step of interposing a buffer loop in said winding.

7. Method as in claim 6 and including the step of changing the orientation of said winding at least once on its propagation path from the drum to said tool.

8. Method as in claim 1 and including resiliently mounting said tool as it applies said winding to said grooves.
