METHOD FOR INSERTING A COIL IN A POLYPHASE ROTATING ELECTRICAL MACHINE STATOR, AND ASSOCIATED STATOR

摘要

The invention concerns a method for inserting a corrugated coil in an alternator stator, the coil comprising a number of wires (60), each designed to form around the inner surface of an assembly of plates a spiral including a number of turns (73) corresponding each to one turn of the inner surface. The method includes forming each wire (60), the latter being configured into a succession of recesses (71) comprising two lateral branches (711) designed to be inserted each into a slot (30); and inserting the turns (73) of each wire into a series of slots (30) of the stator, the turns of the various wires (60) being radially superimposed in a predetermined sequence. The invention is characterized in that the wires (60) are inserted in the slots (30) simultaneously, the turns (73) of the various wires (60) alternating in the predetermined stacking sequence.
