ALTERNATING-CURRENT MOTOR

摘要

A stator core (3) is equipped with a plurality of slots (12). Multiple stator coils (4) are each formed into a coil having a rectangular cross section. The stator coils (4) are inserted into the slots (12) in a double-layer winding system such that a lower coil (4b) is inserted on an interior side of one of the plurality of slots (12) and an upper coil (4a) is inserted on an entry side of another slot (12) of the plurality of slots (12). Each of the slots (12) is provided with a space that enables the lower coil (4b) to be rotated on the interior side of the slot (12) when the upper coil (4a) is lifted up from the other slot (12).
