<p>This 4.5 slots per pole and phase stator winding (20) comprises three phase windings (22, 24, 26) and is formed in a first layer (28) and a second layer (30) disposed in each slot (181-1827) of a stator. Each phase winding (22, 24, 26) forms at least two phase belts (34) comprising several coils turns (36). Each coil turn (36) comprises a first connecting bar (42) belonging to the first layer (28) and a second connecting bar (44) belonging to the second layer (30). For at least two phase windings (22, 24, 26), some outermost connecting bars (420, 440) of a group (46, 47) of first or second connecting bars (42, 44) of at least one phase belt (32, 34) are disposed in slots (182, 1810) which are separated from the slots (184-187, 186-188) which accommodate at least two other connecting bars of the same group by one slot (183, 189), which accommodates an innermost (42l, 44l) connecting bar of another group of first or second connecting bars of another phase belt (32; 34) of another phase winding. A single first phase winding (22) comprises at least one phase belt (32, 34) for which, all the first (42) connecting bars are disposed in adjacent slots (1812-1816) and all the second (44) connecting bars are disposed in adjacent slots (1823-1827).</p> |
