Abstract:
1. A method for manufacturing a stator, the stator comprising: a stator core and a plurality of coils, wherein the stator core includes a plurality of split core pieces each having a tooth portion, the split core pieces being annularly arranged such that distal ends of the tooth portions face radially inward, wherein the coils are each wound about one of the tooth portions, the coils are divided into groups of n phases, the method comprising: winding a lead wire about each adjacent pair of the tooth portions with the tooth portions are spread such that the distal ends of the tooth portions are separated from on another, such that coils of different phases are provided on each adjacent pair of the tooth portions, wherein a connecting wire connects the coils of the different phases; making the spread stator core have an annular shape such that the distal ends of the tooth portions face radially inward; and connecting the connecting wires, each of which connects coils of different phases wound about circumferentially adjacent tooth portions, to each other.
