PROBLEM TO BE SOLVED: To provide a connection pattern switch device suitable for improving the versatility of a motor by changing the characteristic of the motor. SOLUTION: A switch is installed, the switch changes over the connection patterns of coils LA1-LA6 between six poles A1-A6 so that the reactance of an armature wire becomes variable, changes over the connection patterns of coils LB1-LB6 between six poles B1-B6 80 that the reactance of an armature wire 12b becomes variable, and changes over the connection patterns of coils LC1-LC6 between six coils C1-C6 so that the reactance of an armature wire 12c becomes variable. |
