Abstract
A sequentially joined segment armature coil is provided which may be employed in an ac machine such as an ac motor or motor generator. The armature coil is equipped with three phase coils each of which is made up of a first and a second phase windings identical in number of turns. This structure permits the number of turns of the armature coil to be changed easily by changing a connection of the first and second phase winding between a series connection and a parallel connection or changing a connection of the phase coils between a star connection and a delta connection. The structure also enables terminal leads of the first and second phase windings of each of the phase coils to be collected and withdrawn outside the ac machine, thus facilitating ease of arrangement of the terminal leads.
