ABSTRACT:
A rotary electric machine the rated voltage of which is changeable by changing-over the connections of the connection terminals of its armature winding. The connection terminals are classified into those used as power input terminals which are connected directly to AC power supply terminals regardless of the change-over of the rated voltage, and those which are not directly connected to the AC power supply terminals and are selectively connected to one another depending on the desired rate voltage. The former connection terminals used as the power input terminals are connected to the power supply terminals by lead wires, and the latter connection terminals are selectively connected to each other by using jumper conductors. The jumper conductors are held by a jumper conductor holder in a relation electrically insulated from one another. A plurality of such jumper conductor holders are prepared, and a suitable one is selected to deal with the selected power supply voltage driving the rotary electric machine.
