Abstract: The present invention relates to a rotary machine. Main technical problem is in that two rotating forces being different in the rotating direction are taken to the outside using one motor. Consequently, in the invention, a stator (3) is rotatably supported by a support body (2) and provided with an output shaft or an input shaft (34), and further static side and rotating side are electrically connected. The rotary machine according to the invention can be applied as the drive source of a load requiring the rotating force in different rotating direction, or can be applied as a generator by the power source of wide range and other wide use ranges.
