POWER TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power transmission device having a reduced size while increasing the driving force of a load without increasing the capacity of a stator conductor and the capacity of a power converting device which supplies power to the stator conductor.

SOLUTION: A stator which uses power transmitted to a first rotor 28 for generating power in a first stator winding 30 and a stator which uses power supplied to a second stator winding 20 for generating power in a second rotor 18 are shared with each other in one stator 16. In the stator 16, the second stator winding 20 is arranged outside the first stator winding 30 in the radial direction. The first rotor 28 is arranged inside the stator 16 in the radial direction in opposition to the stator 16, and the second rotor 18 is arranged outside the stator 16 in the radial direction in opposition to the stator 16.
