1. An electrical apparatus for a transportation vehicle, comprising:
an electromagnetic motor, wherein the electromagnetic motor comprises:
a first rotation device; anda second rotation device co-axially disposed with the first rotation device for electromagnetically matching with each other, wherein the electromagnetic motor operates in one of a motor mode and a generator mode; anda hydraulic device controlling the second rotation device; anda gear box providing a hydraulic power to the electromagnetic motor by the hydraulic device, wherein in the motor mode, the electromagnetic motor receives a first electric power to generate a magnetic field in the second rotation device to induce a first rotation of the first rotation device, and the hydraulic device drives a second rotation of the second rotation device in a direction opposite to the first rotation; and wherein in the generator mode, the electromagnetic motor produces a second electrical power generated by the electromagnetic field caused by a third rotation of the first rotation device, and the hydraulic device drives a fourth rotation of the second rotation device in a direction opposite to the third rotation. |
