Abstract
A variable speed accelerator includes an electric driving device and a transmission device. The electric driving device includes a constant-speed motor rotating a constant-speed input shaft of the transmission device in a first direction, and a variable-speed motor having a variable-speed rotor connected to a variable-speed input shaft of the transmission device and rotating an output shaft of the transmission device at a maximum rotation rate by rotating the variable-speed rotor at a maximum rotation rate in a second direction. The accelerator includes a power source line connecting the variable-speed motor with a power source so that the variable-speed motor rotates in the second direction, a rotation rate controller, and a bypass line connecting the variable-speed motor with the power source so that the variable-speed motor rotates in the first direction.
