Abstract:
A variable speed accelerator is provided, including an electric driving device which generates a rotational driving force, and a planetary gear transmission device which changes the speed of the rotational driving force generated by the electric driving device and transmits the changed rotation driving force to a driving target, wherein a sun gear shaft forms an output shaft connected to the driving target, an internal gear carrier shaft forms a constant-speed input shaft, and a planetary gear carrier shaft forms a variable-speed input shaft, the electric driving device includes a variable-speed motor having a variable-speed rotor connected to a variable-speed input shaft of the transmission device, and a constant-speed motor having a constant-speed rotor connected to a constant-speed input shaft of the transmission device, the variable-speed rotor and the planetary gear carrier shaft are formed in a cylindrical shape centered on the axis and have a shaft insertion hole formed to pass therethrough in the axial direction, the constant-speed rotor is inserted through the shaft insertion hole, and the variable speed accelerator further includes a rotation rate sensor which measures a rotation rate of the transmitting gear, and a control device which performs vector control of the variable-speed motor based on the rotation rate measured by the rotation rate sensor.

Claim (Index 1):
