Title:
VARIABLE SPEED ACCELERATOR AND METHOD FOR STARTING VARIABLE SPEED ACCELERATOR
Document Type and Number:
WIPO Patent Application WO/2017/217483
Kind Code:
A1
Abstract:
A variable speed accelerator, wherein an electric drive device has a constant speed motor having a constant speed rotor for rotating the constant speed input shaft of a planetary gear transmission in a second direction, and also has a variable speed motor which has a variable speed rotor connected to the variable speed input shaft of the planetary gear transmission, rotates the output shaft at maximum rotation speed by rotating the variable speed rotor at maximum rotation speed in a first direction, and functions as a generator while in generator mode and functions as a motor while in motor mode. The variable speed accelerator is further equipped with a clutch for transmitting the drive force from the variable speed rotor to the constant speed rotor, when the rotation speed of the variable speed rotor in the second direction is greater than the rotation speed of the constant speed rotor in the second direction.
