Title:
STARTING METHOD FOR VARIABLE SPEED ACCELERATOR AND STARTING CONTROL DEVICE FOR VARIABLE SPEED ACCELERATOR
Document Type and Number:
WIPO Patent Application WO/2017/037934
Kind Code:
A1
Abstract:
This starting method is for a variable speed accelerator provided with an electric device that generates rotational drive force and a transmission device that changes the speed of the rotational drive force generated by the electric device and transmits the result to an object to be driven. The transmission device is a planetary gear transmission device. The electric device comprises: a constant speed electric motor having a constant speed rotor that causes the internal gear carrier shaft of the transmission device to rotate in a first direction; and a variable speed electric motor that comprises a variable speed rotor connected to the planetary gear carrier shaft of the transmission device, that functions as a generator in a generator mode in which the planetary gear carrier shaft is rotated in a first direction, and that functions as an electric motor in an electric motor mode in which the planetary gear carrier shaft is rotated in a second direction that is the opposite direction from the first direction. The starting method for a variable speed accelerator includes: a constant speed electric motor start-up step in which the constant speed electric motor is started up and the rotational speeds of the constant speed rotor and the internal gears are made to gradually increase in the first direction; and a generator mode operation step in which the variable speed electric motor is operated in the generator mode and the planetary gear carrier is rotated in the first direction.
