Title:
VARIABLE SPEED ACCELERATOR
Document Type and Number:
WIPO Patent Application WO/2017/145367
Kind Code:
A1
Abstract:
Provided is a variable speed accelerator that has a constant speed electric motor (51) that has a constant speed rotor (52) that makes a constant speed input shaft (Ac) of a transmission device (10) rotate in a first direction. The variable speed accelerator also has a variable speed electric motor (71): that has a variable speed rotor (72) that is connected to a variable speed input shaft (Av) of the transmission device (10), that is a cylinder that is centered on a shaft line, and that has the constant speed input shaft (Ac) inserted through a shaft insertion hole (74) that passes therethrough in the axial direction; and that, by making the variable speed rotor (72) rotate at a maximum rotational speed in a second direction that is opposite the first direction, makes an output shaft (Ao) rotate at a maximum rotational speed. The variable speed accelerator comprises: an alternating current power source line (110) that connects the variable speed electric motor (71) and an alternating current power source such that the variable speed electric motor (71) rotates in the second direction; a rotational speed control device (100) that is provided on the alternating current power source line (110) and that controls the rotational speed of the variable speed electric motor (71); a first switch (SW1) that is provided on the alternating current power source line (110); and a braking circuit (2) that is on the alternating current power source line (110) and that is connected between the variable speed electric motor (71) and the first switch (SW1)/the rotational speed control device (100).
