Title:
TRANSFER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/172657
Kind Code:
A1
Abstract:
In this transfer system, a subject to be transferred can be accurately transferred by performing highly accurate alignment using: a linear induction motor, which is provided with a stator (4) that is provided with a plurality of primary-side coils (3) disposed along a transfer path (2), and a mover (5) that is movably provided along the transfer path (2); first inverters (6), which are provided corresponding to the primary-side coils (3) disposed in regions where aligning is necessary, said regions being on the transfer path (2), and which perform vector control with sensors; second inverters (7), which are provided corresponding to the primary-side coils (3) disposed in regions where aligning is not necessary, said regions being on the transfer path (2), and which perform V/F control; and a controller (8), which controls power supply to the primary-side coils (3) by outputting speed instructions to the first inverters (6) and the second inverters (7), and performs positional control by outputting, to the first inverters (6), speed instructions based on feedback position inputted from a detector (11).
