摘要：
As the power supply of movable load such as linear induction motor (LIM), movable inductively coupled power transfer (MICPT) system is flexible, security, and environment friendly. A power supply scheme with MICPT for linear induction motor drive (LIMD) system is proposed. The equivalent characteristic of LIMD as the load of MICPT is analyzed. The output voltage characteristic of MICPT is studied when the current of the primary winding is kept constant, including the affection of contactless transformer mutual inductance and motor different operation modes. A variable resistance adopted to equivalent circuit of the LIMD as the load of MICPT is proposed. An experiment setup with LIMD system powered by MICPT is built. The LIM can move steadily along the rail with movable contactless power supply. Analyses, simulation and experimental verify the correctness and feasibility of the proposed scheme and equivalent model. ©, 2015, Chinese Machine Press. All right reserved.
