Embodiment Construction

[0017] See figure 1 , figure 1 It is a partial structural diagram of a preferred embodiment of the electromagnetic performance offline testing device of the long stator linear motor of the present invention. The device includes the measured length stator as the stator part, and the mover steel plate 9 is used to simulate the mover part. The long stator 1 is fixed on the test device platform 4 by the fastening bolts 2; the three-phase winding 10 is arranged in the slot of the long stator. The number of turns and the access current of the three-phase winding 10 are determined by the winding ampere-turns required for the test. The sub-steel plate 9 is connected to the guide rail 3 on the test platform 4 through a support 5, and the movable sub-steel plate 9 and its support 5 can slide along the guide rail 3. Through the high-precision tension sensor 7 arranged on the mover steel plate 9 and the seven groups of induction coils 8 arranged at different positions inside the steel plate, ...

Said off-line testing equipment also includes a rotor steel plate connected with the above-mentioned guideway by means of supporting frame, said rotor steel plate has several holes, every hole interior is equipped with a group of electrodynamic induction coils, every group container three electrodynamic induction coils, and every induction coil is series-connected with A.C. electric meter. The long-stator to be tested is fixed on the testing platform.

Description

Technical field: [0001] The invention relates to a high-speed magnetic levitation railway, and particularly relates to an offline test device for electromagnetic performance of a long-stator linear motor. Background technique: [0002] The long-stator linear motor is the main bearing and driving component of the high-speed maglev train rail system, which provides levitation and driving force for the maglev train. At present, for general rotating motors, the test index is to test the torque, while the linear motor is to test the thrust. After the long stator of the high-speed magnetic levitation rail is manufactured, how to judge its electromagnetic performance before use and installation is obviously a very important task. However, there is currently no offline test specifically for the electromagnetic performance of the magnetic levitation long stator linear motor at home and abroad. Related technical reports. Summary of the invention: [0003] The technical problem to be solve...
