Embodiment Construction

[0016] see figure 1 , figure 1 It is a partial structural schematic diagram of a preferred embodiment of the off-line test device for electromagnetic performance of a long stator linear motor of the present invention. The device includes the measured length stator as the stator part, and adopts the mover steel plate 9 to simulate the mover part. The long stator 1 is fixed on the test device platform 4 by fastening bolts 2; the three-phase winding 10 is arranged in the tooth slot of the long stator, and the number of turns and the access current of the three-phase winding 10 are determined by the ampere-turns of the winding required by the test. The sub-steel plate 9 is connected to the guide rail 3 on the test platform 4 through the bracket 5 , and the movable sub-steel plate 9 and its bracket 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 sets of induction coils 8 arranged at different posit...

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, in particular to an off-line testing device for the electromagnetic performance of a long stator linear motor. Background technique: [0002] The long stator linear motor is the main load-carrying and driving component of the track system of the high-speed maglev train, which provides the levitation force and driving force for the maglev train. At present, for general rotary motors, the inspection index is to test its torque, and for linear motors, it is to measure thrust. After the long stator of the high-speed magnetic levitation track is manufactured, how to judge its electromagnetic performance before installation is obviously a very important task. However, there is no offline test for the electromagnetic performance of the magnetic levitation long stator linear motor at home and abroad. related technical reports. Invention content: [0003] The technical problem to be solved ...
