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, ...
