Technical Field

[0001] This application relates to the technical field of synchronous motor testing devices, and in particular to a permanent magnet synchronous motor testing device for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels and adopt new in-vehicle power devices), integrating advanced technologies in vehicle power control and drive, and forming vehicles with advanced technical principles, new technologies, and new structures. Among them, permanent magnet synchronous motors are one of the important components in new energy vehicles.

This not only consumes time but also is not conducive to improving the testing efficiency, and is rather inconvenient. Utility Model Content

[0020] The embodiment of the present application discloses a testing device for a permanent magnet synchronous motor of a new energy vehicle. Refer to Figures 1 - 3, a testing device for a permanent magnet synchronous motor of a new energy vehicle, comprising a main body plate 2. A support seat 10 is fixed on the top of the main body plate 2. A rotating roller 11 is rotatably connected to the support seat 10. A connection hole 12 is provided at the center of the rotating roller 11, and the output end of the permanent magnet synchronous motor body 1 is adapted to the connection hole 12. A U-shaped hole is formed in the support seat 10, and a threaded rod 5 passes through the U-shaped hole. A pair of support plates 4 are fixed on the main body plate 2, and a threaded rod 5 is driven and installed between the two support plates 4 by a driving motor 6. It further includes a limiting mechanism, and the limiting mechanism is installed on the threaded rod 5 through a screwing plate 13 in the limiting mechanism. The screwing plate 13 is threadedly connected with the threaded rod 5. The permanent magnet synchronous motor body 1 is installed and fixed on the limiting mechanism. A pair of slide rails 3 are fixed on the top of the main body plate 2.

[0021] In this embodiment, as Figure 1 and Figure 2 shown, the limiting mechanism further includes a moving seat 7 and limiting clamping pieces 9. The screwing plate 13 is fixed to the bottom of the moving seat 7. The moving seat 7 is fixedly connected to the sliders on the two slide rails 3. Long cylinders 8 are installed on both sides of the moving seat 7. The two limiting clamping pieces 9 are respectively fixed on the output shafts of the long cylinders 8. The limiting clamping pieces 9 are arc-shaped clamping structures, and the limiting clamping pieces 9 are attached to the outer surface of the permanent magnet synchronous motor body 1. A plurality of positioning columns 14 are fixed on the moving seat 7, and the positioning columns 14 are adapted to the preset bolt holes on the mounting seat of the permanent magnet synchronous motor body 1. During the test, the preset bolt holes on the mounting seat of the permanent magnet synchronous motor body 1 are respectively sleeved on the positioning columns 14 to limit and fix the permanent magnet synchronous motor body 1. Then, the long cylinders 8 are respectively started, and the two limiting clamping pieces 9 approach and press on the permanent magnet synchronous motor body 1 to make its installation stable. Subsequently, the forward rotation mode of the driving motor 6 is started, and the moving seat 7 can be driven to move closer to the rotating roller 11 through the threaded rod 5, so that the output shaft of the permanent magnet synchronous motor body 1 is inserted into the connection hole 12. At this time, the driving motor 6 is stopped, and the permanent magnet synchronous motor body 1 is powered on and operated, which can drive the rotating roller 11 to rotate. Then, the staff can observe whether the permanent magnet synchronous motor body 1 is operating normally, and the operation is simple.

[0022] The implementation principle of a test device for a permanent magnet synchronous motor of a new energy vehicle in an embodiment of the present application is as follows: During the test, the preset bolt holes on the mounting base of the permanent magnet synchronous motor body 1 are respectively sleeved on the positioning posts 14, so that the permanent magnet synchronous motor body 1 is limited and fixed. Then, the long cylinders 8 are started respectively, and the two limit clips 9 approach and squeeze on the permanent magnet synchronous motor body 1 to make its installation stable. Subsequently, the forward rotation mode of the drive motor 6 is started, and the moving seat 7 can be driven to move closer to the rotating roller 11 through the threaded rod 5, so that the output shaft of the permanent magnet synchronous motor body 1 is inserted into the connection hole 12. At this time, the drive motor 6 is stopped, and the permanent magnet synchronous motor body 1 is powered on and operated, which can drive the rotating roller 11 to rotate. Then, the staff can observe whether the permanent magnet synchronous motor body 1 is operating normally, and the operation is simple.
