[0030] Reference Figures 1 to 4 The embodiment of the present invention provides a non-contact magnetic drive detection experimental device, which mainly includes a mounting platform 10, a motor 20, a magnetic drive wheel 30, a magnetic driven wheel 40, a torque sensor 50 and a torque and speed measuring instrument.

[0031] The motor 20 is mounted at one end of the mounting platform 10. Specifically, the motor 20 is fixedly mounted by a left L bracket 71 and a right L bracket 72. A magnetic drive wheel 30 is fixedly mounted on the output shaft of the motor 20. In this embodiment, the speed of the motor 20 is controlled by a loading controller.

[0032] The magnetic driven wheel 40 is mounted on the other end of the mounting platform 10. Specifically, the magnetic driven wheel 40 is mounted on the mounting platform 10 through a T-shaped driven wheel bracket 73. The magnetic driving wheel 30 and the magnetic driven wheel 40 are arranged opposite to each other and have a preset spacing, and the size of the preset spacing is adjustable.

[0033] The magnetic driven wheel 40 is installed on one side of the driven wheel bracket 73 through a bearing, and the torque sensor 50 is coaxially installed on the other side of the driven wheel bracket 73 through a coupling 80. The magnetic driven wheel 40 is coaxially arranged with the torque sensor 50. The torque sensor 50 is connected to a torque speed measuring instrument. The motor 20 drives the magnetic driving wheel 30 to rotate, and the magnetic driven wheel 40 is rotated by the magnetic field interaction force. The torque sensor 50 collects the magnetic force, magnetic torque and speed of the magnetic driven wheel 40, and the torque speed measuring instrument measures the magnetic force, magnetic torque and speed.

[0034] The non-contact magnetic drive detection experimental device can perform real-time detection of the magnetic force, magnetic torque and rotation speed of the non-contact magnetic drive mechanism. At the same time, by adjusting the size of the preset spacing, the effect of the spacing on the magnetic force, magnetic torque and rotation speed of the magnetic drive mechanism can be tested, which is very convenient and quick.

[0035] Preferably, in order to achieve the size adjustment of the preset spacing, a first adjustment groove 11 and a second adjustment groove 12 are provided on the mounting table 10 along the relative layout direction of the magnetic driving wheel 30 and the magnetic driven wheel 40, the motor 20 is installed in the first adjustment groove 11, and the installation position of the motor 20 in the first adjustment groove 11 is adjustable along the relative layout direction, the magnetic driven wheel 40 is installed in the second adjustment groove 12, and the installation position of the magnetic driven wheel 40 in the second adjustment groove 12 is adjustable along the relative layout direction.

The vertical position of the magnetic driven wheel 40 can be adjusted by adjusting the installation position of the magnetic driven wheel 40 in the third adjustment groove, so that the magnetic drive wheel 30 and the magnetic driven wheel 40 are staggered, which is convenient for realizing real-time detection of magnetic force, magnetic torque and rotation speed under the staggered situation.

[0037] In some embodiments, magnet holes are provided on opposite sides of the magnetic driving wheel 30 and the magnetic driven wheel 40, the magnet holes are distributed along the circumferential direction, permanent magnet units 60 are placed in some or all of the magnet holes, and the permanent magnet units 60 on the magnetic driving wheel 30 and the magnetic driven wheel 40 are arranged in the same manner. The number or distribution of the permanent magnet units 60 can be adjusted, and the corresponding magnetic force, magnetic torque and speed are detected in real time by a torque and speed measuring instrument.

[0038] In order to study the influence of the distribution mode of the permanent magnet units 60 on the magnetic force, magnetic torque and rotation speed, the permanent magnet units 60 may be distributed at equal intervals or randomly.

[0039] Furthermore, in order to study the influence of the shape of the permanent magnet unit 60 on the magnetic force, magnetic torque and rotation speed, the shape of the magnet hole is any one of circular, elliptical or polygonal.

[0040] At the same time, the method for testing using the non-contact magnetic drive testing experimental device includes the following steps:

[0041] The preset distance between the magnetic driving wheel 30 and the magnetic driven wheel 40 is adjusted, and the magnetic force, magnetic torque and rotation speed of the magnetic driven wheel 40 are measured by a torque and speed measuring instrument; in this way, the influence of the preset distance on the magnetic force, magnetic torque and rotation speed can be obtained.

[0042] The spatial distribution of the magnetic driving wheel 30 and the magnetic driven wheel 40 is staggered so that the magnetic driving wheel 30 and the magnetic driven wheel 40 are not coaxial, and the wheelbase between the magnetic driving wheel 30 and the magnetic driven wheel 40 after the stagger is defined as a. The magnetic force, magnetic torque and rotational speed of the magnetic driven wheel 40 are measured by a torque and speed measuring instrument when the wheelbase is a. In this way, the influence of the staggered wheelbase a on the magnetic force, magnetic torque and rotational speed can be obtained.

[0043] By changing the distribution pattern and number of the permanent magnet units 60 on the magnetic driving wheel 30 and the magnetic driven wheel 40, the magnetic force, magnetic torque and rotational speed of the magnetic driven wheel 40 are measured by a torque and speed measuring instrument; in this way, the influence of the number and distribution pattern of the permanent magnet units 60 on the magnetic force, magnetic torque and rotational speed can be obtained.

[0044] The shapes of the permanent magnet units 60 on the magnetic driving wheel 30 and the magnetic driven wheel 40 are changed, and the magnetic force, magnetic torque and speed of the magnetic driven wheel 40 are measured by a torque and speed measuring instrument. In this way, the influence of the shape of the permanent magnet unit 60 on the magnetic force, magnetic torque and speed can be obtained.
