[0002] A brushless DC motor mainly consists of three components: an electronic switching circuit, a permanent magnet synchronous motor, and a position sensor. When a phase of the stator winding is energized, the current interacts with the magnetic field generated by the rotor poles to produce torque, driving the rotor to rotate. With the development of electronic technology and control theory, brushless DC motors have gradually improved and are widely used in various fields. Motor load testing equipment is one of the important means of evaluating motor performance by simulating the actual load conditions of the motor during operation.

[0003] Traditionally, load testing of brushless motors involves using screws to secure the motor under test. However, screws are only compatible with a single motor model. Installing the motor requires the operator to insert the motor shaft into a bushing while simultaneously securing it with the screws. This approach is inconvenient for mounting and dismounting the motor, results in low testing efficiency, and prevents the testing of different motor models. Therefore, we propose a load testing device suitable for brushless motors of various specifications. Summary of the Invention

It is sufficient to realize the relevant tests such as load testing, efficiency testing, torque / speed characteristic testing, overload testing and steering testing of the brushless motor.

[0019] In this embodiment, a sliding assembly 3 is provided on the other side of the substrate 1. The sliding assembly 3 includes a rod 32 that is slidably inserted into the interior of one side of the substrate 1. A support plate 31 is fixedly provided at one end of the rod 32. Support frames 33 are provided on both sides of the top of the support plate 31. The mounting plate 5 is provided on the top of the support frame 33. By sliding the rod 32 inside the substrate 1, the support plate 31 and the substrate 1 can move away from each other and move closer together, thereby realizing the test experiment of motors of different lengths.

[0020] In this embodiment, a moving mechanism 4 is installed on one side of the substrate 1 at the bottom of the sliding assembly 3. The moving mechanism 4 is used for at least the horizontal movement of the sliding assembly 3. The moving mechanism 4 includes a bearing seat 41 provided on the outer wall of one side of the substrate 1, and a lead screw 42 is connected to the bearing seat 41. One end of the lead screw 42 is fixedly connected to a rotating disk 43, and a lead screw nut 44 is threaded onto the external thread of the lead screw 42. A handle 45 is provided on the outer wall of one side of the rotating disk 43. When it is necessary to adjust the position of the sliding assembly 3, the operator holds the rotating disk 43 and drives the lead screw 42 to rotate on the bearing seat 41. The lead screw 42 drives the lead screw nut 44 to move horizontally, thereby driving the support plate 31 installed above the lead screw nut 44 to move horizontally, thereby realizing the adjustment of the position of the mounting plate 5.

[0021] In this embodiment, a mounting plate 5 is provided above the sliding component 3. Ear seats 51 are fixedly provided on both outer walls of the mounting plate 5. The ear seats 51 are connected to the top of the support frame 33. The ear seats 51 are connected to the support frame 33. At the same time, the ear seats 51 and the support frame 33 can be designed to be vertically adjustable as needed, so as to realize the adjustment of the height of the mounting plate 5.

[0022] In this embodiment, a pre-tightening mechanism 6 is provided on one side of the mounting plate 5. The pre-tightening mechanism 6 includes a second moving mechanism 61 with the same structure as the first moving mechanism 4. A traction shaft 62 is provided at the center of the mounting plate 5. The second moving mechanism 61 is connected to one end of the traction shaft 62. The other end of the traction shaft 62 is fixedly provided with an end head 63. Several hinge seats 64 are provided on the outer wall of the end head 63, and a pull rod 65 is provided on the hinge seat 64. Since the structure of the second moving mechanism 61 is the same as that of the first moving mechanism 4, the operation method is the same. The second moving mechanism 61 can drive the traction shaft 62 to move horizontally. When the traction shaft 62 moves to the right, the pull rod 65 is driven to move under the drive of the hinge seat 64. The angle of the pull rod 65 changes, thereby driving the clamping plate 8 to move up and down along the guide assembly 7 to achieve clamping and fixing of the motor inside the clamping plate 8.

[0023] In this embodiment, a guide component 7 is provided on the other side of the mounting plate 5. The guide component 7 is composed of a guide rail 71 fixed on one side of the outer wall of the mounting plate 5 and a slide saddle 72 slidably disposed on the guide rail 71. One side of the clamping plate 8 is fixed on one side of the outer wall of the slide saddle 72. When the clamping plate 8 moves, the slide saddle 72 slides on the guide rail 71 to achieve a guiding and stabilizing effect on the clamping plate 8.

[0024] In this embodiment, a plurality of clamping plates 8 arranged in a ring are installed on one side of the mounting plate 5 via a guide assembly 7. The inner wall of the clamping plate 8 is provided with a mounting groove 81, and the end of the mounting groove 81 is provided with an insertion hole 82 that penetrates the clamping plate 8. The replaceable pad 9 is slidably inserted into the inside of the mounting groove 81. The number of clamping plates 8 is preferably four. The four clamping plates 8 are arranged in a ring at equal distances along one side of the mounting plate 5, so that the four clamping plates 8 can open and close at the same time. When testing motors with different structures, the structure of the replaceable pad 9 is different. The replaceable pad 9 can be removed, and the inner side wall of the clamping plate 8 can be used to clamp and fix the motor with a circular outer surface. The replaceable pad 9 in the figure is a 90-degree right angle structure, which can be used to stably clamp the motor with a square outer surface using four replaceable pads 9. At the same time, the shape of the replaceable pad 9 is not limited to square, and can also be other angles to achieve clamping and fixing of motors with different styles.

[0025] In this embodiment, a replaceable pad 9 is provided on the inner sidewall of the clamping plate 8, and a positioning member 10 for positioning the replaceable pad 9 is provided on the outer sidewall of the clamping plate 8. The positioning member 10 includes a positioning seat 102 fixed to the outer wall of the clamping plate 8, a locking bolt 103 is threaded into the internal thread of the positioning seat 102, and a positioning block 101 is inserted into the internal thread of the insertion hole 82. After the operator inserts the replaceable pad 9 into the internal thread of the mounting groove 81, the positioning block 101 is inserted into the internal thread of the insertion hole 82, thereby limiting the position of the replaceable pad 9 inside the mounting groove 81. Then, the locking bolt 103 is used to lock the positioning block 101, which improves the effect of fixing the replaceable pad 9 inside the mounting groove 81.
