step S502, determining each rotation angle of the equipment to be detected rotating for a whole circle based on a preset detection step length.

In one embodiment, the device under test is a motor under test, and the full rotation of the device under test means that the fixed member and the rotating member of the device under test rotate relatively for one circle, that is, rotate relatively for 360 degrees, rather than rotate 360 degrees integrally. Wherein, the fixed part of the equipment to be tested includes the stator, rotates the piece and includes the rotor, and in the moment testing process of the equipment to be tested, by initial state, 0, controlled relative rotation to 360 between the fixed part and the rotation piece in the equipment to be tested. Specifically, the fixed part in the device to be tested may be fixed and the rotating part may be controlled to rotate, or the rotating part in the device to be tested may be fixed and the fixed part may be controlled to rotate.

In one embodiment, the preset detection step length refers to a minimum interval rotation angle between a previous detection and a next detection when the torque of the device to be detected is detected. The preset detection step length can be set according to the detection requirement and is greater than or equal to the control precision of the driving equipment. For example, the control accuracy of the driving apparatus is 1 °, the preset detection step size must be set to be greater than or equal to 1 °.

In one embodiment, the controller determines each rotation angle of the device under test for a full rotation based on a preset detection step. Specifically, the number of rotations of the device under test for a full circle is determined based on a preset detection step, for example, if the preset detection step is set to 36 °, the number of rotations of the device under test for a full circle 360 ° is 10, which is equivalent to 10 detection times. And then, calculating each rotation angle of the equipment to be detected rotating for a whole circle according to the rotation times and the preset detection step length. And calculating the rotation angle corresponding to the rotation times by multiplying the obtained difference value by a preset detection step length so as to obtain each rotation angle of the equipment to be detected rotating for a whole circle, wherein the preset value is set to be 1. For example, the preset detection step is set to 36 °, and the number of rotations is 10. During the 1 st detection, the rotation angle of the device to be detected is 0 degrees, namely, the device to be detected is detected in the initial state, during the 2 nd detection, the rotation angle of the device to be detected is 36 degrees, during the 3 rd detection, the rotation angle of the device to be detected is 72 degrees, and so on, and during the 10 th detection, the rotation angle of the device to be detected is 324 degrees.

In step S504, one rotation angle is sequentially selected from the rotation angles as a target rotation angle.

In one embodiment, the controller sequentially selects one rotation angle from the rotation angles as the target rotation angle. Specifically, the controller selects a rotation angle corresponding to the number of rotations from among the rotation angles as a target rotation angle according to the number of rotations. And after the controller controls and detects the moment of the equipment to be detected each time, recording the rotation times and the corresponding target rotation angle so as to select the rotation angle as the target rotation angle next time.

Step S506, outputting a driving instruction to the driving device, where the driving instruction is used to instruct the driving device to drive the fixing element in the device to be tested to rotate by the target rotation angle.

In one embodiment, after determining the target rotation angle, the controller outputs a driving instruction to the driving device, where the driving instruction includes the target rotation angle, and the driving instruction is used to instruct the driving device to drive a fixing member in the device under test to rotate by the target rotation angle. Wherein the driving device comprises a stepping motor.

In one embodiment, the driving device may directly drive the fixing member in the device under test to rotate, or may drive the fixing member in the device under test to rotate through the middleware. When the driving equipment directly drives the fixing piece in the equipment to be tested to rotate, the output shaft of the driving equipment is directly in transmission connection with the fixing piece in the equipment to be tested, and therefore when the driving equipment is controlled to rotate, the output shaft of the driving equipment directly drives the fixing piece in the equipment to be tested to rotate. When the driving device drives the fixing piece in the device to be tested to rotate through the intermediate piece, the intermediate piece can be a clamp. The output shaft of the driving device is in transmission connection with the clamp, the device to be tested is accommodated in the clamp, and the clamp is equivalent to clamping a fixing piece of the device to be tested, so that the driving device drives the clamp to rotate, and the clamp drives the fixing piece in the device to be tested to rotate, so that the purpose of rotating the fixing piece in the device to be tested is achieved.

In one embodiment, the fixture may be a stationary turntable capable of rotating and locking the device under test. After the driving device drives the fixing piece in the device to be tested to rotate by the target rotation angle according to the driving instruction, the device to be tested is locked through the clamp so as to avoid influencing the starting of the device to be tested. In addition, the shape and material of the fixed turntable are not limited.
