[0002] The motor includes a stator and a rotor. The rotor is the rotating part of the motor. By cooperating with the stator, it can convert electrical energy into mechanical energy. As an important component of the motor, the rotor needs to be tested during the production and assembly process to ensure the quality of the motor.

During the inspection, the rotor needs to be rotated to simulate its working state, and it is convenient to check whether the rotor is damaged. However, the existing device for driving the rotor to rotate is complicated in structure, and when the rotor is small and light, the rotor is prone to slipping and jumping during rotation, resulting in poor rotation stability.

[0043] The driving motor 2 provides the rotational power of the device, drives the driving wheel 4 to rotate, and the driving wheel 4 drives the belt 6 to operate. The belt 6 contacts the rough surface of the iron core of the rotor 8, and the belt 6 drives the driven wheel 5 and the rotor 8 to rotate. Through the setting of the magnet 3, the magnetic force of the magnetic field is generated, giving the rotor 8 a downward suction force, thereby increasing the wrapping surface between the rotor 8 and the belt 6, increasing the friction, avoiding the rotation slippage and jumping of the rotor 8 during the transmission process, ensuring the stability of the rotation of the rotor 8, and improving the accuracy and efficiency of the rotor detection.

[0044] Preferably, the drive motor 2 is a stepper motor, and the speed regulation is convenient. The drive motor 2 can set parameters by the human-machine interface and be controlled by PLC to achieve the purpose of adjusting the rotation speed of the rotor 8. Preferably, the belt 6 is a seamless round belt to ensure the friction between the rotor 8 and the belt 6. The magnet 3 is a strong magnet, and / or the magnet 3 is in the shape of a cylinder with a larger upper part and a smaller lower part, and / or the lower part of the magnet 3 is embedded in the supporting side plate 1.

When the position adjustment is completed, the positioning plate 745 is screwed into the bearing seat 741 by bolts to achieve the positioning of one of the bearing plates 743.

[0051] Preferably, in this embodiment, two support lifting adjustment mechanisms 73 are arranged on the support level adjustment mechanism 74 to adjust the height of the first support member 71 and the second support member 72 and the distance between the first support member 71 and the second support member 72. Specifically, the two support seats 731 are fixed on the two bearing plates 743 respectively.

[0052] In order to facilitate adjustment of the tension of the belt 6 , at least one tensioning wheel 9 is preferably provided on the side of the supporting side plate 1 , and the belt 6 is wound around the tensioning wheel 9 .

[0054] In order to facilitate the modularization of the device and to facilitate its application to various machines, a bottom plate 12 is preferably further provided, and the supporting side plate 1 and the two bearing seats 741 are both provided on the bottom plate 12. Preferably, the bottom plate 12 is provided with a first limiting groove 121, and two second limiting grooves 122 perpendicular to the first limiting groove 121 and penetrating the first limiting groove 121, the two second limiting grooves 122 are arranged opposite to each other, the bottom of the supporting side plate 1 is arranged in the first limiting groove 121, and the bottoms of the two bearing seats 741 are respectively arranged in the two second limiting grooves 122, so as to improve the stability of the supporting side plate 1 and the two bearing seats 741 on the bottom plate 12.

[0055] See also Figure 1 Preferably, a sensor 13 is provided on the supporting side plate 1, and a laser 131 emitted by the sensor 13 is used to know whether there is a rotor 8 to be detected on the first supporting member 71 and the second supporting member 72, which is convenient and quick to operate the subsequent components.

[0056] When the utility model is in use, the driving motor 2 is started, driving the driving wheel 4 to rotate, the driving wheel 4 drives the belt 6 to operate, the belt 6 drives the driven wheel 5 and the rotor 8 to rotate, and at the same time, the magnet 3 has the magnetic force of the magnetic field, sucking the rotor 8 downward, and increasing the friction between the rotor 8 and the belt 6, so as to avoid the rotation slippage and jumping of the rotor 8 during the transmission process. When it is necessary to realize the rotation of rotors 8 of different models, in order to detect rotors of different models, according to the outer diameter of the core of the rotor 8 and the length of the core shaft, the support horizontal adjustment mechanism 74 and the two support lifting adjustment mechanisms 73 are used to adjust the spacing between the first support member 71 and the second support member 72, and the height of the first support member 71 and the second support member 72, so as to replace the rotor. When it is necessary to adjust the tension of the belt 6, the tensioning wheel 9 is moved along the strip hole 11 to adjust the position.
