Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a test stand for motors. Background Technology

[0002] Permanent magnet synchronous motors have advantages such as simple structure, small size, high efficiency, and high power factor. They have already achieved success in medium and low voltage motor applications in industries such as metallurgy (ironmaking plants and sintering plants), ceramics (ball mills), rubber (internal mixers), petroleum (oil pumping units), and textiles (twisting machines, spinning machines), gradually accumulating design and operational experience.

[0003] In order to collect the speed and torque data generated during the rotation of the motor in real time, so as to help customers develop motor drivers and match the motor application in various working conditions, it is necessary to design a test bench for motors. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a test bench for motors.

[0005] The objective of this utility model can be achieved through the following technical solution: A test bench for motors, comprising a platform, characterized in that a base plate is fixed on the platform, the base plate is detachably connected to a motor mount by fasteners, one end of the motor mount is connected to the body of a drive motor, the other end of the motor mount is connected to the body of a load motor, a sensor mount is connected to the motor mount by fasteners, the sensor mount is connected to the body of a dynamic sensor, one end of the dynamic sensor is connected to the output shaft of the drive motor by a first coupling, and the other end of the dynamic sensor is connected to the output shaft of the load motor by a second coupling.

[0006] The upper part of the motor base is connected to a protective cover by hand-tightening screws.

[0007] The protective cover is equipped with a handle.

[0008] The motor housing is detachably connected to the motor housing via fasteners and a stall block. The second coupling has a limiting part, and the stall block has a snap-fit ​​groove that cooperates with the limiting part.

[0009] Several lifting rings are also installed on the side of the motor mount.

[0010] Compared with existing technologies, this test bench for motors has the following advantages:

[0011] In this invention, the drive motor is responsible for active rotation, while the load motor is driven to rotate by the drive motor. The load motor generates a certain force during rotation, which can be set as needed to simulate a load of a certain power. At this time, the dynamic sensor in the middle collects the speed and torque data generated during the rotation of the motor in real time, so that it can be used to help customers develop motor drivers and match the motor in various working conditions.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figures 1-4As shown, the test bench for motors includes a platform 1, on which a base plate 7 is fixed. The base plate 7 is detachably connected to a motor mount 3 via fasteners. In this embodiment, the base plate 7 has a T-shaped mounting groove 7a, and the motor mount 3 has a strip-shaped notch 3a, so that the motor mount 3 can be easily installed onto the base plate 7 using fasteners. One end of the motor mount 3 is connected to the body of the drive motor 6, and the other end of the motor mount 3 is connected to the body of the load motor 4. The motor mount 3 is connected to a sensor mount 2 via fasteners. In this embodiment, the sensor mount 2 has a strip-shaped notch 2a, so that the sensor mount 2 can be easily installed onto the motor mount 3 using fasteners. The sensor mount 2 is connected to the body of a dynamic sensor 13. One end of the dynamic sensor 13 is connected to the output shaft of the drive motor 6 via a coupling 11, and the other end of the dynamic sensor 13 is connected to the output shaft of the load motor 4 via a coupling 12.

[0019] A protective cover 5 is connected to the upper part of the motor base 3 by a hand-tightening screw 14.

[0020] A handle 10 is installed on the protective cover 5.

[0021] The motor base 3 is detachably connected to the stall block 8 via fasteners. In this embodiment, the stall block 8 has a strip-shaped notch 8b, which allows the stall block 8 to be easily installed onto the motor base 3 using fasteners. The coupling 12 has a limiting part 12a, and the stall block 8 has a snap-fit ​​groove 8a that cooperates with the limiting part 12a. With this structure, when needed, the stall block 8 can be installed into the motor base 3 so that the snap-fit ​​groove 8a contacts the limiting part 12a, locking the load motor 4 under test from rotating. This can be used to perform stall tests on the motor.

[0022] Several lifting rings 9 are also installed on the side of the motor base 3.

[0023] In this embodiment, one is a drive motor 6 and the other is a load motor 4. Both motors are permanent magnet synchronous motors. The dynamic sensor 13 located in the middle is used to detect the specific amount of rotational speed and torque generated on the middle shaft during the rotation of the two motors.

[0024] In this invention, the drive motor 6 is responsible for active rotation, while the load motor 4 is driven to rotate by the drive motor 6. The load motor 4 generates a certain force during rotation, which can be set as needed to simulate a load of a certain power. At this time, the dynamic sensor 13 in the middle collects the speed and torque data generated during the rotation of the motor in real time, so that it can be used to help customers develop motor drivers and match the application of the motor in various working conditions.

[0025] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
