Description

Technical Field

[0001] The utility model relates to the technical field of vacuum stepping motor testing, in particular to a fixing device for vacuum stepping motor testing. Background Art

[0002] Motor torque is an important parameter in motor testing, especially in motor efficiency evaluation, where torque is an indispensable measurement. At present, the main methods for motor torque testing include the balance force method and the transfer method. The vacuum stepper motor of this technology is different from the traditional asynchronous motor in that its lower part is not supported and fixed. Figure 1 As shown, the vacuum stepper motor of the present technology includes a circular shell 100, a mounting plate 200 and a motor shaft 300, mounting holes 500 are provided at the four corners of the mounting plate 200, and a protruding connection portion 400 is provided on the motor shaft 300. When connected to an external connection, it is only supported by the mounting plate 200. Since the sizes of vacuum stepper motors vary (the diameter of the circular shell 100 ranges from a few centimeters to tens of centimeters), and the sizes of the mounting plates 200 are not the same, that is, the spacing between the four mounting holes 500 also changes with the size of the circular shell 100 and the mounting plate 200. Then, the traditional motor torque testing equipment cannot meet the installation support of vacuum stepper motors of multiple sizes.

[0003] Therefore, there is an urgent need to propose a fixture for testing a vacuum stepper motor with a simple structure and reliable installation and support. Utility Model Content
