Description

Technical Field

[0001] The utility model relates to the technical field of motor testing machines, in particular to a motor testing machine. Background Art

[0002] A brushless DC motor, consisting of a motor and a driver, is a typical mechatronic product. Because it operates in an autonomous manner, it does not require a separate starting winding on the rotor, as is the case with synchronous motors that start under heavy loads under variable frequency speed regulation. It also avoids oscillation and loss of step when subjected to sudden load changes. Torque refers to the moment exerted by an object during rotation or bending. Current torque testing of a product typically involves bending it with a motor or wrench to observe whether the deformation meets the required toughness.

[0003] After searching, it was found that the application number is CN202221808691.4, and the name is a test machine for the output torque of a brushless motor. The application proposes that the existing test machine for the output torque of a brushless motor is not convenient for fixing the motor stably during use, which easily causes the motor to shake when testing the torque, affecting the test accuracy, and the motor fixing operation is cumbersome and inconvenient to use. The height of the support frame can be conveniently adjusted by the telescopic part, which further facilitates the adjustment of the position of the motor and facilitates torque testing of motors of different sizes; a limit frame is fixedly installed on the support frame, and the shape of the limit frame is an inverted U shape. The limit frame is provided with a horizontal clamping component and a vertical clamping component, which is convenient for simultaneously fixing the motor The machine can clamp the motor horizontally and vertically, quickly fix the motor, and keep the motor stable during torque testing, which is convenient to use. However, in actual use, the horizontal clamping component and the vertical clamping component run synchronously. When the width of the motor is consistent and the height is different, it is easy to cause the vertical clamping component to be unable to clamp the motor after the horizontal clamping component is clamped, resulting in problems with its clamping flexibility and convenience of use, and the clamping force is insufficient. Further improvements can be made. At the same time, after the motor is fixed, the motor cannot be moved to dock with the tester, which means that the staff needs to calculate the docking distance when fixing the motor, and there are certain inconveniences in adjusting the fixation. Further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
