Description

Technical Field

[0001] This utility model relates to the technical field of linear stepper motor testing equipment, and specifically to a linear stepper motor testing equipment. Background Technology

[0002] A stepper motor is a type of electric motor that converts electrical pulse signals into corresponding angular or linear displacement. For each input pulse signal, the rotor rotates by an angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, stepper motors are also called pulse motors. For their application, it is necessary to test the lead screw thrust and service life of the linear stepper motor in order to ensure the efficiency of the stepper motor itself.

[0003] Existing linear stepper motor testing equipment tests the thrust by adding or removing weights to the nut, thus changing the weight to measure the thrust. For example, a linear stepper motor lead screw thrust and durability testing fixture disclosed in patent number CN202323654366.4 uses this method. However, this method requires frequent addition and removal of weights, as well as calculation of the number of weights to obtain the test results, making the testing process cumbersome and ineffective. Therefore, there is an urgent need for a linear stepper motor testing device to solve these problems. Utility Model Content

[0008] Furthermore, the linear stepper motor body is fixed to the fixed plate by bolts, one end of the lead screw is fixed to the output shaft of the linear stepper motor body, and the other end of the lead screw is connected to a support.

[0014] Furthermore, one end of the force gauge is fixed to the fixing plate by screws, and the display screen is electrically connected to the force gauge.
