A stepping motor performance testing equipment

Abstract

The invention provides a stepping motor performance test device which comprises a motor installation support used for the installation of a stepping motor; a balancing weight used for applying an axial force to a stepping motor lead screw by the weight thereof; a force distribution cap used for transmitting the axial force of the balancing weight coaxially to the stepping motor lead screw; and a movable support / guiding column used for enabling the balancing weight to move up and down flexibly and to be loaded to the stepping motor lead screw accurately. When the tested stepping motor is under a given load and a given instruction condition, the test device is capable of testing the mechanical performance of the stepping motor such as the displacement, the force moment and the rotation angle and the electric performance such as the current and the power, and data collection and processing and result printing are completed by test software. The stepping motor performance test device has the advantages that the testing precision is high, the response time is short, the automatic degree is high, the integral structure is firm, the maintainability is high, and the test device is applicable to a severe environment and is high in practicability.

Description

technical field [0001] The invention relates to a stepping motor performance testing device, in particular to a stepping motor performance testing device with high precision and fast response speed. Background technique [0002] As an important driving and execution equipment, stepping motor is widely used in aerospace, weaponry, industrial and agricultural control, precision machinery and medical equipment and other fields. Important test equipment for commissioning and delivery acceptance, the quality of the stepper motor test system directly affects the performance and accuracy of the stepper motor and mechanical equipment. [0003] In view of the fact that the current motors are prone to problems such as single function, overload and step loss, high power consumption and heat generation, low degree of automation, and difficulty in high and low speed control during operation, it requires a variety of equipment to complete a stepping motor or mechanical equipment. The per...
