Abstract
The invention relates to a comprehensive property testing system for a stepping motor. The testing system is composed of a servo motor (101), a motor mounting bracket (102), a first coupling unit (103), a, torque sensor (104), a second coupling unit (105), a switching shaft (106), a to-be-tested motor mounting bracket (107), an adapting flange (108), a first sliding block (109), a second sliding block (110), a third sliding block (111), a guide rail (112), a mounting flange (201), a motor bracket (202), a connecting shaft (203), an input coupling unit (204), a load torque sensor (205), an output coupling unit (206), a hysteresis brake (207), a hysteresis mounting bracket (208), a hysteresis sliding block (209), a torque sensor sliding block (210), a motor sliding block (211), a slide rail (212) and a controller. According to the invention, the testing precision of the system is high; and characteristics testing requirements of positioning / maintaining torques and loads having different precisions, levels, and ranges can be met by selecting torque sensors with different torque ranges and different precision and resolution ratios and servo motors.
Description
technical field [0001] The invention belongs to the testing field and relates to a stepping motor testing system, which can be used for measuring the positioning torque, holding torque and load characteristics of the stepping motor. Background technique [0002] The stepper motor is an open-loop control stepper motor that converts the electrical pulse signal into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the stepper motor only depend on the frequency and number of pulses of the pulse signal. Unaffected by load changes, it has excellent start-stop and reverse response, position accuracy, good position repeatability, high reliability, simple structure, low cost, and a wide speed range, and has been widely used in various automation controls system. [0003] After the stepper motor is developed, it is generally necessary to measure its positioning torque and holding torque. The positioning torque refers to the loc...
