Embodiment Construction

[0012] refer to figure 1 Shown is a hardware architecture diagram of a preferred embodiment of a stepping motor testing machine of the present invention. The machine includes an input device 3, a control device 2, an input and output controller 4, a stepper motor driver 6, and a stepper motor 7 connected in sequence, and a waveform generator is also connected between the control device 2 and the stepper motor controller 6. 5, the control device 2 is also connected to the display device 1.

[0013] The display device 1 is used to display the parameters set by the input device 3 and information during operation. The information in the running process includes the remaining running time (namely: the time until the end of running) and the rotation state (including forward rotation state, pause state and reverse rotation state). The remaining time includes: remaining time for testing, remaining time for forward rotation, remaining time for reverse rotation, and remaining time for...

Abstract

The invention provides a step motor test method adopting an input device, a control device, an input-output controller and a step motor driver which are sequentially connected to test whether the step motor can be qualified; wherein, a waveform generator is connected between the control device and the step motor driver. The method includes the following steps: parameters containing the running direction and test time of the step motor which are needed to be tested for the step motor are set through the input device; the input-output controller is controlled by the control device to send out control instructions and the wave generator is also controlled by the control device to send out impulse signals so as to drive the step motor to run according to the set running direction; the control device judges whether the step motor runs normally in the test time. The invention also provides a step motor test system. Adopting the test system and method can quickly and accurately complete the test to the step motor.

Description

technical field [0001] The invention relates to a stepping motor testing system and method. Background technique [0002] Improving and ensuring product quality is an important part of corporate activities. In order to improve and guarantee product quality, enterprises must test products to obtain quality information of products and their manufacturing processes, and control the manufacturing process of products according to these information - carry out correction and compensation activities, so that the rate of waste and defective products and repaired products Minimize, and ultimately ensure the stability of the product quality formation process and the consistency of the output product. [0003] As we all know, the stepper motor has the characteristics of simple structure, high reliability and low cost. It can directly convert the digital pulse signal into angular displacement, and can control the angular displacement of the motor by controlling the number of pulses to ...
