The system is characterized in that the software part is embedded in an operating system of the hardware part; in the hardware part, a movement control card and a data acquisition card of a computer are both connected with a test line, the test line is connected with a voltage signal feedback of rotary speed and current and an AC-DC motor, the AC-DC motor is coaxially connected with a magnetic powder brake, the data acquisition card is connected with the magnetic powder brake by a magnetic powder brake controller, and the remote programmable control loading is completed. The system of the invention has the advantages of digitization, intelligence, networking, simulating and systematization.

Description

technical field [0001] The invention relates to an AC / DC speed regulation and loading system suitable for teaching purposes, in particular to a full digital control AC / DC speed regulation and loading system for teaching. Background technique [0002] Since domestic higher vocational colleges and automation majors in colleges and universities all need to learn professional courses such as electrical machinery, motor drive, power electronics technology, and automatic control systems, the learning process is rather boring; through experimental teaching, theory can be combined with practice. It can better deepen the process of theoretical learning and grasp its essential meaning; while theoretical teaching is the basis of experimental teaching, students should learn to use the theoretical knowledge they have learned to analyze and solve various problems in the actual system during the experimental process , improve hands-on ability; at the same time, verify the theory through ex...
