Inverter speed regulation system experimental device

 

This device uses a typical high-performance and multi-function FR-A740 variable frequency frequency frequency speed regulator (380V, 0.75kW) as the host, and the outer pulse coder electrical mechanism speed measurement system. The entire device can complete all functional experiments of the opening and closed -loop system and the frequency conversion speed. The open structure allows students to comprehensively learn and master the structure principles of frequency adjustment speed, detection and m--ntenance. It is suitable for large and high school colleges, vocational schools, and technical school automation professional supporting teaching and open experiments

Fourth, experimental table: aluminum and wood structure, the desktop is fire, waterproof, wear -resistant high -density board, and beautiful shape. The high -quality aluminum alloy made of special molds is used as a framework. The surface of the aluminum alloy is oxidized, durable, beautiful and generous, in line with modern aesthetics. The desktop is fire, waterproof, wear -resistant high -density board, and the lower part of the table is equipped with a storage cabinet.

The tolerance coordination and technical measurement are a very important technical basic course, skills and application courses for mechanical majors. It is an important technical requirement on the design drawing of mechanical parts, and it is also an important part of the static and dynamic geometric accuracy of mechanical products. With the development of science and technology and the improvement of production level, the geometric accuracy of mechanical products has also made increasing requirements. The geometric accuracy has formed an independent technical discipline, and it is subject to the academic and engineering and technical circles. The people attach great importance to it.

This series of installations are based on the actual requirements of design engineers for the actual requirements of accuracy design, on the premise of actual teaching situation and teaching object conditions, and carefully developed a set of teaching products combining theory and reality. It is suitable for parts of ordinary high schools, employee middle schools, vocational middle schools, vocational schools and undergraduate colleges.
