Training device of Training System Training System

 

The tr--ning device of cross -current speed adjustment tr--ning is based on the requirements of "Electric Power Drag Automatic Control System", "DC Specific Introduction", "AC Volcanic Speed Speed", "** M--ntenance Electrician (Traveling DC Specific Part)" textbook outline. A set of modern comprehensive motors and driving series tr--ning products launched in cooperation with colleges and universities in colleges and universities and vocational tr--ning technology. The m--n tr--ning and assessment of the tr--nees of the tr--nees of the interchange inverter and DC speed regulating device are m--nly tr--ned and evaluated the system application capabilities of AC inverters and the well -controlled motor load. Electric frequency conversion controls various typical working status; carefully designs the m--n circuit, control circuit and DC motor load of DC speed regulating device, enabling students to master the typical working status of DC motor speed regulation through tr--ning.
