摘要

The invention relates to electromechanical systems, and more particularly to a drive force automation facilities, and can be used in the learning process as the training bench of automated electric device for studying soft start induction motor constructed on the basis of the frequency converter. Training stand for automated electric drive is designed to increase efficiency of studying soft starter of the asynchronous motor due to the expansion of the demonstrated process to disperse the asynchronous machine. The stand is further provided with a switch for switching the four chains at two fixed positions, four normally open contacts, a microcontroller, the first and second inputs of which are connected to two programmable logic output of the soft starter, first, second, third, fourth programmable inputs soft starter each through one of the four circuits in the first fixed position connected to the four outputs of the microcontroller, and in the second fixed position switching switch These four inputs, each programmable through a corresponding normally open contact connected to a source of DC voltage 24 V, which is part of the soft start induction motor.
