DC motor forward and reverse drive system for opening and closing of plastic house

摘要

This study is about the directional drive device of DC motor for plastic shed switch.Generally speaking, plastic shed is the growth condition or temperature of cultivated plants,According to the humidity, the plastic seat or plastic film shall be properly opened and closed,The purpose of this study is to provide DC motor rectifier drive equipment suitable for this kind of plastic shed switch,In order to identify the positive and negative power supply in the drive motor (10), the power supply unit (20) and of the polarity conversion circuit are installed,B contact 30b directly connected to common contacts 30c and 40c connected to output terminals 20a and 20b of the power supply unit 20 and terminals 10a and 10b of the driving motor 10, respectively. 40b and limit switches 30 and 40 having a contacts 30a and 40a connected to terminals 10a and 10b of the driving motor 10 through diodes D1 and D2, respectively. DC motor forward and reverse drive system for opening a plastic house is provided.
