- we are interested in an automatic garage gate system for a building. This system includes a gate that goes up or down, a motor to actuate the gate (pull, push) and sensors to collect information (gate open contact, gate closed contact). The sensors are all similar, each signaling to its controller that a contact has taken place. The user has a remote control to control with just two buttons: open, close. The operating principle of the system is as follows. Suppose the gate is closed. The user opens the gate by pressing the Open button on his remote control. He can stop opening by pressing the Open button again, the motor stops. Otherwise, the gate opens completely and triggers a Gate Open sensor which causes the motor to stop. Pressing the Close button causes the gate to close if it is open (partially or fully). The closing can be stopped by pressing the Close button again, the motor stops. Otherwise, the gate closes completely and triggers a Gate Closed sensor which causes the engine…arrow_forwardExplain the basic structure and working principle of the induction motor controller.arrow_forward23.
