Automatic Motor Detection and Control System (A.M.D.A.C.S.)

This Rapid evolution of digital technology has improved the ease of access to increase the productivity and reduce production cost. For every motor to use it efficiently for various application first tasks is to control its speed with regulation and soft start. So, we decide to make such system which can control speed of all motor (e.g. AC, DC, Universal). Also to detect which motor is connected at load side with its regulation. Single phase alternating current (AC) motors are well known as general purpose motors. In many different situations they perform better. These AC motors work great for systems that are hard to start because they need a lot of power up front. Where speed needs to be controlled Direct current (DC) electric motors work for the situations. It has a stable and continuous current. In the industry DC motors were the first and earliest motors used. They were found, however, to not be as good at producing power over long lengths. Actually on the principle AC as well as DC Universal Motor can be controlled. So, we controlled Universal motor on the principle of DC motor. Some other Control techniques for mono phase motors i.e. Universal motor or any AC loads are based on phase-angle adjustment. This The TRIAC is turned ON by the control signal coming from the microcontroller by giving some delay after the zero crossing, and get turned OFF when its current reaches a zero value. This concept is the same for positive and negative voltage. For Detection of motor we used IR and depending upon voltage if motor getʹs its rpm we detect motor. Also for regulation we used IR pair as tachometer and detect rpm of motor so after connecting load if motor speed decreases, we check input rpm and then compare both and accordingly we maintain its rpm.
