The study was planned and developed to address the inadequacy of instructional materials in the performance of laboratory classes. The study aimed to test its functionality as well as evaluate its performance, as it would eventually be utilized as an educational demonstrator, specifically in the discipline of Electrical Technology. This motor control trainer allows students to conduct numerous motor controllers, and it includes an actual conveyor and incandescent lights as load demonstrators. This simulates the real motor controllers used in most industries. Industries would cease to exist if control systems were not adequately developed, coordinated, installed, and maintained.
The elements of the electrical system that starts, stops, and reverses motors that drive various mechanical equipment is known as motor controllers. This project may run a variety of motor controllers, including start-stop magnetic starters, multiple-push button magnetic starters, star-jog-stop magnetic starters, forward-reverse magnetic starters, manual sequential controller, automatic sequential controller, wye-delta magnetic starters, and the part-winding starting method.
As a result, the project benefits numerous stakeholders in academe and, indirectly, the labor market. The findings revealed a general weighted average of 4.83, a descriptive rating interpreted as highly functional, according to the evaluation results. Based on the findings, it is recommended that this be utilized as an instructional device and that creating a demonstrator is certainly doable; thus, comparable projects with greater capabilities should be produced. Basically, the Motor Control Demonstrator was developed and constructed in response to a perceived lack of training facilities/equipment.

Excerpt from the Book
Origin and Justification of the Study
Motors find the most practical use in our daily lives in the form of modern gadgets, technologies, and appliances. Motors are at the heart of many high-tech electronic, electromechanical, and electrical devices around the world. Even with these humorous advantages, motors were developed gradually, with many notable names and contributions from the scientific community.
Electric motors’ primary function is to transform electrical current into mechanical force. The history of motors can be traced back to the introduction of the foundations of electromagnetic induction. In the early 1800s, three well-known scientists, Oersted, Faraday, and Gauss, developed the fundamental concepts of electromagnetic induction. Andre Ampere and Hans Oersted created the most intriguing invention in 1820. They found that electric current generates a magnetic field, which led to the development of the basic DC motor ten years later. According to Moberg, who was quoted in Oraiz’s (1999) study, motors play a vital role in industry today. Industries would cease to exist if control systems were not adequately developed, coordinated, installed, and maintained. The element of the electrical system that starts, stops, and reverses motors that drive various pieces of equipment is known as motor control.
The development of instructional mock-up is indispensable to technology education. Wikipedia.com defines mock-up as a scale model, usually a full-sized replica, of a structure or apparatus used for instructional or experimental purposes. This motor control center trainer enables students to perform controls practical to industries with an actual conveyor and bulbs as load demonstrators. Even with the significant contribution of electric motors to the modernization of most industrial establishments, equating this advancement has remained a challenge that has plagued educational institutions to this day. As a state university, the University of Southeastern Philippines, like any other educational institution, is not exempted.
