Development of a Trainer on Motor Controls for Engineering Students

Discipline: Education, Genetic Engineering, Mechanical Engineering



The study aimed to collect different types of control circuits for the operation of motors; determine the devices needed for each of the different types of controllers; set up the devices in a board to form a trainer; and evaluate the trainer in terms of some parameters.

The trainer contained magnetic contactors and overload relays, timing relay, pilot lamps, pushbuttons, and binding post.  These devices can be interconnected to form different types of motor controls like Across-the-Line Starter, Jog Control, Wye-Delta Starter, Immediate Reversal, Forward – Reverse Starter and Primary Resistance Starter.

Upon the final set-up of all the devices on a board, selected students in electrical engineering used this trainer for motor control.  They evaluated the acceptability of the trainer in terms of usefulness, effectiveness, efficiency, functionality, and reliability.

This trainer will benefit students who need to understand the basics of industrial motor control.  They will be introduced to industrial motor controls with the understanding that the individual must be a qualified person to be able to work on the equipment.  With that in mind the person will learn about the contraction, operation, and how to avoid the hazards associated with electrical motor controls.

This will also help instructors in teaching motor controls.  They will provide students with the proper information that they need in the connection of the different control circuits.  Motor control is often taught with “chalk and blackboard” but with this trainer teachers can teach students with real devices and wirings and not merely using the imagination.
