Development and Efficiency Finding of an Electric Propulsion Training Set Using a Brushless DC Electric Motor

Abstract

This research aims to: 1) develop a training set for electric propulsion using brushless DC motors, 2) determine the efficiency of the electric propulsion training set using brushless DC motors, and 3) compare the performance results based on the average scores of pre- and post-training tests using the brushless DC motor electric propulsion set for teaching Electric Propulsion Technology in the Bachelor Degree of Engineering Program, in Electrical Technology and Automatic Control Systems, academic year 2022 of Siam Technology College. The research tools included a training set, supplementary documents for the training set, and assessment questionnaires. The experimental group consisted of 42 third-year undergraduate students majoring in Electrical Technology and Automatic Control Systems in the first semester of academic year 2022.

The research findings indicated that: 1) the developed training set employed the brushless DC motor as planned. 2) The efficiency of the training set was validated by the experts reached the average of each aspect in the range of 4.389-4.619 or a good level with the IOC of 0.9 higher than the set criteria at 0.5. 3) The achievement scores during the learning process 90.27/83.55 higher than the set criteria at 80/80.  Statistical analysis using the t-test reveals that the students achieved significantly higher learning outcomes with a statistical significance level of 0.01.
