Abstract

The objective of this research was to 1) develop a 3-phase electric motor control experimental kit  2) promote skills in connecting circuits to control 3-phase electric motors of students of the Faculty of Industrial Technology, Phibunsongkhram Rajabhat University  3) study the satisfaction of learning with a 3-phase electric motor control experimental kit. The population of research was the second year undergraduate students in mechanical engineering who are studying in semester 1/2565 of 15 students. The research instruments consisted of a 3-phase electric motor control experiment kit, 5 experimental worksheets, practice skills test for connection of a 3-phase electric motor control circuit, and the satisfaction questionnaire on learning with a 3-phase electric motor control experiment kit. The practical skills test showed a reliability value of 0.88 and the power classification value in the range of 0.31 – 0.85. The satisfaction questionnaire had a reliability value of 0.81. The parameters used in the research were the efficiency of the 3-phase electric motor control experiment kit (E1/E2), mean (M), standard deviation (S) and the paired-samples test (T-Test).The results of the research showed that1. The efficiency of the 3-phase electric motor control experiment kit was 89.90/90.17. 2. The population had higher scores in practical skills measurements after learning than before learning by statistically significant at the 0.05 level. 3. The population's satisfaction with learning by the 3-phase electric motor control experiment kit was at the highest level by has to mean of 4.55
