An automatic winding machine for transformers and fan motors

Abstract

          The purpose of this research was to design, create, and analyte the performance of automatic winding machine for transformers and fan motors. The Arduino Mega 2560 microcontroller board was applied to control the operation of the motor unit using the pulse signal from the motor for counting the number of the winding machine for transformers and fan motors, the stepping motor got result from pressing the keypad and processing from the Arduino Mega 2560 board to stepping motor starts. From the experiment, the motor was used to drive the shaft with the core used as a spiral steel for arrange the coil can be moved left and right to keep the wire tidy and fulfill the block, and also intended for tense wire not too loose or too taut. There were two types of coil winding testing: 1) a hand-wound winding machine. (non-expert, expert) 2) an automatic winding machine with wire size used in experiment number 35, 36, 37 for 3 times to find the average speed () and to find the efficiency of automatic winding machine for transformers and fan motors by 9 experts. The evaluation result was good in every times and the rotational speed of the motor was not different, showing the average of 362-367 RPM. The coil winding machine was tested 100 turns 3 times with the wire size 35, 36 and 37 (sizes for electrical appliances) obtained an average of 1.20 minute using 12V, 3A stepping motor, 0.39 N and adjust angle 1.8°/step. They could pull the wire sizes from No. 24-37 or diameter from 0.17-0.55 mm and might replace by the hand winding, resulting in an accurate number of winding cycles.
