Development of a 3-Phase Induction Motor Control with power factor correction for Electrical Para Press Machine

Abstract

A rubber is an economic crop that generates income for agriculture. For Thailand, it has the second largest export value after rice. At present, the trend of growing rubber. It is a high yielding plant. The longevity planting value and the price of rubber when processed will be high. The farmers are interested in growing rubber. This paper presents the concept of a three-phase induction motor system with a power factor correction circuit for the electrical Para press machine, which improves machine efficiency and cost savings. The size of the three-phase motor is smaller than the single-phase motor at the same power. As well as in the design process, the present system of induction motor speed control using V/f control. The control system of motor is open loop. The current and voltage of the input are fed back. The PID is used to control power factor. The results of the research, that the controller can be used to control the speed of the induction motors. The test results of the control system using the brain system as a control system in the prototype system can be used to control the torque speed and power factor of the induction motor as required.
