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.
