Vector controlled comparative studies for line starting performance induction motor of a conveyor system

Abstract

The main functions of conveyor system or movement machine are to move some goods from the origin place to determined place. The main composition of conveyor is electric motor as driver and gearbox as reduction of gear transmission and controller as the manager of electric motor starting. The components that need serious attention are the controller and electric motor. The stability control of conveyor system is in the starting current of the induction motor. The starting performance of induction motor, for example in conveyor application, requires rapid dynamics and precise regulation; hence the need of direct control is becoming an urgent demand. This type of control provides an independent control of torque and flux, which is similar to a separately excited induction motor and offers a number of attractive features. Induction motor has a high starting torque while separately i n d u c t i o n motor can operate above the base speed in the line starting current. This paper compares study and highlights the effectiveness of the different proposed vector controlled methods for a line starting performance of induction motor model parameter, using both simulation and manufacturers measured experimental data. Simulation studies are conducted to the induction motor drives as to obtain the performance of DC series motor below base speed and the separately excited DC motor above speed[4]. A steady state and transient analysis of the induction motor is performed below and above base line starting current.
