Power setting based on load using phase control on conveyor system

Abstract

The advantage of using conveyors that have been successfully designed through this research is in the power settings based on the load’s condition on the conveyor in which we hope that the system performance would be better in terms of electrical power usage. The conveyor’s speed control system used the PWM (Pulse Width Modulation) method, a pulse width setting to supply current for the engine. Inputs come from a Load cell censor that measures the weight together with the motor’s activator. Microcontroller ATMega328 is used as a controller of the system. When the system is activated, the controller will activate the motor activator with the PWM signal based on the load weight The Microcontroller then identifies the load weight and determines the PWM count to set the corresponding power and speed. Through the optocoupler, Microcontroller provides the pulse to control the gate on the TRIAC (Triode for Alternation Current), which acts as a phase controller connected to the induction motor to power the conveyor. The result of this research shows that the heavier the load is, the generated power will correspondingly be higher.
