Controle de posição e velocidade utilizando inversor de frequência em uma máquina que faz a inserção do “chip” no cartão plástico: um caso de estudo

Abstract

This paper deals with the replacement of an electromechanical brake by a frequency inverter into a machine that makes the insertion of the "chip" on the card in an industry that manufactures smart cards (bank cards and SIM Cards Mobile). The machine in question has a motor that uses an electro mechanical brake to stop the engine in the correct position and make the insertion of the "chip" cards. With this brake wear problems occur constantly inserting chips and the adjustment becomes very difficult since the problem returns in a short time impacting in the production of cards once the machine spends much time for maintenance. The replacement of brake by a frequency inverter is an improvement that will make the production process more efficient, reducing the amount of waste production, also decreasing the down time for machine maintenance. Employee at work was one of WEG frequency inverters with the function of controlling the speed and the correct positioning of the machine for inserting the "chip".
