Substituição e melhoria do sistema de acionamento do motor em máquina de lavar roupa industrial

Abstract

This paper presents the development of a circuit for driving a three phase induction motor, installed in an industrial washing machine for a hotel in the town of Telêmaco Borba, Pr For the drive we used a frequency inverter in order to replace the original drive with defective braking system in the washing cycle. With the replacement and improvement of driving the machine working again in accordance with the foregoing features, the binary inputs it was possible to speed control for the two cycles using only one motor. The simplification of the circuit and elimination of three-pole contactors used in the power circuit, easier maintenance and troubleshooting of the drive washing machine. Through ramp acceleration and deceleration eliminated leaps on drive belts from the departures direct and abrupt stops the engine reducing breaks bearings.
