Desarrollo de una balanceadora electrónica para rotores de motores eléctricos para la empresa Siproelectrik S.A.

Abstract

An important problem that occurred in the electric motors and generators it’s the excessive vibrations, what it causes several damages that affect the mechanical and electrical components reducing like this useful life to any rotary machine. Proximately the 40% of these vibrations that occurred due a fault in the rotor, originated to an overload, constant blows r other wises. To this reason in the Siproelectrik S.A factory was build an electric balancer, which support a weight near to the 2T (tons), allowing analyze the electric rotor’s vibrations in the powerful machines. This balancer has the possibility to adjust to some kind of rotor’s form what it has different moving parts and different specific points of subjection where the sensors are placed; there are piezoelectric accelerometer and digital tachometer. The method to determine the point of correction it’s known like four runs without phase and consist to put weights in specific points to rotor that generate different amplitude values and with the use to mathematics resources select the exactly compensation point, reducing these exes to vibrations and achieving a uniform turn giving a good performance to the rotary machine assembled and commissioning.
