Analysis of the Mechanical Performance Estimation of Electric Motors Used in the Drive of Deep Well Pumps

V Vertical hollow shaft insert ignore into journalissuearticles values(VHS); deep well pumps are one of the pump types commonly used in agricultural irrigation. 3-phase asynchronous electric motors are used to drive these types of  pumps. In this study, the main goal is to analyze the manufacturer’s motor catalog data with Kloss formula and estimate the instantaneous rotor torque of these motors with the least error. For  this aim, Nominal speed, breakdown torque and rotor speed at breakdown torque used in the study as the manufacturer`s data. By this way, it became possible to estimate the mechanical  performance of today`s manufactured motors with the least possible measurement and error rate. Also, the results showed that the torque values which were calculated by using the Kloss formula given in the literature is giving us a chance a chance to easly make inferences from the manufacturer data efficiently
