Bancada de teste para comprovação de eficiência em rebobinamento de motor elétrico trifásico, com base na leitura do torque do motor

Abstract

In this work, a bench test will be developed to prove the mechanical maintenance of the industrial electric motor, using two motors mechanically coupled and driven by two frequency inverters. The objective is to apply no motor to be tested with two torque modes, constant torque and linear torque, one motor and inverter set will be run as an imported generator for another controlled torque set, a torque sensor coupled to the shaft will not be used. Of the motors, since the frequency inverter itself has in its electronics a processing with high precision algorithm, capable of providing real torque information with sufficient precision só that evaluate the motor when working in the conditions of maximum use that responds to the waiting in the motor reconditioned.
