Repairs to the electric motor rotor lead in Joule losses

When the electric motor that failed is replaced, the ideal is to be made a careful analysis to understand what the problem was presented by the electric motor. The ideal is to recover an electric motor that has low power because the cost is high and reaches the value of a new electric motor that has high performance.

In addition, when the spoiled electric motor slp-575 is recovered, new factors are introduced and this can cause the electric motor to suffer losses when compared to the original electric motor.

Repairs to the electric motor rotor with the use of machining the outer diameter that although make a small increase in the air gap, the result is a large increase in magnetizing current and the result will be losses caused in the electric motor driven by the Joule effect.
