REPAIRS OF HIGH POWER INDUCTION MOTORS

High power induction motor is an repairable object. During its life time the  stator winding,  bearings, ventilator and even whole rotor core with squirrel cage can be exchanged. The motor in repair process can be redesigned, its operating characteristics (esp. efficiency factor, noise level, starting capacity) can be improved.
Several methods for improving induction motors performance at the  repair process were elaborated by KOMEL Centre, Katowice, Poland. Most important of them concern enlargement of starting capacity and lowering the noise level of high voltage, high power induction motors.  

Adjustment the starting capacity of the motor to the starting and exploitation condition of the driven machinery prolongs  the motor life  and makes the whole driving set highly reliable and durable.

In the following table several examples of redesigned motors with exchanged rotor cores with  new, special rotor squirrel cages (some of them patented) are listed here. 

In every case  very  high durability of the motor was reached.
