ABB Magnet Motor Repair

Our Montgomery Service Center recently test ran a spare ABB Permanent Magnet motor for a large paper company. As an ABB AVP service provider Jay Montgomery and Birmingham centers have the trained knowledge, Variable Frequency Drives and equipment to service these unique AC machines. This machine will go into service soon and its sister will come out for a possible rotor replacement.

This machine is a ABB AMZ, 420kw, 205 RPM running at 17.08Hz. These synchronous machines are becoming very popular in all industries due to their ability to operate at low synchronized speeds without the need for gearboxes and other speed reducers.

Ultrasonic cleaning System

Jay Industrial Repair has processed their first rotor in our new ultrasonic cleaning tank and highlighted below are some before and after pictures. We are really pleased with performance and it will only improve as we get more familiar with system and how to get most beneficial results.

Below are pictures of a 700hp AC rotor we cleaned using the Ultra Sonic for the 1st time. We had a similar rotor in this condition a couple months ago. Using the steam cleaner we had to go back 3 different times before we got it clean enough to do a core loss/rotor bar test on it.

This rotor was in the tank 20 minutes at 160 degrees, hosed off the residue and after its dry it will be ready to test and install.

The first picture is off the rotor before in condition it arrived. The 2nd picture is the rotor submerged in the ultrasonic tank and the final two picture are after being in tank for 20 minutes.
