Armature Core Analyzer

Why Use The Armature Core Analyzer Before Rewinding?

1    With all the different laminations being used in imported armature today, no one knows the
percentage of efficiency the laminations have.  With the Armature Core Analyzer the unknown is eliminated allowing a much higher salvage rate and stopping the use of cores that will fail, BEFORE THEY ARE WOUND.
2    Armatures that are burned out in excess of 750 degrees Fahrenheit loose their magnetic efficiency causing higher amps and lower torque.  Armature Core Analyzing will eliminate these unknowns.
3    Armatures that have variations in the lamination OD’s can produce lower torque and higher amps.  Armature Core Analyzing will also eliminate this unknown.

This test will allow you to compare your lamination stack and shaft assemblies’ steel magnetic capabilites to OEM material or to your own “in house” generated standard.  This tester is designed to give you a constant source of equal magnetic strength lamination stacks and shafts, so that you will know the torque of the armature before you waste the time and money winding an armature that will not pass your final load test for high amps and/or low torque.

PRODUCTION ARMATURE COMPARITOR

BASIC THEORY
The Armature Comparator is designed to test armatures by comparing them to an OEM or known good armature.  By comparing to the “Known Good Armature”, you can check torque as well find shorts, bad connections, opens, and leakage to ground.   The Oscilloscope allows you to find out what is wrong with the armature i.e.:  shorts, opens, bad connections and leakage to ground.  The Analog Meter allows you to set the electronic circuits and to read torque after the machine is set.  The Analog Meter will also read the approximate resistance of the leakage to ground in ohms. 

There are two types of windings used in automotive armatures, LAP & Wave. The Armature Comparator will locate faults in both types of windings.  Lap Windings are wound using parallel windings.  The individual coils are connected to the commutator bars which are adjacent or close to each other.  The Wave Windings use a series of windings and the individual coils are connected to the commutator bars which are approximately two pole pitches apart.  What this means to you is that you will be able to locate problems in an armature before it is put in a unit and read the armature torque.

TORQUE.......Why look for it?  Because an armature will loose torque if any or all of the following conditions exist.

•    Non-OEM lamination steel
•    Small wire size or lower grade copper used in the hairpins
•    Laminations being burned to hot, before being rewound
•    Not enough laminations
•    Improper twist of the hairpins during winding or rewinding, (improper
    commutation).
•    Relocation of the hairpins when the commutator is replaced, (changing
    commutation).

It has been found that most low strength (Torque) armatures have a combination of the above deficiencies in them.
