Commutator testing
Set the meter to measure resistance (Ohms) and then measure the resistance from two commutator bars 180° across from each other. Rotate the armature and check the resistance between every pair of bars on the commutator. Figure 3 depicts a 32 bar commutator, so this check must be done between each … See more An armature (pictured on right) has a continuous series of windings from each bar on the commutator, which loop around the iron stack teeth … See more To check the condition of the armature windings, the armature will probably have to be removed from the motor. However, if the motor design has external brush holders, you can … See more The third and final test is to measure the resistance of every commutator bar to the iron armature stack. If the motor armature stack is directly pressed onto the armature shaft, you can use … See more The second check is the “Bar to Bar Resistance” test (pictured on right). This will check every coil in the motor armature. Again, the specific … See more WebCovering the theory, application, and testing of contact materials, Electrical Contacts: Principles and Applications, Second Edition introduces a thorough discussion on making electric contact and contact ... defined commutator from the perspective of abstract algebraic logic.
