Is it possible for an armature to be damaged?
And we never want to have continuity between any of the bars and ground. It’s always supposed to be open circuit. If your measurements fail any of these, it’s very possible the armature has broken or damaged windings and will not function properly.
How can I check the armature of my commutator?
However, if the motor design has external brush holders, you can unscrew the brush caps and remove the brushes. Depending upon brush size, this may allow access to the commutator without removing the armature from the motor. The first check to see if your armature windings are shorted is the “180° Resistance” test.
How can I tell if my armature windings are short?
The first check to see if your armature windings are shorted is the “180° Resistance” test. A volt/ohm meter can be used to check the resistance of the series windings connected between the two commutator bars of each coil.
Which is the last test to check for armature damage?
Now, you may not know what your armature design is going to read. Again, it’s just important that they do not vary radically. The last test is the bar-to-ground test. In this test we’re measuring the resistance of every bar to ground, in this case the armature shaft.
How are the bars connected to the armature?
On this armature, we have a shaft and a commutator, which has bars. The commutator bars are connected to the armature winding and the winding is wound around the teeth on the lamination stack. This creates an electromagnetic effect, which interacts with the permanent magnets in the motor housing, causing the motor to turn.
How are the windings on an armature measured?
For today’s Tech Tip, we’re going to cover how to measure an armature for broken or damaged windings. On this armature, we have a shaft and a commutator, which has bars. The commutator bars are connected to the armature winding and the winding is wound around the teeth on the lamination stack.

Here are three quick checks you can perform with a volt/ohm meter to test a DC motor armature winding to determine if a motor armature is functioning properly. Hi I’m Jim.
What to do if rigging model won’t follow armature?
What you must do is parent against the rigify armature with Automatic Weights (or empty groups), and then do the weight painting process. Highly active question. Earn 10 reputation (not counting the association bonus) in order to answer this question.
Can a fractional horsepower motor have a damaged armature?
It’s always supposed to be open circuit. If your measurements fail any of these, it’s very possible the armature has broken or damaged windings and will not function properly.
