Damage to the armature winding;
Presence of short circuit in turns;
Breaking resistance between the core and the winding.
Such faults can be identified using special measuring instruments, such as a multimeter.

Checking the anchor with a multimeter
To perform such a test, you need to disassemble the angle grinder and gain access to the anchor. The multimeter needs to be set to the 200 Ohm range, and the probes of the device need to touch two adjacent lamellas.
