Powerbilt Armature for Powerbilt Angle Grinder PBT-AG4-1100

The armature is a critical component of the angle grinder. It is responsible for generating the rotary motion that powers the grinding disc. The armature consists of a magnetic core and copper windings that surround it. When an electric current passes through the windings, it creates a magnetic field that interacts with the field created by the permanent magnets in the motor housing, causing the armature to rotate.
