What is an armature and how does it work?

How does an Armature Work? An armature is used as an electric motor or generator. The armature is used to communicate between two magnetic fluxes. When the armature is used as an electric motor, due to relative motion between flux produced by the field winding and the flux produced by the armature winding the EMF is induced.

The laminated silicon steel is used for the armature core to reduce the eddy current and hysteresis loss. Generally, the armature core is a hollow cylindrical shape. And the shaft is placed inside the armature core. The core consists of the number of slots.

The core consists of the number of slots. The armature winding is placed in the slots provided on the outer surface of the armature core. The slots in the armature core are skewed at some angle to avoid magnetic locking and provides smooth rotation.
