are placed in these slots and fastened by steel wires to keep them in position. Each armature slot is partitioned into two layers, a top layer and a bottom layer. The winding is called as a double layer winding.

The winding is called as a double layer winding. Institute Technology DC” - MIT OpenCourseWare 1.2 T, air-gap working flux densities can be on the order of 1 T. With the requirement for slots to carry the armature current, this may be a practical limit for air-gap flux density anyway. It is also important to note that the magnets in this design are really in the “air gap” of 2 universal motor construction and working principle ... The rotary armature is of wound type having straight or skewed slots and commutator with brushes resting on it. The commutation on AC is poorer than that for DC. because of the current induced in the armature coils. For that reason brushes used are having high resistance.
