Lamination

Type of lamination

The tools available in the lamination tab allow us to define the outer shape of the lamination.

Two choices are available for defining lamination topology: Circular or Square.
Note: Lamination is available for inner rotor topology but not for outer rotor topology.

Circular shape lamination

By default, the lamination is circular. The outer diameter of the lamination is defined in the structural data of the topology in the specification of the machine.

Table 1. Slot – Lamination - Design area – Circular type lamination


1 Default setting: Lamination type is « Circular ».

Square shape lamination

  2. Definition of the slot angular shift

    With square shape lamination, it is possible to set a slot angular shift. It is advised to keep an angular shift lower than one slot pitch.

    This parameter allows adjusting the outer dimension () between the outer border of the lamination and the bottom part of the slots. For more details see the illustrations below.

Figure 1. Square shape lamination Definition of the slot angular shift = 15.0 i.e. half the value of the slot pitch.


Figure 2. Square shape lamination Definition of the slot angular shift = 0 i.e. original default value.
