How to set-up Slot Type 21?

H1 can be defined in two different way : in meter or in radian. So to set up H1 you have to use the following syntax : H1 = [value unit] with unit = 0 for m and unit = 1 for rad.

To set up a slot type 21 you need to replace the slot geometry bloc in your machine file by this code and edit it with your values :

For the stator

Input.Geometry.type_slot_shapes = 21;       

Input.Geometry.H0s = 1e-3; %[m]
Input.Geometry.H1s = [1.5e-3 0]; %[m or rad]
Input.Geometry.H2s = 30e-3; %[m]
Input.Geometry.W0s = 12e-3; %[m]
Input.Geometry.W1s = 14e-3; %[m]
Input.Geometry.W2s = 12e-3; %[m]

For the rotor

Input.Geometry.type_slot_shaper = 21;       

Input.Geometry.H0r = 1e-3; %[m]
Input.Geometry.H1r = [1.5e-3 0]; %[m or rad]
Input.Geometry.H2r = 30e-3; %[m]
Input.Geometry.W0r = 12e-3; %[m]
Input.Geometry.W1r = 14e-3; %[m]
Input.Geometry.W2r = 12e-3; %[m]

Geometrical constraints

Your slot must follow this constraint :

  • W0 <= W1
