DOCUMENTATION FOR THE SLOTTED STATOR PARAMETRIC MODEL
<STATOR_H>
All parameters are to be contained in a single file whose filename
has the extention "des". (e.g., mach1.des) The first part of the
filename is the item entered in the ANSYS Input window when "GET_DIMS" is
selected from the Toolbar. When entering this filename, the characters
must be enclosed in single quotes ( e.g. 'mach1' for the
parameter file "mach1.des" ). These parameters can be combined into
a single file with the parameters for the rotor.
1) The geometry parameters related to the dimensions of the stator
are contained the plot file "stator.doc". These plots can
be accessed by the DISPLAY program using the file "stator.doc".
2) The parameter file can also contain the material properties:
Air Material Number 1
Stator iron Material Number 5
Stator conductor Material Number 6
If the parameter file contains material properties, enter into
the Preprocessor before selecting {GET_DIMS} from the Toolbar.
The following additional distinction for the air elements in the air
gap has been made:
Air on the rotor side of the air gap: REAL SET 5
Air on the stator side of the air gap: REAL SET 6
3) The remaining scalar parameters are defined below:
stat_id='slotsta' The stator model type identifier. (This prevent
other model macros from using the data for the
slotted stator.)
npole = number of poles contained in the complete machine
nsp = number of stator teeth
ncons = number of phases per slot (maximum of 2)
nspgen= number of stator teeth to be generated
ggeom = the length conversion factor from the units of the
parameters to meters (for English to MKS, ggeom=.0254)
stkthk= length of stack (used in computing the torque)
stref = level of mesh refinement for the stator
(1 for least refinement, 5 for greatest refinement)
mname = identification to be printed out in summaries
Parameters used if the ToolBar is used to build the model:
USE_53=0, use plane13 elements, =1, use plane53 elements
F_MESH=mesh control at the back iron, F_MESH=1 least control, F_MESH=4, the mesh
in the backiron is coarse
NOTE:
NOTE:
At the completion of the stator generation, the stator elements and
nodes are contained in the component group "STATOR". This identification
is necessary for the other Toolbar items to function.
The coil elements are contained in the element component "S_COIL". This
is required for the coil to be loaded with the Toolbar.
DEFINITION OF THE WINDING FILE:
The winding file specifies the in-out slots for each coil for which a current
will be applied using <load>, or during the other macros which generates multiple
solutions.
There must be an entry made for each coil to be simulated in the model.
The format is defined below. The out slot indicates that + current (for electrical angle
0 to 90) flows in the +Z direction).
There are no limitations on the number of phases. A maximum of two coils may be
placed in a single slot.
