SOME COMMON PROCEDURES

  Addtional details and examples can be found in the dc-machine1.ppt power point file.

  1)   To build a 2D  model

     Alter the parameters by editing a file *.des or read in an
     existing *.des (see examples below)  file and changing the
     parameters in the  Utility>parameters>scalar


     When switching from one motor type to another, it is reccommended
     to first clear the data base.  The Toolbar will automatically be
     reinstalled.

            EXAMPLE DESIGN PARAMETER FILES:

        mach2.des       10 pole , PM on rotor, 1/5 th model
                        parallel magnization
                        (contains example winding)
                        For example loading use 10 turns, 10 amps
                        turns A phase on (the current factor to +1),
                        B phase off and reverse C phase
                        (the current factor to -1)
                        Use <PMROTOR> and <STATOR> to build the model.

        rect1.des       12 pole, PM on rotor, 1/6 th model, rectangular
                        stator slots
                        Use <PMROTOR> and <R_SLOT> to build the model.

        pms1.des        10 pole , PM  stator, 1/5 th model
                        radial magnization
                        (no winding)
                        Use <SLOT_R> and <PMSTAT> to build the model.

        radm1.des       4 pole  , PM  rotor, radial magnetization
                        (no winding)
                        Use <PMROTOR> and <STATOR> to build the model.


     Use the following toolbar items (using the  mach2.des file)

     <GET_DIMS>     Input 'mach2' in the prompt window (This loads
                    the mach2.des parameter file.

     <PMROTOR>      ( builds the PM rotor, or use the appropriate
                      Toolbar item, <SLOT_R> for a slotted rotor)

     <STATOR>       ( builds the standard stator)

     <EVEN_BC>      ( applies even periodic boundary conditions )

     <ROTATE>       ( moves the rotor for the specified mechanical degrees)

     <WIND_2D>      ( builds the data based on the winding file, when
                      prompted, enter 'mach2' which corresponds to
                      the winding file mach2.wnd)


     If the winding is defined (see example in mach2.des and the definition
     in <STATOR_H>, a load can be input with <LOAD>, which requires the
     input of the the electrical angle and the peak current.


  2)   To Solve

     <SOLUTION>     ( performs a SINGLE solution, linear or nonlinear)

  3)   To post process, the following options are available from the ToolBar

      <MACH_TOR>   Calculates the torque

      <MUR>        displays the relative permeability of the active elements, whose
                   mur > 1.5

      <B_RADIAL>   displays the B radial at the radial location in which the
                   Maxwells stress torque was calculated. <MACH_TOR> must be used first.

      <B_TANGET>   displays the B tangential at the radial location in which the
                   Maxwells stress torque was calculated. <MACH_TOR> must be used first.


      <B_VECTOR>   displays the B vector with outlines for elements with different
                   materials

      <H_VECTOR>   displays the H vector with outlines for elements with different
                   materials

      <FLUXLINE>   displays the flux lines

      <CHK_AMP>    prints a summary of the amp-turns in each of the stator slots

      <PLOTCURR>   displays the current density (Amps/m^2)
