Winding Editor for an Adjustable-Speed Synchronous Machine

For a adjustable-speed synchronous machine, you may want to specify a different number of conductors for each stator slot. The Winding Editor makes this possible by enabling you to specify the number of turns for each coil.

To specify the number of turns for each coil:

  1. Click Machine > Winding > Edit Layout.
    The Winding Editor window appears.
  2. In the table in the upper left, set which phase you want for each coil and which slot is the “in” and “out” slot for the current in each coil.
  3. If you are working on a quarter or half model, you may want to specify a multiplier by clicking the Periodic Multiplier check box and specifying a value.
  4. Select or deselect the Constant Turns or Constant Pitch check boxes, depending on whether you want to be able to change these setting in the table above. When these options are selected, you cannot change the turns or pitch.
  5. When you are satisfied with the coil settings, click OK to close the Winding Editor window.

Defining Different Size Wires for an Adjustable Speed Synchronous Machine

Use the Gauge option in the Wire Size dialog if you have a conductor that is made up different size wires.

To define different size wires:

  1. In the Wire Size window, select MIXED from the Gauge drop-down menu.
  2. Select either Round or Rectangular as the Wire Type.
  3. Enter the appropriate wire data in the table:
    • For a round wire:
    • Enter the Diameter in the table.
    • Enter a Number in the table to specify how many of the conductor’s wires have this diameter.
    • For a rectangular wire:
    • Enter the Width of the wire in the table.
    • Enter the Thickness of the wire in the table.
    • Enter the Fillet value in the table.
    • Enter a Number in the table to specify how many of the conductor’s wires have this data.
  4. Click Add to add the new wire data.
  5. Repeat steps 3 and 4 for each size wire you want to add.
  6. When you are finished defining the wires, click OK to close the Wire Size window and return to the RMxprt Properties window.
Note: For example, if one conductor is made up of five wires, three of those wires have a diameter of 0.21 mm, and the other two have a diameter of 0.13 mm, then the mixed wire size table will have two lines. The first line will list Diameter = 0.21 and Number = 3. The second line will list Diameter = 0.13 and Number = 2. An equivalent wire diameter is displayed as Wire Size value in the Winding tab in the Properties window.
