DC Wave Winding

DC  WAVE  WINDING

AIM:

Design and draw a developed DC simple wave winding diagram for a DC Machine having 4 poles, 34 armature conductors using Auto cad software.

PROCEDURE:

         The following general commands are used to draw the developed DC lap winding diagram using Auto cad.

Step 1: Set the limits of the drawing screen.

Step 2: PUT ORTHOON where ever necessary.

Step 3: Using OSNAP function.

Step 4: Draw conductors of appropriate dimension using LINE Command

Step 5: Use rectangular Array Command for making rows and columns of conductors

Step 6: Use p-line command for making arrows.

Step 7: Use Rectangular command for making poles.

Step 8: Make the numbers on the conductors using TEXT Command.

Step 9: Use Copy, Hatch, Donut, Arc Commands.

Step 10: Command: – q Save.

Solution:

y_b  and y_f  can be calculated by using the following formulae.

                   ( y_b + y_f ) / 2 = ( Z ± 2)/P

                  ( y_b + y_f ) / 2= (34+2)/4  (for progressive winding)

                  y_b = 9    y_f = 9

RESULT:

                  The DC wave winding is drawn by using AutoCAD software.
