Un-Bifurcated Three Phase Concentric Winding

UN-BIFURCATED THREE PHASE CONCENTRIC WINDING

AIM:

To draw concentric un- bifurbcated winding diagram with two planes over hang, for a three phase, 48 slots, 8 poles AC armature.

PROCEDURE:

Step 1: Set the limits of the drawing screen.

Step 2: Put ORTHO ON where as necessasary.

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 conductor.

Step 6: Use pline command for making arrows.

Step 7: Make the numbers on the conductors using TEXT command.

Step 8: Use DONOT Command wherever need.

Step 9: Use copy, layer commands.

Step 10: Commands: q save.

Solution:

Slots/pole/phase = 48/(8 x 3)  =  2

Thus one pole phase group consists of two slots.

Coil span = pole pitch = slots per pole = 48/8 =6

Angle between consecutive slots = 180^o /6 =30^o electrical

RESULT:

         Concentric winding un- bifurcated diagram with two plane over hang, for a three phase, 48 slots, 8 poles AC armature is drawn by using AutoCAD software.
