  Right Hand Rule of Fleming

Introduction to Right Hand Rule of Fleming

Find out the current direction through applying right hand rule of Fleming, while the mode of operation is a generator and left hand rule of Fleming, while the mode of operation is a motor. Or the current direction to all coil sides may be arbitrarily supposed.  Mark downward current direction for the coil sides within the North Pole regions and upward current direction within South Pole regions, as displayed in the above diagram.

To set the brush arm positions and to find the no. of parallel paths offered through the armature winding, commutator ring diagram is employed, as shown in the diagram below.

Diagram - Commutator ring diagram

Draw the vertical solid lines equivalent to number of coil sides and join them with reference to Table (Winding table for 2 pole, 6 slot simplex lap winding), as displayed in the above diagram.  As well mark the current direction by the coil sides with reference to main winding diagram in the above diagram.

Look for adjacent pair of coil sides comprising similar current direction. For coil sides 12 and 7 carry that carry upward currents, mark negative brush arm, and for coil sides 6 and 1 carry that carry downward currents, mark positive brush arm, as displayed in the above diagram. Brush arms should be equivalent to the number of poles.

Now, transfer the brush arms to the main winding diagram in the diagram (Main winding diagram). Mark positive brush arm under the commutator segment 1, in which the coil sides 1 and 6 meet.  Likewise, mark negative brush arm under the commutator segment 4, in which the coil sides 2 and 12 meet. Tap out two leads and mark AA for negative brush arm and A for positive brush arms.  These two leads now point out the dc machine's armature terminals.

To decide the no. of parallel paths offered through the lap winding, redraw the above figure as displayed in the below diagram.

Diagram - Parallel paths for 2 poles 6 slot simplex lap winding

According to the above diagram, it can be seen that the number of parallel paths in a lap winding, will be equivalent to number of poles.         

Equation: A = P

In which,  A stands for = number of parallel paths;       

P stands for = number of poles

The current by each armature coil or conductor will be the ratio of the total armature current through the number of parallel paths, that is,

Equation: I = IA / A

In which I stands for = current through each armature conductor/coil;

IA stands for= total armature current
