Motor reaction in a generator , armature losses , hysteresis losses and field excitation
MOTOR REACTION IN A GENERATOR When a generator delivers current to a load, the armature current creates a magnetic force that opposes the rotation of the armature. This is called MOTOR REACTION. A single armature conductor is represented in figure 1-10, view A. When the conductor is stationary, no voltage is generated and no current […]

Effects of adding additional coils and poles , electromagnetic poles and armature reaction
EFFECTS OF ADDING ADDITIONAL COILS AND POLES The effects of additional coils may be illustrated by the addition of a second coil to the armature. The commutator must now be divided into four parts since there are four coil ends (see fig. 1-5).The coil is rotated in a clockwise direction from the position shown. The […]
