s not directly aiiect the amountof magnetic f^ux which passes through the armature. Inthe series motor, however, the amount of current passingthrough the field coil is directly proportional to the load onthe motor. Since in a general way the amount of magnetic(lux through the armature is… … Figure 50Diagram of connections of series motor. Another thing which causes the speed to drop is thevoltage lost in the resistance of the field coil and armature.Due to these two causes the speed of the series motor isexceedingly variable, being high when the load is light andthe magnetic flux is…
