Motor speed is controlled by varying the current in the field windings.for example,when the amount of current flowing through the field windings is increased, the field strength increases, causing the armature wingdings to produce a larger counter EMF which slows the motor.conversely,when the field current is decreased, the field strength decreases, and the motor speeds up because the conter EMF is reduced.

调速控制的不同目前在外地windings.for例如，当电流流动量的通过外地绕组是增加，电场强度的增加，导致电枢wingdings产生较大的反电势而减慢motor.conversely当外地电流降低，电场强度降低，电机的速度，因为conter电磁场降低。
