WebSeries Wound Motors In a series DC motor, the field coils and armature windings are connected in series. The field winding in the series wound motors receive more current than any other type of DC motor. And they have the highest starting torque with the most excellent no-load speed. WebThe series-wound generator is used principally to supply a constant current at variable voltage. If a motor or generator is series-wound, it has the field and armature circuits connected in series. Related words Compare series-wound with shunt-wound in which the motor or generator has the field and armature circuits connected in parallel.
WebA Series-Wound Motor in Operation The total resistance (Rf +Ra) ( R f + R a) of a series-wound dc motor is 2.0Ω 2.0 Ω ( Figure 13.33 ). When connected to a 120-V source ( ϵS ϵ S ), the motor draws 10 A while running at constant angular velocity. (a) What is the back emf induced in the rotating coil, ϵi? ϵ i?
