5. Uses of DC motor
Definition : 5.1. Independent excitation
This engine is characterized by a constant speed. It is most often used in independent excitation, with speed regulation.
Definition : 5.2. Serial excitation motor
This engine has a very high starting torque, it is suitable for all electric traction applications, however, it presents risks of runaway empty.
A-Series connection A series DC motor connects the armature and field windings in series with a common D.C. power source. A series motor should never be started at no load. Series motors called universal motors can be used on alternating current. B-Shunt connection A shunt DC motor connects the armature and field windings in parallel or shunt with a common D.C. power source. T C-Compound connection A compound DC motor connects the armature and fields windings in a shunt and a series combination to give it characteristics of both a shunt and a series DC motor.A- |  |
