Dc Motor Labeled Diagram. This rotor is inside a stator or a stationary housing that contains a permanent magnetic field generated by either a magnetic metal or some type of electromagnet shown in figure 1 as the coil labeled. In fact the same dc machine can be used interchangeably as a generator or as a motor.
The huge current can be carried by field windings because these windings have few turns as. When an electric current is passed through the coil as shown in the diagram equal and opposite forces act on opposite arms of the coil due to which the. The armature is placed in between north pole and south pole of a permanent or an electromagnet as shown in the diagram above.
In this motor field as well as stator windings are coupled in series by each other.
Figure 3 diagrams of the various types of dc motor parallel excitation separate or shunt the coils armature and field coil are connected in parallel or supplied via two sources with different voltages in order to adapt to the characteristics of the machine e g. Figure 3 diagrams of the various types of dc motor parallel excitation separate or shunt the coils armature and field coil are connected in parallel or supplied via two sources with different voltages in order to adapt to the characteristics of the machine e g. The very basic construction of a dc motor contains a current carrying armature connected to the supply end through commutator segments and brushes. As shown above dc motors are powered by a dc power supply connected to the rotor assembly via carbon brushes.
