TYPES OF DC MOTORS
There are various types of DC motors found in industry today. Each type
contains various characteristics that makes it desirable for certain applications.
EO 1.8
DESCRIBE the differences in construction between a
shunt-wound and a series-wound DC motor with respect
to the relationship between the field and the armature
windings.
EO 1.9
DESCRIBE the construction of a compounded DC
motor.
EO 1.10
DESCRIBE the torque-vs-speed characteristics for a
shunt-wound and a series-wound DC motor.
DC Motor Connections
Figure 7 shows schematic-
Figure 7 DC Motor Connections
ally the different methods
of connecting the field and
armature circuits in a DC
motor.
The
circular
symbol
represents
the
armature circuit, and the
squares at the side of the
circle represent the brush
commutator system. The
direction of the arrows
indicates the direction of
the magnetic fields.
