(3) The total filed-circuit resistance, i.e., the seem to field-winding resistance and
any extra resistance connected in the field circuit is more than the critical field
resistance. In such cases, the stope field resistance time will be high and no
voltage ...
Armature Copper Loss Let the current flowing in the armature winding be
designated Ia amperes and its resistance Ru Q. Then armature copper losses = I"
aR„ watts Moreover, series field winding, interpole winding and compensating
winding ...
To enable the synchronous motor to run at the above mentioned synchronous
speed the rotor field winding is energised and at the same time brought near to
the synchronous speed, by some other means. The rotor poles, which are always
...

BASIC ELECTRICAL ENGINEERING
8.15 Compound motor made of thin wire of many turns (Fig. 8.15). The series
field winding is wound above the shunt field winding on the same pole shoe. In a
compound motor the major portion of the flux is produced by the shunt field
winding ...

Design And Testing Of Electrical Machines
The voltage across the shunt field winding is about 70% to 80% of the armature
voltage at the brushes; the rest of the voltage is absorbed in the series resistance
of the field rheostat for controlling the generator voltage or the speed of the motor
...

Control System Components
It has separately excited field winding Lf given dc voltage through a push—pull
type amplifier. The amplifier controls the direction and magnitude of the field
excitation. There is also a series field winding L1. The separately excited field
winding ...
field winding S3. This will cause the permanentmagnet rotor to once again turn in
a clockwise fashion and align itself with field winding SS. A magnetic-encoder-
type brushless DC motor is shown in Figure 17—24. Notice that this type of ...
When the armature coils carry currents they produce their own magnetic field
which interacting with the magnetic field of the field winding produces electro-
magnetic torque tending to align the two magnetic fields. The field winding and ...

4.8 TYPES OF D.C. MOTORS Like generators, there are three types of d.c.
motors characterised by the connections of field winding in relation to the
armature viz. : (/) Shunt-wound motor in which the field winding is connected in
parallel with ...
