What is DC series wound motor?
Compound wound DC motors A hybrid between the series wound and shunt wound designs, a compound wound DC motor has a field winding that is connected in series with the armature winding and another field winding connected in parallel (shunt) with the armature winding.
What is series wound DC generator?
The 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.
What are the three types of wound DC motors?
There are 3 main types of DC motor that are available: Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.
What are series motors?
A series motor is a direct current motor that has two windings that are in series, with the same current flowing through each. Use of series motors is generally limited to cases where a heavy power demand is necessary to bring the machine up to speed, as in the case of certain elevator and hoist installations.
What is difference between shunt and series motor?
A series motor respond by decreasing its speed with small increase in current for a given load torque. A shunt motor holds its speed nearly constant with large increase in input current for same amount of load torque.
How do series wound generators work?
A series-wound generator uses very low resistance field coils, which consist of a few turns of large diameter wire. The voltage output increases as the load circuit start drawing more current. Under low-load current conditions, the current that flows in the load and through the generator is small.
What is the main disadvantage of series generator?
The main disadvantage of series generators, Output voltage varies as the load varies The e. mf induced in the armature winding is constant with . time Inter pole winding is connected in series with main poles of d.c machine Series motor maintains a more constant speed under varying load.
