compound-wound in American English (ˈkɑmpaundˈwaund) adjective. Electricity. noting an electric device in which part of the field circuit is in parallel with the armature circuit and part is in series with it.
How does a compound wound motor work?
With a DC compound motor, the majority of the field is wound for a shunt field but with a few turns of series winding on top. The shunt is connected across the field supply and the series turns are connected in series with the armature. This provides a motor with a combination of the shunt and series characteristics.
What are types of compound motor?
The types of compound excited DC motor are Short Shunt Motor, Long Shunt Motor, Differential Compound, Cumulative Compound.
What is a compound DC motor used for?
Applications. Cumulative compound wound motors are virtually suitable for almost all applications like business machines, machine tools, agitators and mixers etc. Compound motors are used to drive loads such as shears, presses and reciprocating machines.
What is the compound motor and connection?
Definition. Compound DC motor is a compound of both series and shunt motor. It is consist of a Series field coil, which is connected in series with the armature field winding, and a shunt field coil winding, which is connected in parallel with the armature field winding.
What is a commutator in a motor?
The commutator assures that the current from the generator always flows in one direction. On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.
What is meant by compound motor?
As we mentioned before, compound DC motors are basically made up of a combination of series and shunt motors. they are also called DC compound motors. this type of motor has both series and shunt field coils that are connected to the winding of an armature.
What is the advantage of a compound motor over a shunt motor?
More flux will mean more torque and reduced speed as compared to the shunt DC motor. A compound motor can also be run at no load, and it will not be destroyed due to very high speed as the case present in the series motor. The compound motor has a specific no-load speed.
What is meant by Compound motor?
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.
What is shunt wound motor?
shunt-wound in Electrical Engineering A shunt-wound motor or generator has the field and armature circuits connected in parallel. Current in the field windings of a shunt-wound generator is independent of the load current, because currents in parallel branches are independent of each other.
What is meant by series wound and shunt wound?
If a motor or generator is series-wound, it has the field and armature circuits connected in series. Related wordsCompare series-wound with shunt-wound in which the motor or generator has the field and armature circuits connected in parallel. COBUILD Key Words for Electrical Engineering.
What does motor, compound or compound wound mean?
A compound wound DC motor (also known as a DC compound motor) is a type of self-excited motor , and is made up of both series the field coils S 1 S 2 and shunt field coils F 1 F 2 connected to the armature winding as shown in the figure below.
What is compound wound generator?
A generator with such a double-field winding is called a compound-wound generator. When the series winding is connected to aid the shunt winding, the generator is called a cumulative compound-wound generator; if the series winding is connected to oppose the magnetic field, it’s called a differential compound-wound generator.
What is a DC series wound motor?
Series Wound DC Motor or DC Series Motor. A series wound DC motor like in the case of shunt wound DC motor or compound wound DC motor falls under the category of self-excited DC motors, and it gets its name from the fact that the field winding in this case is connected internally in series to the armature winding.
What are the applications of DC compound motors?
In Elevators due to the ability of the compound motor to perform better on heavy load changes.
