What is series shunt and compound motor?
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 is DC shunt compound motor?
A dc compound motor is a combination of both dc shunt and series motors. It consists of two field windings a part connected in series and a part in parallel with the armature. It has the combined features of a dc shunt and series motors.
What is compound generator compound motor?
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 S1 S2 and shunt field coils F1 F2 connected to the armature winding as shown in the figure below.
What are the applications of DC shunt series compound motor?
Shunt DC motors are used for applications where you need constant speed, and the starting conditions are not severe. The shunt direct connection motors applications are in lathe machines, centrifugal pumps, fans, blowers, conveyors, lifts, waving machines, spinning machines, etc.
What is Series DC motor?
A series DC motor connects the armature and field windings in series with a common D.C. power source. The motor speed varies as a non-linear function of load torque and armature current; current is common to both the stator and rotor yielding current squared (I^2) behavior.
What is series motor?
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 a DC compound motor used for?
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.
Where are compound motors used?
⇒ A compound motor is used in Presses, Shears, Conveyors, Elevators, Rolling Mills, Heavy Planners, etc.
Where are DC compound motors used?
Applications of DC compound motor Compound motors due to their ability to perform better on heavy load changes are used in elevators. Due to their high starting torque and better speed control for pressure variations, they are used in shears and punches.

What is the difference between a DC compound motor and shunt?
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 type of motor is used in a shunt motor?
We carry a stock of small DC shunt wound motors in IP23 IC06 format (drip proof force ventilated). Other DC motors can be made on request. 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.
What is the series current in a short-shunt compound motor?
In short-shunt compound motor, the shunt field is connected only across the armature winding as shown below. Here, the series field current will same as the supply current i.e., I = I se, and the supply current will be the sum of the armature and shunt field currents i.e.,
What is the difference between series and compound DC motors?
Important – The compound DC machines (generator or motor), are always designed such that the magnetic flux produced by shunt field winding is greater than the flux produced by the series field winding. Applications – The differentially-compound motors are rarely used due to their poor torque characteristics.
