What is mean by shunt motor?

Why it is called shunt motor?

Parallel vs series windings

In a DC shunt motor, the armature and field (shunt) windings are connected in parallel. A parallel circuit is also known as a shunt circuit; thus, the term, “shunt motor” is used.

Why shunt motors are used?

shunt motors are used wherever there is a request for stable speed. Shunt DC motors can be used in centrifugal pumps, lifts, weaving and lathe machines, blowers, fans, conveyors, spinning machines, and more.

What is the principle of shunt?

The working principle of a DC Shunt Motor is, whenever a DC motor is turned ON, then DC flows throughout the stator as well as the rotor. This current flow will generate two fields namely the pole as well as the armature.

Where is DC shunt motor used?

A DC shunt motor is used in applications where a constant speed and high torque is required, such as a paper manufacturing unit, Lathe Machines, Centrifugal Pumps, Fans, Lifts, Weaving Machine, Spinning machines, Blowers Conveyors etc.

What is the 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.

Why DC shunt motor is used in lathe?

It can be used where the speed is required to remain almost constant from no load to full load, where the load has to be driven at a number of speeds and any one of which is nearly constant. Hence DC shunt motor is used to drive the constant speed line shafting, lathes, blower and fan.

What is DC series 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 are the uses of shunt?

shunt is used to convert a galvanometer into ammeter by joined it parallel to the galvanometer. 2. Shunt can also be used in to convert galvanometer into voltmeter by joining it in series with galvanometer.

What is the role of Interpoles in DC motor?

Interpoles are designed in DC motors to overcome the effects of the armature reactance and the self-induction of the machine. Most shunt and compound DC motors over one-half horsepower have interpoles located 90 electrical degrees from the main poles.
