A shunt motor is a “winding-field DC motor” that generates magnetic field flux using electromagnets. Its field winding and armature winding are connected in parallel. … A feature of this motor is that the rotating speed does not change significantly if the load (on the motor shaft) varies.
What are shunt motors used for?
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 are series and shunt motors?
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 do you mean by shunt?
to shove or turn (someone or something) aside or out of the way. to sidetrack; get rid of. Electricity. to divert (a part of a current) by connecting a circuit element in parallel with another. to place or furnish with a shunt.
What are the two main characteristics of a shunt connected motor?
Characteristics of a DC Shunt Motor:
- Speed-Armature Current Characteristic: …
- Torque-Armature Current Characteristic: …
- Speed-Torque Characteristic: …
- Break in Field Circuit of a DC Motor:
Which motor is constant speed?
A DC motor can be referred to as a constant speed motor because it can self- regulate its speed.
How does a shunt DC motor work?
A shunt DC motor has a feedback mechanism that controls its speed. As the armature rotates in a magnetic field, it induces electricity. This EMF is generated in a reverse direction, thus limiting the armature current. So the current through the armature is decreased and speed of the motor is self-regulated.
