What is a DC shunt motor?

A shunt motor (known as a shunt wound DC motor) is a type of DC motor which is self-excited and has the field windings that are connected in parallel to the armature winding of the motor. As these two parts are connected in parallel, the armature and field windings are exposed to the same supply voltage.

What is DC shunt?

What is a DC shunt? A direct current (DC) shunt is a specific type of resistor designed to send a millivolt output to a meter, or other instrument, that is in proportion to the current flowing through the shunt.

What is a shunt motor?

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. The shunt motor is configured with a stator of concentrated winding and commutator rotor as shown in the figure.

What is the principle of shunt?

A shunt motor (known as a shunt wound DC motor) is a type of DC motor which is self-excited and has the field windings that are connected in parallel to the armature winding of the motor. As these two parts are connected in parallel, the armature and field windings are exposed to the same supply voltage.

What is the theory of shunt?

Electrical measurement range is limited by the current which can be carried by the coil of the instrument safely. Hence for measurement of large current, voltage or power some means are used for increasing the range of instrument. Such mean is also called shunt.

What is the main disadvantage of a shunt motor?

As the load changes, a shunt wound motor runs at a predictable speed. If variable speed is desired, constant speed can be a disadvantage. The lifetime of the motor is usually not improved by brushes.

What are the 3 types of 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.
