Which speed can be obtained from field control of DC shunt motor?

6. Which speeds can be obtained from field control of DC shunt motor? Explanation: Speeds greater than rated speeds can be obtained by lowering the flux of shunt field motor. Field cannot be made any stronger, it can only be weakened by this method.

How can the speed of a DC motor be controlled?

Thus, the speed of a DC motor can control in three ways: By varying the flux, and by varying the current through field winding. By varying the armature voltage, and the armature resistance. Through the supply voltage.

What are the advantages of DC shunt motor?

Advantages of Dc shunt motor:

The power supply of the DC motor is any way cheap. Shunt would motor able to runs at a predetermined speed. The speed of a dc shunt motor is sufficiently constant. Direct current machines can use for heavy industrial applications where the torque and speed wider range.

What are the 3 types of DC motors?

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.

What are the applications of DC motor?

DC machines are also used in applications where high starting torque and accurate speed control over a wide range are important. Major applications for DC motors are: elevators, steel mills, rolling mills, locomotives, and excavators. Like other rotating machines, DC motors result from the interaction of two magnets.
