trash pump impeller

[Solved] Which of the following motors is used for centrifugal pumps?

Detailed Solution

The applications of different DC motors are:

DC shunt motor:

It is an almost constant speed motor. Hence it is used for driving constant speed line shafts, lathes, centrifugal pumps, small printing presses, paper making machines,etc.

DC series motor:

It has a very high starting torque. Hence it is used for heavy-duty applications such as electric railway, driving cranes, hoists, conveyor belts,etc.

DC compound wound motor:

It is used for driving compressors, pressure blowers, door lifts, circular saws, rolling mills, passenger elevators, etc.
