what are classification of DC M/c ? 15. speed torque characteristic of all type of DC M/c ?

Question

Accepted Answer

DC machines can be classified into two types: DC motors and DC generators. The speed-torque characteristic of DC machines varies based on their type and construction.

DC motors can be classified into shunt, series, and compound motors
DC generators can be classified into separately excited, shunt, series, and compound generators
Shunt motors have a nearly constant speed-torque characteristic
Series motors have a high starting torque and variable speed-torque characteristic
Compound motors have a combination of shunt and series characteristics
Separately excited generators have a nearly constant voltage output
Shunt generators have a nearly constant voltage output
Series generators have a variable voltage output
Compound generators have a combination of shunt and series characteristics
