mibawadHello,
What do you mean by drooping curve? Could you explain more?
Best wishes,
Mohammed 
narayana murthyits difficult to explain i think i can find a image of it
here it is but the curve dont bend completely changes on end refer books for more information 
mibawadAll textbooks refer to the speedtorque curve for permanent magnet DC motor as a line in first quadrant as in the figure
I am asking about what about the curve in Q.2, Q.3, and Q.4?
Thanks

same there will be no change on quarents but as i know that motor is a special type motor in many of cases DC motor means we take electromagnet type DC motor as ideal speed is constant for any load for DC motor but i dont know about these charectersticsmibawadAll textbooks refer to the speedtorque curve for permanent magnet DC motor as a line in first quadrant as in the figure
