Question

Among the following which one exhibits linearly rising load torque characteristics?

(a) Elevators

(b) Rolling Mills

(c) Fan load

(d) Separately excited dc generator connected to the resistive load

The question was asked in an interview for internship.

I would like to ask this question from Dynamics in division Dynamics of Electrical Drives of Electric Drives

Answer 1

Right choice is (d) Separately excited dc generator connected to the resistive load

The explanation is: Separately excited dc generator connected to the resistive load is an example of linearly rising load torque characteristics as the torque increases linearly with an increase in speed.
