Question

what are the characteristic of a series motors​

Answer 1

Answer:

N/Ta Characteristic (Mechanical)

It is found from above that when speed is high, torque is low and vice-versa. It is clear that series motor develops high torque at low speed and vice-versa.

Answer 2

$\large\mathbb \blue{\fcolorbox{blue}{black} { \ VERIFIED\ ANSWER \ }}$

DC series motors are always connected to loads by gears so that minimum load is always maintained to keep the speed with in safe limits. Since a series motor develops high starting torques at low speeds and low torque at high speeds, therefore, speed – torque characteristics of a DC series motor is a hyperbola.
