i) The linear relationship in between electrical control signal and the rotor speed over a wide range.
ii) The inertia of rotor should be as low as possible.
iii) A servo motor must stop running without any time delay, if control signal is removed.
iv) For low inertia, it is designed with large length to diameter ratio for rotors, compared to its frame size. The rotor of servomotor has very small diameter.
v) It's response should be as fast as possible, for quickly changing error signal, it must react with good response. This is attain by keeping torque to weight ratio high.
vi) It should be easily reversible.
vii) It should have linear torque speed channel.
viii) It's operation should be stable without any oscillation or overshoot.
