Generally a servomotor operates at
-
If C is thermal capacitance, m is mass of liquid and c is specific heat, then
-
Assertion (A): The concept of impulse function is useful in differentiating discontinuous functions.
Reason (R):
-
In a two phase servomotor, if R is rotor resistance, X is rotor reactance, L is rotor length D is rotor diameter then
-
The ac motor used in servo applications is
-
A first-order system has a time constant t. For unit ramp input, the steady state error is
-
The system in the given figure is
-
For the equation
where Q is heat energy, Ct is thermal capacitance and θ is temperature, the analogous electrical equation is
where a < 1, gives maximum phase lead at a frequency equal to
