Servomotor's are not used in common household machinery very often. They are used in robotics and more extensively in CNC machine tools. One can find more details about them on wikipedia.
With a DC motor, power is supplied from a controller and transmitted to the motor windings via brushes and a commutator using pulse width modulation. This requires that the controller be adequate to handle the power/heat of the application and that the brushes and commutator are well maintained as they are wearing parts. With an AC servomotor, the controller only provides a low power signal to any size motor. Raw power to the motor is handled separately from the control circuit. The control signal is used to control the position of the motor which has internal position sensing capability. Power to the AC servo is always on.

You can modify the velocity of a servomotor continuously by adjusting the pulse width modulation (PWM) signal sent to the motor driver. By changing the duty cycle of the PWM signal, you can control the average voltage supplied to the motor and thus adjust its speed dynamically. You can also use feedback mechanisms, such as encoders or sensors, to precisely adjust the motor velocity in real-time.

AC servomotors require an alternating current as a power source, meaning they need to be plugged into an outlet, while DC servomotors require a direct current as a power source, meaning they can be run off of battery power.
what year is the car? it possibly could be that the choke is not disengaging after the car has warmed up. If the car has an automatic choke (powered by an electronic servomotor), that motor may have broke and left the choke on allowing the car to run when cold but not when hot. Other than the choke, your idle speed may be way too low, so check timing and fuel injection/carburetor tuning. If none of that seems to help check the ignition and make sure the plugs look good, sometimes bad plugs don't work if there isn't plenty of fuel. hope this helps...
Servomechanism is the combination of set of devices using for precision activities like movement, triggering, aiming by acting in a closed loop system by comprising an input device, a processor, a module to analyse feedback, prime mover like servomotor, a sensor for giving feedback. In each incremental motion a position feedback is sent to processor to analyse to deliver an instruction to module such that position value - feedback incremental value is the current position which will loop until target value become null.
They got their education by secretly learning it if their master didn't allowed because it was illegal. Sometimes, their masters tought the slave even though it was against the law. By secretly learning it, they could learn it off another slave or steal a book and educate themselves.
A servomotor is used within a position-control or speed-control feedback control system. Servomotors are used in applications such as machine tools, pen plotters, and other control systems.An electrostatic motor is based on the attraction and repulsion of electric chargeA Torquemotor (also known as a limited torque motor) is a specialized form of Induction_motorwhich is capable of operating indefinitely while Stall_(engine), that is, with the Rotor_(electric) blocked from turning, without incurring damagePlz read these sentencesEng.Irfan ullah PAk03009142027
