DC motor :

-DC (Direct Current) Motors are two wire (power & ground), continuous rotation motors.

-The speed of DC motors is controlled using pulse width modulation (PWM), a technique of rapidly pulsing the power on and off. The percentage of time spent cycling the on/off ratio determines the speed of the motor, e.g. if the power is cycled at 50% (half on, half off), then the motor will spin at half the speed of 100% (fully on). Each pulse is so rapid that the motor appears to be continuously spinning with no stuttering.

Servo Motor :

-Servo motors are generally an assembly of four things: a DC motor, a gearing set, a control circuit and a position-sensor (usually a potentiometer).

-The position of servo motors can be controlled more precisely than those of standard DC motors, and they usually have three wires (power, ground &). Power to servo motors is constantly applied, with the servo control circuit regulating the draw to drive the motor.

-PWM is used for the control signal of servo motors. However, unlike DC motors it's the duration of the positive pulse that determines the position, rather than speed, of the servo shaft.

Does the servo motor contain the servo?

A "servo motor" and a "servo" are the same thing. Servos are constructed from three basic pieces; a motor, a potentiometer (variable resister) that is connected to the output shaft, and a control board. The potentiometer allows the control circuitry to monitor the current angle of the servo motor. The motor, through a series of gears, turns the output shaft and the potentiometer simultaneously. The potentiometer is fed into the servo control circuit and when the control circuit detects that the position is correct, it stops the motor. If the control circuit detects that the angle is not correct, it will turn the motor the correct direction until the angle is correct. Normally a servo is used to control an angular motion of between 0 and 180 degrees. It is not mechanically capable (unless modified) of turning any farther due to the mechanical stop build on to the main output gear.


What is the function of a servo motor?

A servo motor is an electric motor with a built in rotation sensor, they are needed for robotics. Say a robot moves its arm by turning a servo motor, the motor would send information concerning the degree of rotation on its axis back to the robot so the robot can keep tabs on the position of its arm, so if something bumps its arm it will know it and so-on.

Does syringe pump uses servo motor or stepper motor?

Syringe pumps can utilize both servo motors and stepper motors. However, I am satisfied with the IPS syringe pump model IPS-14RS, which are equipped with stepper motors. The model allows infusion, withdraw, and saving and recalling functions.

What is the main difference between dc motor and dc servo motor?

A DC motor is an electric motor that turns on the application of a DC current. A DC Servo motor is similar but it produces a DC current from a mechanic movement of the armateur or may also produce small movement from the application of low current.. An example of a servo motor is as was used in steering gears and auto pilots. The physical turning of the wheel either caused a current to flow or caused an inbalance in the electrical systems, this causes a counter action to restore the original position.

Difference between servo valve proportional valve?

What is the difference between servo valves and proportional valvesThere are no strict rules between Servo valves and proportional valves, because the proportional valve"s performance is getting better, gradually close to the servo valve, so in recent years there has been proportional servo valve. The difference between servo and proportional valve can be divided into the following points: 1. Drive different.2. Different performance parameters.3. Different valve structure and precision.4. Function in different types.5. Valve rated pressure drop are different.So people can choose the different kinds of valves on the basic of you require.Angad kumar pandey
