3. Servo motor
servo motor is a rotary actuator or linear actuator that allows for
precise control of angular or linear position, velocity and acceleration,
and can be controlled in terms of speed and turning angle

5. servo motor: Motion control system

6. Servo motor advantages and
disadvantages
Advantage
 High output power relative to
motor size and power
 Encoder
 Resonance and vibration free
operation
 High efficiency
 There is no out-of-step condition,
as heavy load placed on the motor
the driver will increase the current
to the motor
 High speed operation is possible
Disadvantage
 Require tuning to stabilize
feedback loop
 Complex, require encoder
 Poor motor cooling
 Motor can be damaged by
sustained overload.

7. What is encoder?

8. Servo motor Applications
5 examples

9. Solar Tracking System
Servo motors adjust the angle of solar panels throughout the day so that each
panel continues to face the sun, harnessing maximum energy from sunup to
sundown.

10. Metal Cutting & Metal Forming Machines
Servo motors provide precise motion control for milling machines, lathes,
grinding, centering, punching, pressing, and bending in metal fabrication

11. Antenna Positioning
Servo motors are used on both the azimuth and elevation drive axis of antennas
and telescopes

12. Automation factories
(cutting , grapping, moving the parts)

13. automatic Door Openers
Supermarkets and hospital entrances are controlled by servo motor

14. operation for servo motor

15. How to shows the correct size of the
servo motor?
First of all we need to know that is inertia?
Inertia is the resistance of any physical object to any change in its velocity

16. How to shows the correct size of the
servo motor?
Know for selecting servomotor the following must be considered
 Performance of the motor improves as the inertia ratio decreases
 Control loop tuning and machine performance improves as the inertia ratio
decreases
 A motor with too low of an inertia ratio will be more expensive and have little
to no performance improvement
 System inertia ratios should be designed for a max of 10:1 but are typically
5:1 for ideal performance
 When choosing and calculating an inertia ratio, find the smallest motor that
has the ability to provide the speed and torque necessary for your
application.
