In this lesson, we will continue the discussion on the topic of motion control.
All of us at RealPars, hope you have been following our previous lessons on motion control and have begun to benefit from these lessons.
Now that we have learned about motion control motors, we can begin to explore some advantages and disadvantages when selecting, primarily between, the Servo Motor and Stepper Motor.
In this lesson, we discuss Servo Motor Advantages and Disadvantages when compared to Stepper Motors.

Informative video!
tks for information
Thanks for the valuable information
You are very welcome Ramesh! Happy learning.
gained good knowledge about servo motors..
Great to hear! Happy learning!
I thank you so much for these wonderful videos, now i know i need to start from Stepper motor since i am a noob.
Man what a lot of nice information.
Great to hear that! Thanks for sharing your support!
@@realpars Hi real pars, nowadays i'm getting confused because there are stepper motors with encoder built in or feedback, and that makes them closed loop, so how does it fare with servo with feedback other than the speed-torque ratio? and can't stepper use PID control?
And also hobby servo motors have potentiometer built in, but that doesn't make them close loop or it can't tell me it's position, so where does the difference between professional servo motor and hobby servo motor lies? Hobby servos makes me crazy, so many questions.
Sorry for such a simple question on a professional channel
Very informative well presented
Thank you!

Really good video, thanks
Thank you! Happy to hear.
Excellent presentation with clear animations, thanks for this.
Thanks for your comment and support, Peter!
this video help me to choose a good cnc router
really appreciated.
Great to hear that!
Thank you
You're welcome!
Thank you very much gentelmen.
Our pleasure!
Thak you guys cool video
Thank you 😀✌
You're very welcome, Pritesh!
Great Videos-awesome
Thanks a lot, Adel!
Thank you very much !
Our pleasure! Happy learning
good video, I learned a lot. an you compare servo motors to nybrid stepper motors (closed loop)?
Happy to hear that, Steve! I will forward your topic suggestion to our course developers!
Thanks for sharing and happy learning.
Please upload video about positioning control of stepper motor using PLC &SCADA
I will pass your request on to our creator's team.
nice vid
Thanks a lot!
Thank you for your videos, I love your channel, by the way, I have two questions. Can you please make a video about SERVO-PROGRAMER SALARY? and please, can you talk about the new OFFLINE PROGRAMMING ROBOTIC ARMS? like ROBO-DK for example, hope you can help me. Your videos are great.¡¡
Thanks for your support! Great topic suggestions, I will happily pass that on to our course developers.
Happy learning!

You can use an encoder with a stepper for feedback. We have them on the lead screws for our cnc. The counts per rotation are matched with the micro steps to get spot on feedback. The stepper also has better holding torque, so it really is a matter of application. Drive tuning is done by engineers most of the time, and most manufacturers so have software for tuning. Again application will dictate how involved the drive tuning will be. Technicians just need to know how to hook up a drive, the program can just be downloaded on any newer drives.
Hi there, thanks for your explanations.

Welcome to inquire!

so it becomes servo motor and then the advantage of stepper motor is gone
If the Torque decreases by speed that leads to probably of more slipping and the the motor losses the accurate position ? i mean the motor will be weak and not heavy and able to resist any external pushing ? or if more speed is increasing and leads torque decreasing that makes the motor not stopping at exact position and could be slipping a few millimeters. ?
Hello Wadi B3eed, Yes this is possible if the servo is not sized correctly for the application. It’s important to remember when sizing the motor to load requirements. When using servo sizing software, the calculations take into consideration your speed | torque performance requirements for torque control. Please listen to again at 6:27 Torque control, servo controllers using torque parameters. Please listen to the video at 8:06 discussing servo error control that is used for torque, velocity, and/or position, and also we discuss how servos provide error fault limit control. I hope this helps and thank you for the very good question.
have u any motion control tutorial in your course?
No, unfortunately, not yet! But we will consider it in our planning for sure.
Sir how to increase speed of servo motor.?.it is possible to adjust speed the servo drive
Servo drives are controlled by a hardware "box" or "card" which usually is configured by attaching a PC to the drive interface. In that configuration are settings that limit speed, control direction, etc. Also, every servo motor has a rated speed, which is the maximum speed at which it can run. You will need to investigate these parameters and figure out if the speed at which you would like to run is supported by the hardware and controller. The servo speed may be able to be changed via the software that is used to configure the drive.
good job
Thank you!
Very nice
Thank you!
What about closed loop stepper motors? They have same advantages as standard steppers plus they don't loose steps, driver automatically regulate current according to the load and can overload motor for a short time if needed, which makes possible higher speeds and accelerations. It seems like the only disadvantage compared to the brushless motor is 3 times lower max RPM.
"the only disadvantage" ... I think noise is higher too, and acceleration lower if that's important
Its really intersted...
Happy to hear that!

Wouldn't high torque industrial usecases use hydraulics anyway?
There are high-torque stepper and servo motors available for use with robots that lift things and conveyor systems. Hydraulics can generate a lot more force, but it is hard to control hydraulic motors with the precision of stepper or servo motors. In most of the hydraulic applications I have done in the past, travel of pistons, etc., were controlled by hitting a limit switch at the end of travel.
@@realpars One outlier is the optics industry in this case. There are hydraulic-driven linear actuators with nanometer-precision glass scales on them. Since the fluids are incompressible, you get rock-solid, zero-backlash positioning with gigantic forces. The downside is cost.
This is why optical grinders, for example, cost an arm and a leg :P
