The inertia depends mainly on the diameter and not on the length. In order to nevertheless achieve the necessary motor torque, servo motors usually have an elongated shape.

I don´t know if I understood you right. You can get servo motor with different IP. The feedback loop ( for example by a resolver) provides the information about rotational speed and the angle of the rotor.

Thanks for the reply, I work with servo motors on injection molding machines and I've noticed they seem to run rather hot even at normal load and also seem to be built rather air tight, external cooling fins instead of any internal air cooling and was just wondering if that's why they need an internal dust free environment for the built in positional feedback loop system.

@@darrylanton9323 Some that are built for continuous operation incorporate separately powered cooling fans. Servos aren't cooled by a shaft-driven fan like typical AC motors because they are used in applications where they run for short duration or at low speeds. They have to dissipate the heat through the case or add external means. If your servo motors get really hot while holding one position, the tuning of the servo drives may be too aggressive.

Yep, I've seen that some of our newer large machines have incorporated blowing fans mounted on the end of the servomotor directing air up the external fins towards the business end. The new hybrid machines that incorporate hydraulic pumps driven by servomotors are more economical then full hydraulic and don't require as precise tuning as full servo electric machines do, luckily these full electric machines have a graph bar (0-100%) that's shows the servomotor load on each of the four variable servomotors that run during the process so adjustments can be made before overloading the motors and shutting the machine down.

@@darrylanton9323 it will be air tight if the output shaft has oil seal.such small opening does nothing to cooling. from the encoder end it must be sealed, because any contamination to encoder harm.

First: Any motor used for positioning in e.g. CNC machine or robot can be called "servo motor". A servo drive must have a feedback system. The stepper motor can be clasified as a DC motor. A RMF is created by switching the stator voltage on and of or by reversing the polarity of the voltage. A hybrid-stepper has very small step-angles. Driven in microstepping mode you nearly cannot notice the steps. For very simple position you can use stepper without a measuring system. Talking about an AC servo motor you usually mean a 3-phase-synchronous motor. The current within the stator winding is steady or analog. This motor makes no steps like the stepper motor. Very small industrial robots, like Misubihi offers, use stepper motors as servo drive. Bigger robots (Kuka, Fanuc, etc.) use AC servo drives.

Steppers usually move 200 steps per revolutions and no feedback means there is no guarantee that the motor actually moved those steps. Servos on the other hand have high resolution encoder feedback. I have seens servos with 2000 to 65536 pulses per revolution. This means that you can control the shaft movement with a lot more accuracy. So the answer to your question is that servo motor can make small controllable "steps", much smaller than a stepper. Although they are done in an analog fashion.

servo motors and induction motors have one thing in common: the rotating magnetic field. Servo motors have a permanent magnet as rotor and induction motors a "squirrel cage". Inthis vid I explained the RMF: kzfaq.info/get/bejne/rLOlaaeey7GshKc.html

Induction motor with encoder feedback and vfd can be used as servo motor but is not commonly used in servo systems. Permanent magnet motors are best for servo systems because of their high starting torque. Direction of ac servo can be changed by swapping two leads but no one does that because it is needless. Servo amplifier can do this without swapping any leads. It can do other advanced things like torque, speed and position control

The drive has to be connected according to right turn phase sequence . If not, or one is missing, it gives a fault phase sequence error. The motor has to be connected accordingly ( U,V,W ) The shaft encoder on the motor will detect wrong turning direction. Direction, speed ( = frequency ) ... can be easyly set by parameters. Some drives like Siemens Micromaster can be set using parameters that inputs on the terminal can be used to determine speed and turning direction. It even supplys the 10 V operating voltage conviniently.

Hi - this animation is made with Blender.

I use Blender

hi thks

hi

if the isolation between the coilwindings is still intact it should work anyway.

Check coil resistance between the phases. It should be very small (a few ohms) and equal to each other. Check the resistance between each phase and the motor body. It should show an open circuit. If this is not the case the motor is gone.

Yes you can drive a servo motor by pulse and direcion signal. Servo motor is widely driven using pulse dir signals. It is called position control mode of a servo motor.

Hi -Thank you friend

Then explain it better

Servo motors are used together with a closed-control system. But brush-motors in general are used less and less because their high wear.

Brushed servo are not very popular but we have two out of 10 cnc machines in our factory which use brushed dc servo motors. A 1990 model Anilam milling machine and 2002 model Euromac MTX 1250 turret punch press. Generally speaking any actuator which can propotionally control a variable using feedback is a servo system. Even induction motor with encoder feedback and a vfd can be used as a servo motor.

Here Blender is used. But you can also use Maya or Max 3D - for example.

Thank you so much! video so great!

software is called Blender.

@@learnchannel-TV How much time does it takes to create such an animation? I work with Solidworks Composer and want to know the difference.

@@mk-zm6lu I really cannot say because I made this vid during my fulltime job. It also depends on your equipment. I needed 2 months more or less - but I had a fulltime job.

@@learnchannel-TV 2 months?! Too much. Even a week is too much. If you want a simple tool, use SW Composer. Although it doesn't have all the abilities that Blender has, apparently.

@@mk-zm6lu I made this vid during my full time job during my spare time. I like Blender - it is very powerful. If you work with Blender daily you can make in in one week - yes.

@@learnchannel-TV I am an electrical engineer student and I want to incorporate animation in my presentation at school. could you recommend a website to get free models.

Make a search with keywords like Blender, car, model and you will get some hints or suggestions for a car modeled with Blender. Some models

@@MrDapo1999 are you presenting Servo motors at your school?

@@onurozdemir2898 I tought electric drives in a technical school

Actually any particular names don"t matter (any servo amplifier has a lot of feedback systems: at least for INSTANTANEOUS current control). For example yaskawa name the controller as servopack(that is their protected trademark). So it can be {servodrive,servopack, servocontroller, servoamplifier, servodriver }...

I can give you the text in english as a pdf-File. You can help this chanel if you translate he text in your native language. Contact me via e-mail: info@learnchannel-tv.com

ok this is my e-mail mnmostabchir@gmail.com

Motor de passo é classificado como motor CC. O motor síncrono trifásico síncrono tem uma tensão de alimentação e controle diferentes. Mas você também pode usar o motor de passo como um servomotor.

I like this
