Very use full. Thanks lot...

Wow,learnt a lot,thanks!

An useful information about the servomotors

[@sudhirpatil3434]

good information!

[@Dipplers]

I know this is old but do you have any videos of showing the inside of newer compumotors like the SM series or the BE series motors?

Hola buenas noches, soy emilio trabajo en mantenimiento, gustaría saber si un servo motor se puede controlar la frecuencia de velocidad con un variador sin usar un driver o PLC, lo que busco es rotación constante para adaptar a un enroscador de tapas, mucha gracias..

[@JoHoMoCo]

emilio cossio Pardon, what is enroscador tapas? A servo motor's current is proportional torque and that's controlled from a servo drive. Servo drives can be in analog torque mode (+-10volt dc) or analog velocity mode (+-10volt dc) or in position mode. There are servo drive controllers that can be programmable to also control the motion or run a program. You could have a servo drive in velocity that would run proportional to the analog +-10vdc signal. You can also do gearing to follow an external encoder. Or you could have a motion profile programmed in the servo drive controller. A PLC can do many things and they can output analog signals but they're not great at doing motion control. What are you trying to do?

Automation Engineer muchas gracias, se le agradece mucho..

second half rotation D C electrical motor , let me get details

[@DeathGhost809]

i heard that servo motor unlike normal motors it can stop rotating once it cut off electricity, is that right?

[@JoHoMoCo]

medo sam Servo motors are not powered directly but rather through a servo amplifier (sometimes called a drive). They have an enable input that a controller can enable/disable the drive. In safety conditions, you'd cut the power to the servo amp/drive which would remove power from the motor. Some amps/drives have separate control power than motor power so you can still communicate and keep power on the feedback device (so you don't have to rehome/reference the machine when you power the drive again, or you can communicate to it to see if there's a fault). Other drives have Safe Torque Off inputs that are a relay for the machine safety circuit that are a hardware controlled (not software controlled) switch that removes power from the motor at the drive. Servo motors without a brake are free to spin when powered off. Servo motors with brakes are almost always fail-safe brakes that you must apply power to the brake to disengage it from the motor shaft. Thus in the event of power off the brake engages the motor shaft and holds the load.AC induction motors can be power directly from AC voltage but only at 1 speed. For multiple speeds, a Variable Frequency Drive (VFD or sometimes called an inverter) can be used. But again, you cut AC power and it's not spinning.Stepper motors are powered from stepper drives (most are not called amplifiers as you set the current for the motor and it's running at full current most of the time -- not amplifying an analog error - see my PID servo loops video). Stepper motors are typically 1.8 degree step motors which are a 50pole. They have much higher detent due to the high pole count and cog when you feel them (not energized) - though I'd estimate it around

[@MANOJKUMAR-hv6oi]

Please share video of all type motor winding. Conceptsize

[@JoHoMoCo]

Good idea and yes its something I could cover in a new video. It'd be similar to the differences in linear servo motor windings: kzbin.info/www/bejne/h6rUnqR8hq2recU

[@MANOJKUMAR-hv6oi]

I need a video in which servo motor 36 slot wind very slow so that I can wind it.

[@JoHoMoCo]

You'd need to search further. Winding motors specifically isn't my area of expertise. I'd suggest checking motor manufacturers or local motor repair shops.

Did this take place in the centre of nuclear explosion?

[@JoHoMoCo]

Charles Otz Ha! Yes, it’s an older video but is still great showing the inside of motors. Hope you found it informative!
