Hello ACC Community!

I would like to control the AC servo motor from the microcontroller. I want the servo to return some position, servo start, servo stop, return to a home position

I am looking for information to drive the AC servo motor https://www.ebay.com/itm/200W-Delta...20V-3000rpm-Keyway-Oil-Seal-New-/122118865696. I know microcontroller can’t drive AC servo motor directly.

I see, many drivers are available in a market.

Can somebody suggest me compatible driver module for given AC Servo Motor

 

... An AC servomotor requires a specific amplifier. A DC analog control signal is converted by the amplifier module to an AC waveform that is compatible with the motor. For the various options that you list, you might want to inquire with a commercial package developer such as Galil. The motor which you have listed only shows to have 0.64 n-m static torque, which is less than one ft-lb. The rated watts apparently occurs at some higher motor rpm.

 

Do you want a pulse type control or ±10vdc analogue ?
Is it actually a AC servo motor or a BLDC, physically they are practically identical, the only difference is in the commutation fitted, do you know if it has hall effect type, if so it is BLDC control.
I generally use BLDC and A-M-C drives, but these have the ±10vdc, if you need step direction there are quite a few options.
AC is not so common.

Link show it's a AC servo motor. My question is how to drive this motor if want to control it from microcontroller

 

Why not ask the Ebay seller which of the controllers they sell would work?

You need to find out if it has any kind of commutation device, and if so, what is the nature of it, resolver etc?
According to the spec sheet, it has a 17 bit incremental encoder.
Which it most likely also uses for commutation.
