Accurate magnetic alignment of rotor and stator and mechanical alignment of encoder disk to shaft and encoder pickup to stator, possibly done by generating a known stator field angle at enough current to swamp out friction, thereby setting the rotor position, and then aligning the encoder to that position. A fussy job with many many ways to go wrong. > >> [EMAIL PROTECTED] wrote: >>> Hi >>> I am looking for more info about why I can not take out encoder from AC >>> servomotor and put another in? >> If the motor has commutation sensors (Hall signals) built into >> the motor, and separate from the encoder, then there is no problem. >> >> Many newer motors, like the SEM and Servo Dynamics, have >> integrated these functions, and so the commutation encoder needs >> to be accuratly aligned with the motor position. >> w >> Jon >> >> ------------------------------------------------------------------------- >> Check out the new SourceForge.net Marketplace. >> It's the best place to buy or sell services for >> just about anything Open Source. >> http://sourceforge.net/services/buy/index.php >> _______________________________________________ >> Emc-users mailing list >> Emc-users@lists.sourceforge.net >> https://lists.sourceforge.net/lists/listinfo/emc-users >> > > > > ------------------------------------------------------------------------- > Check out the new SourceForge.net Marketplace. > It's the best place to buy or sell services for > just about anything Open Source. > http://sourceforge.net/services/buy/index.php > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.
