Amp side Delta, Motor side Wye or vice versa <-- Would it be fine for a sinusoidal setup?

And silly question but would this create phase shift of 30 degrees? (I guess not because unlike...

Sorry Al, yes I was talking 12 "pole" BLDC and my hypothetical question was loose at best since I was disregarding the feedback mechasim, a possible sequencing circuit in the BLDC as donde mentioned...

I have this weird habit to ponder upon something seemingly irrelevant but many a time it gives me a new perspective of things. I think the answer to my question "What happens when 3-phase sinusoidal...

Thank you. I just read some of the articles... but I just can't point out what I am not getting though I do feel that I am not getting something right... I feel that I will get it once I could answer...

My understanding is that a 3 phase sinusoidal AC servo makes one turn(rotation) for each sine cycle. Now can there be a sinusoidal AC servo that makes half a turn for each sine cycle? (maybe a 6...

Thanks Al,
I just want to make sure if the concept below is really true.. cause I still can't believe it...


"Is it really possible to isolate the "torque facor" only,, and controll it without...

Hello,

I'm coming from robotics background and at first glance it looked as though cnc world had a lot to catch up but last couple of days I spend scores of hours reading this forum and looking...

Thanks for your thoughts.

I found Rutex does this. Their newer Rutex R2000 series use SPI communication: Basically a serial communication through parallel port. 32-bit too! This means this drive...

Wow Rutex does that through serial interface and costs 150!
Would you or anyone else know any more of these types? Please let me know any and all servo drive that is capable of receiving ASCII or...

Hi,

I pursue robotics as hobby and these days there are 32-bit motor controllers that operate in 10+ MHz refresh rate that can perform amazing number of PID calculations per sec and this type of...

Hi I am a self learner and my question may sound clueless but I'll give a shot anyways.

1.
Can I use an oscilloscope or any pulse generator as a pulse source to control any given servo...

wow Thanks Epineh! That's one nice price for an index ch. encoder. Spec looks super too. Have you tried it yet?

Hi, please recommend cheap incremental encoders with index channel. Least expensive US digital's ones with index ch. were about $40. Are there cheaper ones out there? Thanks..

Hi I'm new here. Well my question is, does "absolute encoder" always require a computer to operate? Are there inexpensive Gecko G340-like drivers that will interface with absolute encoders without...
