Yaskawa USAREM encoder or amplifier options?

[CalG]

It is a series of "photo copies" of some original manuscript.

From the Yaskawa pages document reference TSE-S800. A "generic" outline of the Series R servo drives (with specs) . Is the document you have different?

The motor does appear to be a good one, and it is fitted with a gear reducer that makes it just right for this process motion application.

If budget were no consideration, I'm sure a solution would come rapidly.

Knowledge has a value as well.

I do have some of the old manuals, But the PDF you have is just a copy of what is in the manual everything is there that you need for that Motor Drive information

Is your PDF the TSE-S800 2.8C

calg,

some more info fwiw.

a motor designed for trapazoidal commutation (aka BLDC) run on a sinusoidal commutated drive can have a system performance reduction upto about 20%.

a motor designed for sinusoidal commutation (aka ac brushless) run on a trapazoidal commutated drive can have a system performance reduction upto about 20%.

ratings such as nm/amp and v/krpm have a difference factor of iirc about 1.6x between the two.

the derate is due to extra heat in the motor due to mismatched current vs motor bemf waveform: a trap designed bldc motor has a trapazoidal shaped bemf while an ac servo has a sine shaped bemf waveform.

for you, mix and matching will probably be transparent as AL attests to since who is going to realize 10% less rating? Hard for someone not familiar with it to quantify.

Al, fyi, sine bemf vs trap bemf has more to do with winding and lamination shape than magnet shape; ie., dome shaped magnets in themself do not make sine bemf: most of the magnets I see today on ac motors are still square.

calg, want to know how many "poles" your motor is short 2 of the motor leads and rotate it thru 1 mechanical rev: count the humps. humps= no of poles. this is top secret info so don;t share with others - share and I loose job security -people will know everything I know and I wont be needed anymore

calg, search ebay for CE06 kollmorgen drive; it will run your motor & encoder fine and also give u the simulated encoder output to feed on to a mach3/emc cnc controller. if you dont find what you want feel free to pm me for quote on used or new one.

With the gear reducer hanging off the front of this motor, Spinning by hand is a real chore! ;-)

but perhaps acedemic at this moment.

I have just spent over an hour looking at the documents for the CACR-SR seris drives, and I must say it's impossible to put numbers to application.

In example, there is an amplifier described as CACR-SR15BC1KSY392

The Yaskawa literature on the -SR amplifiers has no reference to BCKSY designations.

An inaccurate description? Some other literature? frustration...

I'll take a look for the Kolmorgen Drive...

Thanks

Seo perhaps?

Well, Ebay comes through...

It seems costly for a piece with damage...

To hard to turn, Just undo the 4 bolts holding the motor to the gear box & slide it off

[CalG]

Set it up in the lathe output shaft chucked up, turn the spindle slowly, observe the response on the o-scope.

I did that not long ago to take a look at the encoders. I suppose I should have checked the motor poles at the same time ;-)

[mike_Kilroy]

ya, u should find working one for that. oh well.

six "bumps per rev on the Yaskawa USAREM motors.
