VSDE and Fanuc motors.

[evo4wrx]

DO you know which Fanuc AC motors can run with the VSDE.
I tried some Control Techniques which did not work even after I replaced the encoders.

Im running some 750W DC servo motors right now but they arnt very gutsy at 2Nm.

So I was hoping to goto the following as I have 2 available locally at a good price.
FANUC A06B-0522-B351 AC SERVO MOTOR +

3 PHASE
8 POLES
STALL TORQUE 22 Nm
STALL AMP 2.9 AMP
90 V
AMB TEMP 40 DEG C
EXCIT PERM MAG
INSULATION CLASS F
APPROX SHAFT DIA 1/2"

PULSE CODER :
A290-0521-V581 PULSE CODER ABS2000P

These are the other two motor options....

FANUC A06B-0315-B08-7008 AC SERVO MOTOR
TORQUE (STALL) 12NM
AMP (STALL) 7.6 A
RPM 3000
PHASE 3
150 VOLTS


OR

FANUC A06B-0128-B675#7008 AC SERVO MOTOR, USED
OUTPUT 1.4 kW
114 V
7.5 AMP
200 HZ
3000 RPM
3 PHASE
200 V INVERTER
STALL TORQUE 6 Nm
STALL AMP 10

Looks like you have the absolute encoder there, most likely off of a robot.
Does the Granite use the encoder for commutation? As the Fanuc AC servo's use a proprietary 4 bit code for commutation.

If you can get the encoder pulses off the encoder the granite devices will run it I have one that had an absolute encoder an absolute encoder but I was not able to get the encoder wired so it would work. the vsde's sense the commutation requirements and will then run from the encoder count, I just replaced the encoder with a differential encoder, I made an adapter plate to fit the motor and a nylon adapter to fit the coupling on the motor. it seems to work just fine now.

I had 2 control techniques that were resolver AC motors that I replaced with Renco encoders but the things just wouldnt run. So im a little gun shy now leaving the world of DC. The other option is i go to Faunc 10M yellow caps but all the motors around are just so old.

[evo4wrx]

Can anyone confirm if this motor will work?

Fanuc Model 10S
Type A06B-0315-B032
12 NM
3 Phase
7.6AMP
Excit Perm Mag
2000 RPM
150V
8 Poles
Pulse coder

Not so fussed about the encoder I can pull them off and replace them with my Renco encoders I have a heap spare.

[Montabelli]

I am running model 5s with some with pulse coder some with trd shaft encoders coupled to the back of a cap screw in the end of the tapered shaft that the pulse coder was bolted to. I milled a stand off that use the original mounting screws.

the specs on the model5's are 110v and 6.8 amp 5.9nm. essentially
the same motor except voltage and power so it should run the model you cited

the alpha series will work fine to but I had to change the encoder. it has a different mount system than the pulsecoders, ti has a single slot swash plate on the back of the motor . I just made a nylon part that mated with it and was able to use more of the original mounting hardware to set it up.

The B032 shows up as a 2500p Absolute encoder.
I have used a shoulder bolt with 5mm(?) thread and shoulder to suit the Renco encoder.

Thanks 10 S it is then.....that will bring the lathe upto some decent speeds and get rid of the gears finally.

[Al_The_Man]

They make nice spindle motors also.

[evo4wrx]

I think I overlooked one slight issue.

Whats the dimensions of the motor 5s and the 10 s...could anyone help me or point me int he direction for that one. Ive googled about every combination of words that might relate to it but it comes up with nadda.

thanks.
