Allen Bradley Servo Drivers

Hey servo guys

I have a set of 3 allen bradley 1388 DC PWM servo drivers and the
transformer (3 phase). I also have one baldor servo motor with tach and
encoder in unknown condition. I have several questions if someone is
familiar with this setup.

1) Can I use a rotary single phase to 3 phase converter to run the
transformer for these drivers? How about the "static " converters. I don't
have 3 phase power. ( note that the drives are .75Kw continous and 3.75KW
peak for each axis)

2) The drivers can drive 700 watt servo motors (150V 10 amps Cont 25 A
peak). I have no data on the baldor motor since the name plate is
illegible. any other way to identify it?

3) the motor feels a bit "grindy" can I open up the encoder end without
destroying anything? Possibly a worn bearing? How about connection
diagrams? Can this motor be sent out and rebuilt?

4) Would this be a good setup for EMC if I bought the servo-to-go board and
used it to drive the 1388 drivers? I would still need to buy two more servo
motors with encoders ($1000 a piece for new Baldors with 1000 line
encodes).

I would like to get the existing motor operational and use it to prove that
all three drivers are functional. Any help would be appreciated.
