R2030 with 1kW and 400W sanyo motors ?

[andy55]

Hi, I have some 1kW and 400W Sanyo 100VAC brushless servos (from surpluscenter).

I'd like to hear from people who are using the rutex with the R2030 drive.

- does the hall sensor based commutation give smooth rotation ? suitable for direct coupling to a 2.5mm pitch ballscrew ?

- what kind of following error, in encoder counts, can I expect ?

- cooling ? I'm assuming these drives will need an external heatsink and a fan ?

edit: another question: does the encoder interface operate in 1x or 4x mode ? The servos have 2000ppr encoders, which operated in 4x mode give 8000 counts per revolution. at max speed 3000rpm, this is 400 000 counts per secod. can the rutex drive handle this ?

edit2: the drives are rated "100V". Does this mean 100 VAC, as for the servos ?, or does it mean that the DC input voltage to the drive is max 100V DC ? If the latter, it means that the full power of the motors cannot be utilized since it's not possible to output a 100 VAC AC signal using a 100V DC rail ??


thanks,

Andy

if you are doing direct drive you probably wont run the motors anywhere near max rpm, so running them at a lower voltage shouldn't be an issue. max Rpm is proportional to voltage, and torque is proportional to phase current. I believe that the voltage rating is dc bus voltage, as with bldc motors, and the AC part only refers to sinusoidal commutation, however you may want to check that with the spec sheet, as i run mine at 60v instead of 100v, so havent tested it.
