Hi All
I was wondering if anyone had experience with driving a single ballscrew
with two similar DC motors, one at either end?
So we have;
- one ballscrew
- one rotary encoder
- one servo drive
- two DC servo motors, one at either end of the shaft
One will obviously turn 'backwards' relative to the other, not that that
should have any bearing on anything.
I'm trying to figure out if there would be a detriment to connecting the
motors in parallel to one servo drive. Availabe power is not a problem, but
possible current-interplay between the motors is.
Perhaps they should be in series, but peak current would be halved.... One
motor would always draw a bit more power, but the servo drive will see a
single load.
Anyone come across such a system in the real world?
Regards
Roland
