RE: [CAD_CAM_EDM_DRO] Motorising a rotary table

I don't know that a servo motor is required here. I would need more
detailed information on exactly what you wish to accomplish. It may be
possible to do it with a reversing AC motor. If you have 3 phase power
available that would be fairly easy. Of course you can purchase reversible
single phase AC motors and would need to wire a relay (contactor) circuit to
take advantage of the reversing feature.



Give me some additional info and I can probably help you. Email me at my
private Email below if you wish.

Subject: [CAD_CAM_EDM_DRO] Motorising a rotary table





I have a 400mm rotary table that I wish to mechanise and understand that I
need to fit a servo motor to it. I would propose to mount the motor to the
input shaft after removing the handwheel .

Doing the mechanical is not a problem for me and even the wiring if I know
what to do. Please can anyone help me with information of what I need to buy
and how to wire things up. The handwheel to table ratio is 40:1 and I need
to be able to control the table rotation from zero to 5 rpm.

I envisage controlling the motor either from a switch or a foot pedal. It
would be handy if the motor could cause the table to rotate once and then
stop but this isn't vital.


Many thanks for any help that may be given.

Mike
