Dear All,
My previous post was lost.
Will greatly appreciate if anyone can help me with this.
I have some AC Brushless Servo motors (8 poles) with resolvers. However, I read from some post that encoders are preferred for CNC.
I wish to swap these with encoders from some DC servos that I have in hand. They are 1000 lines.
My questions are:
1) Will any encoders work? I am fitting them to my brushless 8 pole AC motor. Do I need to have commutation? how many commutation to phase and drive them 2/3/4 commutation encoders?? (sorry I am not sure what these are hence I am not sure what the right question is to ask)
2) When I found suitable encoders, do I need to mount them at any particular angle to the pole for effective phasing/commutation/excitation of the winding etc?
Any help is greatly appreciated!
Thanks a lot in advance!
