I bought 4 Leedan 3kw AC servo motors, new in the box for $600. The problem is the company that I got then from, builds their own digital drives as part of thier cnc retrofit system. I don't need a new system.
I want to use one motor for a spindle motor and the other 3 for the X,Y, and Z axis. I have a Grey planer mill. The table is 4"x16"x59" so it weighs a ton. I need big motors to move it.
I have emailed Leedan www.servo-taiwan.com.tw many times inquiring on how to buy matching drives for their servo motors, but I never get a reply.
How or who else could I contact to purchase drives for these AC servo motors?
The biggest thing with BLDC and especially AC servo, is knowing the commutation method as to whether if and how to integrate into 3rd party drives.
For example, Fanuc use a 4 bit binary code and interpolate this into a sign wave to simulate resolver feedback, which makes it very difficult to integrate unless the commutation is replaced with a standard BLDC encoder, which I have done in the past.
