Resolvers

We're raising the bar on Resolvers!

Installation Tip:

Place resolver on motor stand-off resolver mount. Push firmly into the indent and screw down all three clamping screws tightly. Now proceed with tightening the resolver/motor coupler to the resolver shaft. This is the last step. If you reverse the order of this process, you will put excessive preload on the resolver end bearings and premature failure is imminent.

Resolvers were engineered to be reliable in the harshest conditions. Resistance to heat, dust, humidity, oil, and extreme pounding/vibration makes this device outperform encoders and pulse coders.

Unlike the newer digital encoder counterparts, the resolver has infinite resolution and the potential of superior surface finishes (all other factors being the same within the machine over encoder feedback systems). The main difference is that encoders use digital (ones and zeros) signals, and resolvers use analog signals, much like the difference between the old Long Play (LP) Vinyl Albums vs CD's. Sample rate has as much to do with resolution in CNC's as it does with CD players for sound.

We recommend replacing them about every 1-2 years to steer clear of trouble!

If you have noticed a decline in your surface finishes, now is a good time to replace your resolvers....
