RESOLVER MOUNTING
11 11
The resolver shaft and stator should NEVER be rigidly coupled to the machine shaft and stator. Either the
shafts or the stators should have a flexible member which will allow freedom of movement in all planes except
rotation. (No two shafts ever have equal runout regardless of their precision. Even if individual shaft
assemblies have the same "amount" of runout, these assemblies will have different patterns which result
in different magnitudes at various rotational positions. This applies regardless of bearing types.)
If a pulley or sprocket is to be mounted to the resolver shaft, DO NOT hammer or force fit it onto or off the
shaft. If the resolver is belt or chain driven, DO NOT overtighten the drive belt or chain. To much side loading
can destroy the resolver bearings.
If these mounting rules are ignored, (warranty will be void) the machine shaft assembly will "fight" the resolver
shaft assembly and the final result will be failure of the weakest bearing.
