Low speed PM synchronous motor was used in this angular servo system,to make the whole system to get a more compact structure and higher precision.

Together with the high power amplifier OPA548,this circuit is adopted in an angular servo system using Low speed PM synchronous motor as actuator,which makes the whole system get a more compact structure and higher precision.

So in order to solve the water jet cutting technology to realize the accuracy control problem in the track system on height,based on the eddy current sensor,in view of the metal plate,the waterproofing type of eddy current automatic adjust system on height is designed,and the non-contact intelligence height control is realized.
