Fast Response Multipole Solenoids

The growing need for solenoid actuators capable to provide both high traction force and fast response is reviewed. A new concept of a fast response multipole solenoid is described, and a discussion of factors leading to faster solenoid response is given, An improved schedule of energy input into the solenoid coil is suggested, and an analysis of the dynamics of the armature motion and its correlation with changing electric and magnetic parameters during the solenoid activation period is performed.
