Abstract
A slotted bus bar for a piezoelectric solid state motor stack having a housing encasing a plurality of piezoelectric disks which are interleaved with a plurality of electrodes. When the electrodes are connected to the slotted bus bar and the bar is biased by a source of electrical potential, an axial displacement is produced between the opposite end surfaces of the piezoelectric stack. The slotted bus bar has a spine and an attached or integral connector for connecting the slotted bus bar to a source of electrical potential. Also, the slotted bus bar has a plurality of integral ribs extending from the spine, between which are formed slots. When the slotted bus bar is assembled with the piezoelectric stack, the electrode tabs fit into the slots and contact the slotted bus bar. As results, the electrodes are structurally supported and good electrical contact is assured.
