BMT 60 bimorph amplifier
For the philosophy of diving multilayer bimorph actuators under electrically preloaded conditions check brochure "piezoelectric bending elements". In this case, the ceramic is operated with permanently forward polarized voltage and thereby prevented from depolarization, so the maximum mechanical performance is achieved.
The bimorph amplifier BMT 60 has been designed to drive multilayer-benders elements in the above decried optimum way with high dynamics.
Because of the analogy of the electrical operation of antagonistic Piezoelectric stacks configuration and bimorphs, the BMT 60 can also drive complimentary acting push-pull stack arrangements. (sec. 3.1)
