Users can integrate these in stages themselves. The operation of ultrasonic piezomotors requires electronics that generate high-frequency AC voltage to excite the piezoelectric actuator to oscillations. The C-872 universal drive electronics is suitable for the entire range of PILine drives. A new type of power transfer prevents heat generation in the electronics and optimally adjusts the operating frequency. The drive thus works with maximum efficiency. It is controlled via an analog interface in the range between +/- 10 V.
Drive systems that are based on ultrasonic piezomotors offer advantages over classic motor-spindle systems in respect to dynamics as well as velocity, start-stop behavior and installation space. They are also considered an alternative to magnetic linear motors when e.g. the target position has to be kept stable without the drive being supplied with current or in the case of strong magnetic fields.
