The C-184 OEM-board and C-185 stand-alone unit are single-channel driver electronics for PILine® ultrasonic piezomotors and PILine® stages. Piezomotor drive electronics convert analog input signals into the high-frequency drive signals required to excite the required oscillations in the piezomotor stator which and cause the motion. Both the C-184 and C-185 are available in four versions, for use with different motors and translation stages.
OEM and Integrated Electronics
The philosophy behind the design of PILine® ultrasonic drives dictates that they be easily adaptable to customer requirements. This includes making the drive electronics both independent of control signal type and available either as an OEM board or as a stand-alone unit in its own case. While the OEM boards are the most economic solution for large quantities, the stand-alone units make it possible to plug a system with PILine® stages together and put it into operation quickly and easily, for example for system evaluation purposes.
Analog Control
Both drivers control the motor speed based on an analog signal from 0 to ±10 V. With an external position sensor and a servo controller, it is possible to set up a very fast, closed-loop system.
For optimum closed-loop system performance, the C-867 (see link) piezo servo-controller is recommended.
Advantages of PILine® Micropositioning Systems
The ultrasonic piezoceramic drives used in PILine® micropositioners have a number of advantages over classical drives:
- Higher Accelerations, up to 10 g
- Speeds up to 500 mm/s
- Small Form Factor
- Self-Locking When Powered Down
- No Shafts, Gears or Other Rotating Parts
- Non-Magnetic and Vacuum-Compatible Drive Principle
