Product launch: Damage tolerant piezo actuator stacks provide high reliability
Fuse technology ensures high reliability
Standard piezo actuator stacks are very reliable. However, if one ceramic element in a standard piezo actuator stack is damaged, the whole stack will fail in short circuit. The fuse technology in Noliac's damage tolerant stacks, on the other hand, fuses out any damaged ceramic element and the remaining ceramic elements continue to operate.
All industries want their applications to have a high level of reliability. However, some industries are more sensitive to reliability than others. Naturally, there are several critical applications, for instance in the aerospace industry, where reliability is vital. Here, an unplanned stop caused by a breakdown of the application is both time consuming and expensive. Thanks to the technology of the damage tolerant stacks, the application keeps working and only declines gradually instead of stopping suddenly. The fuse technology in the damage tolerant stacks is therefore an effective way to ensure high reliability.
Product range
The standard product range of the damage tolerant stacks consists of plate actuator stacks with an operating voltage of 200 V. The plate stacks can be delivered in a wide range of heights. These are the standard sizes:
- 9.56 x 9.56 mm (length x width) – corresponding to 7 x 7 mm plate stacks
- 12.8 x 12.8 mm (length x width) – corresponding to 10 x 10 mm plate stacks
- 17.9 x 17.9 mm (length x width) – corresponding to 15 x 15 mm plate stacks
Custom solutions
The fuse technology of the damage tolerant stacks can be applied to actuator stacks of other cross-sections than the standard product range as custom solutions. Please contact us for more information.
Damage tolerant ring stacks are available as a custom solution and will be added to the standard product range at a later stage.
