DSM's flexure-guided linear piezoelectric actuators are excellent choices for precision motion control and positioning applications. Solid-state flexures provide smooth, stiction-free, and backlash-free motion for positioning applications. Requires no lubrication. Generates no particulate.
These basic architectures have been customized many times to meet customer specifications. Contact us today to discuss your application including: UHV, Shock Hardened, Cryogenic, Non-Magnetic, Titanium, High Stiffness.
DSM specializes in the temperature compensation of piezoelectric actuators. Thermally compensated piezoelectric actuators offer a much higher temperature range as they are less effected by thermal changes.
Flexures mechanically amplify the motion of piezoelectric ceramic stacks.
The standard FPA products offer travel ranges over a control voltage range of -30 to +150V. The product list below is ordered from smallest to largest displacement range, from 80µm to 2mm.
Flexure-guided lever mechanism mechanically amplifies the motion of the integrated piezoelectric ceramic. LFPA actuators include a secondary mechanical amplification to attain motion ranges up to 10mm. Because the moving mass is typically less than that of FPA mechanisms, the LFPA architecture can enable much higher dynamic response performance.
The LPA is mechanically preloaded to ensure bidirectional operation, providing increased resilience to mechanical load when compared to non-preloaded actuators. The mechanism design provides highstroke operation in an exceptionally small package. The LPA architecture offers relatively high dynamic bandwidth capabilities for the nominal displacement range and mechanism size.
NA series actuators are direct-drive piezoelectric actuators integrated into a protective metallic frame. The frame is typically a monolithic piece of stainless steel or titanium alloy with a flexure-guided expansion component.
The frame includes a mechanical preload that maintains compression on the piezoelectric ceramic under high tensile forces and ensures successful bi-directional operation under dynamic operating conditions. The design provides increased resilience to mechanical loads when compared to non-preloaded actuators.
The NA Series designs are well-suited to many applications where high force and high frequency response are required. The NA architecture can be readily adapted and scaled to other force and stroke ranges.
