Custom SA actuator design is offered and may be scoped in the form of small changes in the mechanical interface, electrical interface, impedance, or resonant frequency of the unit. Comprehensive ground up design is also offered for the most challenging of applications with full consideration of environmental and performance specifications. Vacuum compatible versions are available.
A typical representative frequency response curve (FRF) for SA actuators is shown above. SA actuators will exhibit a primary resonance at a designed frequency. The dynamic mechanical amplification characteristic near resonance can be utilized to output higher force levels for a given input power. This can be useful where power consumption is a concern. At frequencies above the primary resonance, the actuators will output forces of magnitude that is relatively linear with respect to input current. The second peak shown in the FRF at 1kHz is a resonance associated with characteristics of the host structure used during measurement.
