Capable of measuring in two mechanical test scenarios: Mechanically unloaded/idlre, mechanically blocked/loaded. Measurement of electrical and mechanical dynamical data. Typical frequency ranges for electrical and mechanical parameters from 10 Hz to 1 kHz. Typical electrical powers from 0.1 to 5 Watt. Capable of measuring frequency characteristics with varying amplitudes in voltages and currents by actively driving the actuator, measuring force, acceleration and velocities. Capable of measuring the electrical properties of actuators while driving them mechanically, in those cases measuring voltages and currents. All measurements are done with respect to a common phase. Datarate >10 kHz (typically 20 kHz). Postprocessing of data for SNR-ratio, bode-plots, resonance frequencies, and many more data. Typical application of these actuators are in solid body sound generation or vibration management, or in human-machine-interfaces for vibrotactile interaction.Instrumenthttps://doi.org/10.15480/882.1531610.15480/882.15316
