Design your own stack
Noliac Piezo Actuators
Noliac's standard stacks are designed with 1mm thick PZT endplates on top and bottom of the actuator, and n active single actuators.
The total height of a SCMA can be estimated by the following equation:
H SCMA = n x H CMA + 2
Where: n = number of single actuators constituting the stack H CMA = height of the single actuators constituting the stack [mm]
Height of a a stack made of 14 CMAP7.
H CMAP7 = 2mm
H SCMA = 14 x 2 + 2 = 30mm
Free displacement at maximum operating voltage
The maximal free displacement dL of a SCMA can be estimated by the following equation:
dL SCMA = 0,9 x n x dL CMA
n = number of CMA's constituting the SCMA
dL CMA = maximal displacement of the CMAs constituting the SCMA [m]
Displacement at 3KV/mm of a SCMA made of 14 CMAP7.
Displacement dL CMAP7 =3,1µm
Displacement dL =0,9 x 14 x 3,1E-6 = 39E-6m = 39µm
Note that those equations are only given as an indication. Please refer to Noliac for exact specifications.
