Piezo actuator, Long stroke, Flat , Compact

Piezoelectric, Piezoelectric Actuator, compact, higher rigidity/stiffness

The MechaTrans®D-Series is a compact piezoelectric actuators that can generate large output strokes, which is 10 times and above larger than the stroke of a multilayer stacked piezoelectric actuator. The MechaTrans®D-Series consists of a stroke magnification / amplification structure and multilayer stacked piezoelectric actuators. With the stroke magnification structure, the stroke is magnified to overcome the limitation of the multilayer stacked piezoelectric actuator. The MechaTrans®D-Series is designed flat and compact in size, therefore the efficiency of the space utilization is high. The output stroke is converted to 90 degree in direction compare to the original output stroke of the multilayer stacked piezoelectric actuator. When a voltage is applied to the MechaTrans®D-Series, it shrinks as shown in Fig. 2.

 

Features of the MechaTrans®D-Series

・large output stroke

・Flat and compact.

・Output stroke of the piezoelectric actuators is converted to 90 degrees in direction.

・The MechaTrans®D-Series shrinks as Fig. 2 when a voltage applied.

・Output stroke direction is opposite to the MechaTrans®DD-Series

 


The operating principle of the MechaTrans®D-Series

Mechanical tapped holes are fabricated at both sides of the MechaTrans®D-Series. Lead wires of red and black(white) are attached at the piezoelectric actuators. Fig. 1 shows an example of the connection between the driver and the piezoelectric actuators. A resistance may be needed in between depend on the driving conditions. When a voltage is applied to the piezoelectric actuators, the MechaTrans®D-Series shrink as shown in Fig. 2.

Operating precautions for MechaTrans®

Please confirm the following operating precautions before using MechaTrans®D-Series.

1)Hysteresis

2)Continuous DC voltage under high humidity

3)Avoid excess tensile force against PZT and/or compression force to the arm

4)Do not superimpose DC voltage instantaneously

5)Ambient temperature

6)Polarization
