The MechaTrans®K-Series is a piezoelectric actuator that has a higher rigidity/stiffness and higher resonance frequency compare to the MechaTrans®DD-Series or the MechaTrans®D-Series. Therefore the MechaTrans®K-Series has a shorter rise time. The MechaTrans®K-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. However, the magnifiation / amplification ratio is smaller than the MechaTrans®DD-Series or the MechaTrans®D-Series. Like the MechaTrans®DD-Series or the MechaTrans®D-Series, the MechaTrans®K-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®K-Series, it shrinks as shown in Fig. 2.
Features of the MechaTrans®K-Series
- High resonance frequency.
- High blocked force.
- Fast response / Short rise time
- Flat and compact.
- Output stroke of the piezoelectric actuators is converted to 90 degrees in direction.
- The MechaTrans®K-Series shrinks as Fig.2 when a voltage applied.
- Output stroke direction is opposite to the MechaTrans®KK-Series
The operating principle of the MechaTrans®K-Series
Mechanical tapped holes are fabricated at both sides of the MechaTrans®K-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®K-Series shrinks as shown in Fig. 2.
