MTDD Series - Magnified Piezoelectric Actuators

MTDD16S750F90 LG

The MechaTrans®DD-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®DD-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®DD-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®DD-Series, it elongates as shown below.

Quality / Testing

Each actuator is individually tested for displacement range, blocking force, and resonance frequency.

Mounting of actuators

The MTDD actuators can be mounted in a free-free or fixed-free configuration using the threaded mounting holes. When a voltage is applied, a proportional expansion is developed in the vertical direction, as illustrated below.

Tension Force

The maximum tensile force generated by the actuator is approximately 10% of the compressive or blocking force.

Displacement Range

The displacement range is specified for an applied voltage of -20V to +150V. The displacement listed in the charts is the nominal displacement @ 150V. If the input voltage is unipolar (0V to +150V) the specified range is reduced by a factor of 0.9.
