Features

The BA4510 is a piezoelectric bimorph actuator poled in the parallel configuration with a two-wire electrical connection as illustrated below. In addition to actuation, this configuration is also useful for sensing and vibration power harvesting.

Mounting Considerations

Bimorph actuators can be mounted using an insulated clamp or bonded to a base with a two part epoxy.

Electrical Current Requirements

The required current is I=C dV/dt, where I is the current, C is the effective capacitance, and dV/dt is the voltage rate-of-change. For a sine-wave, the required peak current is equal to:

BA4510-eq1

Where Vp-p is the peak-to-peak voltage. For a triangle wave, the required peak current is:

BA4510-eq2

Recommended Drivers

The recommended drivers and associated power bandwidth (+/-100V Sine-Wave) are listed below

PDu100b General Purpose 184 Hz
PDu100 Miniature 184 Hz
PDm200B High Performance 1700 Hz

BA4510-PCB-Conn

Range

The range is specified for an applied voltage of +/-100V. When the actuator is driving a spring, the range is reduced by the factor

BA4510-eq3

Where Kp is the actuator stiffness and Kl is the load stiffness.

Options/OEM Customization

  • Custom range and dimensions
  • Custom wiring arrangement/connectors
