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:
Where Vp-p is the peak-to-peak voltage. For a triangle wave, the required peak current is:
Recommended Drivers
The recommended drivers and associated power bandwidth (+/-100V Sine-Wave) are listed below
| Amplifier | Applications | Power BW |
|---|---|---|
| PDu100b | General Purpose | 184 Hz |
| PDu100 | Miniature | 184 Hz |
| PDm200B | High Performance | 1700 Hz |
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
Where Kp is the actuator stiffness and Kl is the load stiffness.
