PAD and NDR combined

Piezo Actuator Drive (PAD) - Standard & custom product

 

Resolution

The resolution of the system can be calculated based on the characteristics of the PAD and NDR.

 

Jitter

Thanks to the low noise on the output of the NDR, the PAD exhibits a very low jitter, which can be estimated by this formula:



Speed

The speed of a PAD motor N is proportional to the input frequency f and follows the relationship:

 

 

 

Heat generation

Piezoelectric ceramics dissipate energy in the form of heat proportional to the dissipation factor (tan δ), the tangent of the loss angle for the material. For a PAD, the dissipated energy is proportional to the operating frequency f (therefore to the speed) and can be calculated according to the formula:
