Abstract
The Piezoelectric Actuator Drive (PAD) is a new
type of electrical motor that employs piezoelectric multilayer
actuators coupled with a form-fitted micro-mechanical gearing to
generate rotary motion. The PAD is precise, having a positioning
error of less than 2 arc-seconds. Its typical output torque is
4 Nm, without any additional gearing. The whole motor is fully
non-magnetic, enabling its use in applications where magnetic
neutrality is of importance. The main challenges of the PAD are
the hysteretic behavior of the ceramic actuators used and their
highly capacitive nature. After compensating for the hysteretic
behavior, the current waveforms of the motor can be used
to extract all necessary parameters for sensorless operation.
Moreover, these signals provide a qualitative information about
the precision in motor centering and show any mismatch between
the actuators used.
