Electromechanical drive, has motor, which can be rotated against shaft in specific angle range and ascertained at each angle, and including finger, where friction contact between finger and shaft is maintained for linear and/or rotary drive
摘要
<p>The drive has a piezoelectric motor (3) including a drive finger (3a), which can be shifted in a piezoelectric manner in oscillations. The drive finger stands in friction contact with a shaft (1) and swings to feed the shaft parallel to its surface. The motor can be rotated against the shaft in an angle range of zero to ninety degrees and can be ascertained at each angle. The friction contact between the drive finger and the shaft is maintained for a linear and/or rotary drive.</p>
