Piezoelectric Ultrasonic Motors - Piezo Tech
Piezo Tech produces various ultrasonic motors; the Tiny Ultrasonic Linear Actuator (TULA), the Piezoelectric Ultrasonic Motor Linear(PUML) and the Piezoelectric Ultrasonic Motor Rotary (PUMR).
The TULA
Next generation actuator driven by linear motion of unimorph or bimorph piezoelectric body.
TULA XX-OOO (XX: diameter of piezoelectric ceramic, OOO:length of the rod)
Operation principle
The operating principle of the TULA is explained by the characteristics of the piezoelectricity and Newton's first law. In other words, the TULA exploits the vibration modes of the piezoelectric ceramic, the inertia principle and the contact force of the friction.
Fetures- Very small size, light weight and simple structure
- Variable stroke
- Quick response
- Hard brake with no backlash
- Excellent conrollability
- Fine position resolution
- Quiet drive
- Unaffected by external electric or magnetic fields
