TULA(Tiny Ultra Sonic Actuator)

Product Information

• Using linear motion of rotor due to rotary motion of Uni- or bimorph piezoelectric body
• Tiny Ultrasonic motor usable in cellular phone and information machinery

Driving Principle
The linear motion occurs by combination of two mechanisms.
Step1. The flexural vibration of the transducer
Step2. The principle of intertia at the shaft

Type

Features

• Very small size , Very light weight, Simple structure
• Very high driving power, Low power consumption
• Minimizing sound, None electromagnetic waves, Possible linear driving without additional equipment

Applications

• Low Speed, High Torque
• Camera phone, PDA etc,
• Semi-conductor, Small Robert, MEMS, precision instument
