- •
A comprehensive explanation on the rectangular pulse drive methodology is presented.
- •
A resonant-type piezoelectric inertia motor using a bending actuator is developed.
- •
The motor features simple mechanical and electrical design, which makes it ideal for miniature electro-mechanical device applications.
- •
In addition to larger power density, the efficiency of the prototype motor is considerably increased compared with static type inertia motor.
- •
Small rotor can provide high rotation with 5 rpm/Vpp, while a large preload can provide high torque with 15 μNm/Vpp.
