Piezoelectric motor having a main body structured as a polygonal prism

An air motor for converting electrical energy into kinetic energy and using the kinetic energy to generate a specified air pressure and an air flow at a specified airflow rate, the air motor comprising:

• a main body comprising at least one unit structure;
• and
• a piezoelectric actuator disposed within the main body and comprising:
• a suspension plate, wherein the suspension plate is a square plate and has a length in a range between 0.6 mm and 1 m, a width in a range between 0.6 mm and 1 m, and a thickness in a range between 0.1 nm and 1 m,
• an outer frame having at least one bracket connected to the suspension plate;
• and
• a piezoelectric plate attached on a first surface of the suspension plate, wherein the piezoelectric plate is a square plate and does not extend over the suspension plate, wherein the piezoelectric plate has a length in a range between 0.6 mm and 1 m, a width in a range between 0.6 mm and 1 m, and a thickness in a range between 0.1 nm and 50 mm,
• wherein the first surface of the suspension plate, a first surface of the outer frame and a first surface of the at least one bracket are coplanar with each other, and a second surface of the suspension plate, a second surface of the outer frame and a second surface of the at least one bracket are coplanar with each other,
• wherein the specified air pressure is in a range between 10 mmHg and 10000 mmHg, and the specified airflow rate is in a range between 0.1 liter/min and 1000 liter/min, and
• wherein when the piezoelectric actuator is enabled, air within the main body is controlled and driven to flow, wherein the air motor is applicable to replace various types of motors, compressors or engines,
• wherein the main body is a combination of a gas inlet plate and a gas collecting plate, wherein the gas collecting plate comprises a bottom plate and a sidewall protruding from the edges of the bottom plate, and an accommodation space is defined by the bottom plate and the sidewall collaboratively, wherein the piezoelectric actuator and the gas inlet plate are disposed within the accommodation space.
