What is a piezosonic motor?
Rotational energy is generated without using coils or magnets, but by applying voltage.
It uses piezoelectric ceramic that deforms when applied.
The amount of deformation of the piezoelectric ceramic is amplified by a metal part called the stator, and by controlling that deformation, rotational motion is created on the stator surface.
This rotational motion causes a frictional force on the rotor pressing against the stator.
This causes the rotor to rotate. The shaft is fixed to this rotor and transmits the motor's torque and rotation to the outside.
Since this frictional force is constantly generated, even when the power is not energized or controlled,
It can maintain its position (high holding force), and since no gears are used in the parts, direct drive without backlash can be achieved.

The piezosonic motor has a high torque of 1.2N/m and operates quietly compared to other companies' motors and ultrasonic motors.
Point 02
High holding power when no current is applied
Piezosonic motors generate frictional force all the time, so they can maintain their position even when not energized or controlled (high holding force), and since they do not use gears in their parts, they are quiet.
Direct drive without backlash can be achieved.
Piezo Sonic Motor
Maintains posture even when power is off
Not a piezosonic motor,
If you use other motors, the posture cannot be maintained when the power is off
Point 03
Small, lightweight, thin
②
500ml plastic bottle
half the weight
It weighs approximately 250g, which is half the weight of a 500ml plastic bottle, making it lightweight.
The size is
Palm-sized
①
Without shaft
Height 2.6cmThin
It is a thin and lightweight ultrasonic motor with a height of 2.6 cm without the shaft.
③
Point 04
Can also be used in magnetic field environment
Piezosonic motors do not use coils or magnets to generate rotational energy, making them suitable for use in magnetic field environments or zero gravity.
It's the perfect motor.
Can be used in magnetic environments such as medical equipment MRI

Conventional ultrasonic motors suffer from heavy wear.
The drawback was that it had a short lifespan.
However, by reviewing the structure and materials used, the piezosonic motor has achieved a lifespan of 6,000 hours with intermittent operation, making it possible to replace a stepping motor.

The above five pointsFields where piezosonic motors can be used
Piezosonic motors have light rotating parts and low inertia, so when the drive signal stops, they instantly come to a standstill due to frictional force. This enables precise positioning, making it useful in research institutions.
It maintains its posture even when the power is off, and there is no need to worry about dangerous movements in the event of a sudden power outage or disaster, making it safe and secure. Can be used even in magnetic field environments. Highly controllable and active in the medical field.
Since it can maintain its posture even when power is off, it is safe and secure without the worry of dangerous movements in the event of a sudden power outage or disaster. It is useful for equipment used in factories.
Piezosonic motors are very quiet and maintain their posture even when not energized, making them highly safe, making them useful in new products that support and assist in daily life.

For those who are concerned about product development
Piezosonics demands high precision
Taking advantage of our motor design capabilities and IoT technology cultivated through the development of autonomous mobile robots, Piezo Sonic works with our customers to come up with a concrete image of the product based on their image of what they want to make, and then we can prototype and mass-produce the product. We will cooperate with you.
We can also assist with conceptual design and concept design with end users in mind.
