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.

​Without shaft
Height 2.6cmThin

​It is a thin and lightweight ultrasonic motor with a height of 2.6 cm without the shaft.

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.

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.

日常生活での活用
工場での活用

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.
