Do you have any problems like this ?
I want a small, lightweight, high-torque motor.
Using a motor,
I want to make a product that works even in a magnetic field environment
I want a motor that maintains its posture even when it is not energized.
That trouble Our Piezosonic _cc781905-5cde-3194-bb3b- 136bad5cf58d_ Motor
!!
Piezosonic What is a motor?
Voltage is used without using coils or magnets to generate rotational energy.
It uses a piezoelectric ceramic that deforms when added.
The amount of deformation of the piezoelectric ceramic is amplified by a metal part called a stator, and by controlling the deformation, rotational motion is generated on the surface of the stator.
This rotational movement causes frictional force on the rotor pressing against the stator.
Therefore, it is transmitted and the rotor rotates. The shaft is on this rotor
It is fixed and transmits the torque and rotation of the motor to the outside.
Since this frictional force is constantly generated, it can be de-energized or uncontrolled.
The position can be maintained (high holding force), and since no gear is used for the parts, it is possible to realize a direct drive without backlash.

Features of Piezosonic Motor
Point1 High torque and quietness
Point2 High holding power when no power is applied
Point3 Compact, lightweight and thin
Point4 Can also be used in a magnetic field environment
Point5 Succeeded in extending the life
Point 1
Point 1
High torque and quietness
Point 01
Piezosonic motors are with other companies' motors and ultrasonic motors.
It is a motor with a high torque of 1.2N / m and quiet operation.
DC motor
Stepping motor
Piezosonic Motor
Motor torque-rotation speed characteristics
Piezosonic motors are 5 to 10 times more torque than DC motors of the same size and can rotate at low speeds of 1 rpm or less.
Point 1
High holding power when not energized
Point 02
In the Piezosonic motor, frictional force is constantly generated, so
It can maintain its position even when it is not energized or controlled (high holding force), it is quiet because it does not use gears for parts, and there is no backlash.
A direct drive can be realized.
For Piezosonic motors
Holds posture even when not energized.
Not a Piezosonic motor,
If other motors are used, the posture cannot be maintained when the power is off.
Small, lightweight and thin
Point
03
1
The size is
Palm size
2
500ml PET bottle half the weight
The size is the size of a palm.
3
It weighs about 250g, is half the weight of a 500ml PET bottle, and is lightweight.
Without shaft, height 2.6 cm and thin
It is a thin and lightweight ultrasonic motor with a height of 2.6 cm without a shaft.
Also available in magnetic field environment
Piezosonic motors do not use coils or magnets to generate rotational energy, so they can be used in magnetic field environments and zero gravity spaces .
It is the best motor.
Can be used in magnetic field environments such as medical device MRI
Point 04
Successfully extended life
Conventional ultrasonic motors wear heavily
It had the disadvantage of short life.
However, by reviewing the structure and materials of the Piezosonic motor, it has achieved a life of 6000 hours by intermittent operation, and it has become possible to replace the stepping motor .
Performance ratio with conventional products
Point
05
Fields where piezosonic motors play an active role
From the above five points , there are four fields in which Piezosonic motors can play an active role.
The weight of the rotating part of the Piezosonic motor is heavy.
Light and small inertia, so the drive signal is
When it stops, it instantly stops due to frictional force. Therefore , precise positioning is possible, and
Active in research institutes.
Since the posture can be maintained when the power is off, there is no need to worry about dangerous operation in the event of a sudden power failure or disaster, and it is safe and secure. Active in equipment used in factories.
Maintains posture even when the power is off, and is safe and secure without worrying about dangerous movements in the event of a sudden power outage or disaster. Can be used even in a magnetic field environment. Active in the medical field with high controllability.
-Support / Assistance-
Utilization in daily life
Four
Piezosonic motor is quiet
High and retains posture even when not energized
Active in new products that support and assist daily life due to its high level of safety .
