FAQs

What are the different types of ultrasonic motors? ›

More generally, there are two types of motors, contact and non-contact, the latter of which is rare and requires a working fluid to transmit the ultrasonic vibrations of the stator toward the rotor.

An ultrasonic motor rotates a rotor by using ultrasonic waves with high frequencies more than 20,000Hz which a human cannot hear. The ultrasonic motor generates ultrasonic waves using piezoelectric elements, while conventional motors use permanent magnets or coils to rotate a rotor.

It has been known for more than 30 years now, that the first ultrasonic motor was introduced by V.V Lavrinko in the year 1965. An ultrasonic motor is a type of electric motor produced from the ultrasonic vibration of a module; the stator will be placed against the rotor depending on the scheme of operation.

In future, these motors may find applications in the fields like automobile industry, nano-positioning, microelectronics, Micro Electro Mechanical System technology and consumer goods.

The term “sonic” refers to sound waves in the region of 16 Hz up to 20 kHz, whereas ultrasonic waves range from 20 kHz to 1 GHz.

streaming velocity of the irrigant has an effect on the cleaning efficacy. The streaming velocity is related to the frequency and the frequency of sonic equipment is between 1000 and 6000 Hz and ultrasonic is at least between 20,000 to 30,000Hz (Table 2).

Ultrasonic motors, which have superior characteristics like high torque at low speed, absence of magnetic interference, and compactness in size, are good candidates for medical applications, automation, robotics, aerospace engineering and various other fields.

Sonic used the Super Emerald to transform into Ultra Sonic, leading the Time Beam away from Knothole and allowing himself to get hit by it. Sonic remained unaffected other than gaining green eyes. Ultra Sonic also has an open connection to the Chaos Force, such as using Chaos Control to fire a powerful energy beam.

A piezo motor is a device that can be used for a variety of precision applications in many different fields. The basic purpose of piezo motors is to generate motion based on small deformations of a material when an electrical current is applied.

Ultrasonic resonant motors (PILine^®) are characterized by very high acceleration and speed to 800 mm/sec and feature a compact and relatively simple design. Piezo-Walk motors (piezo stepping motors) can achieve much higher forces and picometer range resolution but are not as fast.

What is the application of ultrasonic motor? ›

Ultrasonic motors provide precise and controlled motion, making them ideal for robotic arms, grippers, and other robotic components. They enable robots to perform tasks requiring high precision, such as assembly, pick-and-place operations, and even delicate surgery in the field of medical robotics.

Ultrasonic motor (USM) is an actuator that converts characteristic vibration (resonance) of several μm in amplitude generated in the metallic elastic body (transducer, stator) into rotation or translational movement of motive elements (rotor, slider) with friction.

Disadvantages of Ultrasonic Testing Techniques:

More expensive than other methods. Difficult to use on thin materials. Part Geometry can cause complications. Needs relatively smooth surface to couple transducer.

Some common disadvantages of conventional ultrasonic sensors include limited testing distance, inaccurate readings, and inflexible scanning methods. All of these drawbacks, however, can be mitigated and even overcome with the right NDT tools and techniques.

Ultrasonic units have their own electric generator, separate from the dental unit. They also have their own foot pedal which attaches to the device itself. There are two types of ultrasonic scaler devices: magnetostrictive and piezoelectric.

According to the working modes of ultrasound, it can be divided into dynamic ultrasonic equipment such as continuous and circulating type, and static ultrasonic equipment such as ultrasound baths and ultrasound probes [14], the static ultrasonic equipment being more commonly used in the laboratory.

Longitudinal wave and transverse wave

There are types of ultrasonic waves, longitudinal wave, transverse wave and surface wave, etc.
