Linear motors are divided in 3 basic categories: flat linear motor (classic), U-Channel linear motors and Tubular linear motors. Linear motor technology is the best solution in the context of a low load (up to 30Kgs) because it provides the highest level of speed, control and accuracy. In fact, it represents the most desired and versatile ...
A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
An electromagnetic acoustic transducer (EMAT) is a transducer for non-contact acoustic wave generation and reception in conducting materials. Its effect is based on electromagnetic mechanisms, which do not need direct coupling with the surface of the material.
A typical test setup includes a load machine, clutch, and torque transducer. An externally applied load is used to strain, i.e., load, the motor. Using this method, simple characteristics can be directly mechanically acquired and the derived variables calculated. From the input current and input voltage, the absorbed power can also be recorded.
Components can be classified as passive, active, or electromechanic.The strict physics definition treats passive components as ones that cannot supply energy themselves, whereas a battery would be seen as an active component since it truly acts as a source of energy.
The most common driver type is an electro-mechanical transducer using a voice coil rigidly connected to a diaphragm (generally a cone).Other types have similar connections, though differing in detail, between their acoustical environment and their electrical properties.
Insides of a slip-stick piezoelectric motor. Two piezoelectric crystals are visible that provide the mechanical torque. [1]A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect.
A piezoelectric transducer can be modeled as a voltage source with a filter. The voltage V at the source is directly proportional to the applied force, pressure, or strain. [ 11 ] The output signal is related to this mechanical force as if it had passed through the filter, which gives the transducer a very high and frequency-dependent output ...
