Résumé

This paper is related to the characteristics of a traveling wave ultrasonic linear motor. After a brief state of the art of this type of motor, the working principle is presented. Then, to describe analytically the phenomena existing, a theoretical model is built using wave theory and contact mechanism laws. Analytical modeling is then validated by FEM simulations. Transient and steady-state responses of the system are obtained. In function of the voltage applied to the piezoelectric ceramics, the deformation amplitude of the stator is achieved. Harmonic analysis is also performed to find out the resonance frequency of the system and thus achieve a maximal amplitude response. Different geometries and materials are simulated with the aim of obtaining the greatest deformation amplitude. The different results will then make it possible to validate the analytical model and show if the hypotheses made at the beginning match with the reality. ©2004 IEEE.

Electric motor

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

AC motor

An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings.

DC motor

A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motors widely used, as they could be powered from existing direct-current lighting power distribution systems.
