Abstract
In this paper, a new hybrid piezoelectric motor was developed. A range of degeneracy was found to obtain multiple choice of resonance frequency by adjusting the length of the elastic blocks neighboring to the longitudinal and torsional vibrators. A template was implemented in between the longitudinal and torsional vibrators to decrease the mutual vibration effect that effectively makes the calculated and actual driving frequency nearly close. Such configuration was instrumental to preserve the expected performance and reduce the trial-and-error design overhaul process of the elastic blocks. Moreover, a dual hybrid motor was easily formed by butting each stator of the two hybrid motors together with a rotor in the middle. Case studies of both single and dual hybrid motors are presented with both simulation and experimental results to demonstrate the structure design and the degeneracy approach. Besides the convenience of structurally combining two single hybrid motors to enhance the output, it was interesting to find out whether the proposed dual hybrid motor can significantly increase either the speed or torque by using different phase control methods. Therefore, using the dual hybrid motor provides a great advantage by providing an option for pursuing higher speed or larger torque output for certain applications.
期刊介绍:
The International Journal of Acoustics and Vibration (IJAV) is the refereed open-access journal of the International Institute of Acoustics and Vibration (IIAV). The IIAV is a non-profit international scientific society founded in 1995. The primary objective of the Institute is to advance the science of acoustics and vibration by creating an international organization that is responsive to the needs of scientists and engineers concerned with acoustics and vibration problems all around the world.
Manuscripts of articles, technical notes and letters-to-the-editor should be submitted to the Editor-in-Chief via the on-line submission system. Authors wishing to submit an article need to log in on the IJAV website first. Users logged into the website are able to submit new articles, track the status of their articles already submitted, upload revised articles, responses and/or rebuttals to reviewers, figures, biographies, photographs, copyright transfer agreements, and send comments to the editor. Each time the status of an article submitted changes, the author will also be notified automatically by email.
IIAV members (in good standing for at least six months) can publish in IJAV free of charge and their papers will be displayed on-line immediately after they have been edited and laid-out.
Non-IIAV members will be required to pay a mandatory Article Processing Charge (APC) of $200 USD if the manuscript is accepted for publication after review. The APC fee allows IIAV to make your research freely available to all readers using the Open Access model.
In addition, Non-IIAV members who pay an extra voluntary publication fee (EVPF) of $500 USD will be granted expedited publication in the IJAV Journal and their papers can be displayed on the Internet after acceptance. If the $200 USD (APC) publication fee is not honored, papers will not be published. Authors who do not pay the voluntary fixed fee of $500 USD will have their papers published but there may be a considerable delay.
The English text of the papers must be of high quality. If the text submitted is of low quality the manuscript will be more than likely rejected. For authors whose first language is not English, we recommend having their manuscripts reviewed and edited prior to submission by a native English speaker with scientific expertise. There are many commercial editing services which can provide this service at a cost to the authors.
