The permanent magnet synchronous motor

Proceedings of the Institution of Electrical Engineers, 1962
A synchronous motor, constructed by modifying an induction motor by fitting a permanent magnet inside the squirrel-cage rotor, is very useful for drives where synchronous operation is required or where the drop in speed of an induction motor is too great.

Summary on development of permanent magnet synchronous motor

Chinese Control and Decision Conference, 2018
Permanent Magnet Synchronous Motor(PMSM) has the advantages of small size, light weight, high power density, and have excellent dynamic response characteristics, which make them very suitable for high- speed applications.

Design Optimization of Synchronous Reluctance Motor for Reducing Iron Loss and Improving Torque Characteristics Using Topology Optimization Based on the Level-Set Method

IEEE transactions on magnetics, 2020
Because the synchronous reluctance motor (SynRM) does not require a rare-metal-based permanent magnet (PM), the demand for SynRMs is progressively increasing because of the inexpensive design.

Synchronization in perceptual motor integration

International Congress Series, 2007
We studied changes in neural synchronization during the learning and stabilization in a perceptual motor task involving polyrhythmic bimanual force production. Effects of inter-hemispheric synchronization, captured in terms of changes in time-resolved phase synchrony, were clearly related to the stability of motor performance and could be interpreted ...

"Angle Switching'' of synchronous Motors

Transactions of the American Institute of Electrical Engineers, 1935
Commercial applications of ``angle switching'' of synchronous motors are given especial attention in this paper. ``Angle switching'' refers to a method of starting synchronous motors whereby the time of application of the excitation voltage with respect to the relative angular position of the field poles and the impressed voltage is controlled.

Dynamic Performance Analysis of Permanet Magnet Synchronous Motors Magnet Synchronous Motors

IEEE Transactions on Power Apparatus and Systems, 1984
Unlike conventional synchronous motors, a permanent magnet motor develops considerable break torque during its asynchronous mode of operation. An accurate prediction of the run-up characteristics of these motors is quite important. This paper presents the results of digital computer simulation of the transient performance of P.M.

Development of an Electric Vehicle Synchronous Reluctance Motor Drive

IEEE Transactions on Vehicular Technology, 2020
This paper presents the development and control of an electric vehicle (EV) synchronous reluctance motor (SynRM) drive. A bilateral DC/DC converter is used as an interface between the battery and the motor drive.

Complete Synchronous Motor Excitation Characteristics

Transactions of the American Institute of Electrical Engineers, 1925
Synchronous motor excitation characteristics published hitherto have been incomplete. If theoretically determined, while forming closed loops, some doubt as to their accuracy has been entertained. When determined experimentally, thay have not been complete, in that the so-called unstable portions of the curves have not been obtained, and generally ...

Synchronization of Reluctance Motors

IEEE Transactions on Power Apparatus and Systems, 1981
In most of control and industrial applications, a high degree of rotational stability and uniformity of speed is required. These requirements can be achieved by using reluctance motors. The synchronization process of such motors is of prime importance for these applications. Therefore, a simple and accurate criterion is developed to define this process.
