Designing for interpersonal motor synchronization

Human–Computer Interaction, 2021
In simple terms, interpersonal motor synchronization (IMS) means people moving together at the same time.

Sensorless control for synchronous motors

2010 International Conference on Autonomous and Intelligent Systems, AIS 2010, 2010
Permanent magnet synchronous motors are used in many industrial applications because they have several inherent advantages. However, information about the rotor position is necessary even to be able to control drive speed. Conventional speed and position detection uses encoder and resolver.

Synchronous Starting of Generator and Motor

Transactions of the American Institute of Electrical Engineers, 1945
A SYNCHRONOUS motor, generator, or condenser can be started from rest, by means of shaft torque, induction-motor (amortisseur winding) torque, or synchronizing torque. This paper presents data on the last method of starting. The system studied consists of a prime mover driving a synchronous generator, and a synchronous machine driven electrically by ...

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.

"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.

Pull-in characteristics of synchronous motors

Electrical Engineering, 1935
The differential analyzer has proved its worth in solving various types of difficult problems, of which the determination of the pull-in characteristics of salient pole synchronous motors is typical; but even with the aid of this device it has been necessary in solving this problem to make several simplifying assumptions.

Synchronous motors for ship propulsion

Journal of the American Institute of Electrical Engineers, 1921
SINCE the inception and development of the idea of electric ship propulsion, the question of the possibility of using synchronous motors for such service has often been raised. Such a motor could be designed for unity power factor with a resulting saving in cost, weight, and efficiency, of both motor and generator.

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 ...

Output control of synchronous motors

Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002
A dynamic controller is derived for a synchronous motor in the case of angular position tracking, when inertia, friction coefficient, resistant torque and stator resistance are unknown or slowly varying. Moreover, we suppose that the angular velocity is not measured and its numerical evaluation is unsatisfactory. Simulations are presented.

Starting Performance of Synchronous Motors

Transactions of the American Institute of Electrical Engineers, 1927
This paper deals with the theory underlying the starting performance of the salient-pole synchronous motor equipped with damper windings. The theory, while involving some approximations, is accurate enough for practical engineering calculations. Formulas are developed for the starting torque, pull-in torque and inrush.
