Torque regulation of induction motors

Automatica, 1993
Abstract A controller design methodology to solve an output tracking problem for a class of systems described by its Euler-Lagrange equations with less control actions than degrees of freedom was recently presented by Ortega and Espinosa. The procedure is based on the idea of “shaping” the total energy of the closed-loop system with the nice feature ...

Motor 'identity'-a motor model for torque analysis and control

Proceedings of 1995 International Conference on Power Electronics and Drive Systems. PEDS 95, 1996
This paper introduces a novel concept in torque analysis and torque controller design, using motor identity. The concept of identity is defined and analysis for generating an optimal input current which can produce smooth and maximum torque output is described. The extraction process of identity from a motor is also provided.

Theory of Hysteresis-Motor Torque

Transactions of the American Institute of Electrical Engineers, 1940
THE object of this study is the development of a quantitative theory of hysteresis-motor torque, especially in relation to magnetic properties and dimensions. The theory is interpreted physically in an idealized case, and applied to a particular motor to verify the result experimentally.

Use of a Torque Motor as a Tachometer

IEEE Transactions on Biomedical Engineering, 1977
Circuitry is described whereby an Aeroflex linear torque motor, used to deliver precise torque waveforms in the study of primate motor control, can be used as its own tachometer. This circuitry allows manipulanda using this type of motor to be made smaller, and with less moment of inertia, than would be possible with the installation of a separate ...

Automatic Torque Controller for Torque Motors

Journal of the Society of Motion Picture and Television Engineers, 1952
The use of the automatic torque controller permits the full advantages of torque motors to be realized for film take-up and holdback duty without being handicapped by their inherent limitations when operated in the conventional manner.

Single-Phase Motor-Torque Pulsations

Transactions of the American Institute of Electrical Engineers, 1924
This article gives results of a study of the vibrations of small single-phase induction motors, with a view to determining their causes and eliminating the noise which they produce. The possible sources of such vibrations were analyzed, and an experimental study was made in which the principal cause was definitely determined to be the double-frequency ...

Restoration of Torque in Defective Flagellar Motors

Science, 1988
Paralyzed motors of motA and motB point and deletion mutants of Escherichia coli were repaired by synthesis of wild-type protein. As found earlier with a point mutant of motB , torque was restored in a series of equally spaced steps. The size of
