The asynchronous or induction motors work thanks to Faraday's law of induction (the induced electromotive force in a winding is proportional to the rate of change of its magnetic flux linkage) and Lenz's principle that the related induced current flowing in the winding produces a magnetic field which opposes the initial changing of the magnetic field ...

Energy-saving asynchronous motors
Russian Electrical Engineering, 2009The results of activities on creating asynchronous motors with rotor cast copper windings in Ukraine, the United States, France, Italy, Germany, Poland, Brazil, and India are analyzed. Tests have shown that motors have higher efficiency and higher useful power than analogs.

Asynchronous dielectric induction motor
IEE Proceedings A (Physical Science, Measurement and Instrumentation, Management and Education), 1990A small electrostatic induction motor has been constructed, consisting of a cylindrical stator with 24 bars, forming eight pitches of three bars each, adjacent bars being connected in sequence to the lines of a three-phase 50 Hz voltage supply of 1400 V/sub RMS/ line-to-line.

Prospects of constructing 20 kV asynchronous motors
IEEE Transactions on Dielectrics and Electrical Insulation, 200920 kV distribution networks with all its components, such as transformers, switches, cables etc., have existed and been operating safely for many decades. From an economic point of view, it would be convenient to replace the transformer-motor combination by just a single 20 kV asynchronous motor, even if the motor itself were more expensive.

Inverter-Fed Asynchronous Motors for Traction Systems
IFAC Proceedings Volumes, 1977Publisher Summary Variable-frequency inverter-fed asynchronous motor constitutes, in the field of electric traction, an effective option to traditional d.c. motor. The success of this equipment is connected to the advantages the squirrel cage asynchronous motor may provide lower weight and small dimensions, higher power at high speed, less ...

INCREMENTAL MOTION CONTROL SYSTEM WITH ASYNCHRONOUS MOTOR
IFAC Proceedings Volumes, 1983Abstract The possibilities of incremental motion control, with asynchronous motors are discussed. Various dc link static converters are shown, which provide the motor step by step operation, when the discrete information items into elementary displacements of the rotor are converted. An analytical expression of the electromagnetic torque developed by

Dynamic behavior of a multi-phase asynchronous motor
2009 European Control Conference (ECC), 2009The goal of this paper is the analysis of the dynamic behavior of a multi-phase asynchronous motor. The Power-Oriented Graphs technique has been used for modeling the system and a very simple and compact model has been obtained. The steady-state equations of the system have been studied finding remarkable relations between the motor voltage and current

Asynchronous performance of hysteresis motor
Journal of the Franklin Institute, 1975Abstract A simplified model of the hysteresis motor is introduced and analyzed; field analysis is undertaken at hand of Maxwell's stress tensor and Poynting's theorem. The suggested approach provides deeper insight into the power interchange process between stator and rotor.
