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.

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 ...

Asynchronous motor drive loss optimization
Journal of Materials Processing Technology, 2007Abstract This paper presents a methodology for determination of harmonic iron losses in laminated iron cores under non sinusoidal excitation. The methodology adopted is based on a particular 3D finite element model by using a reduced scalar potential formulation.

The cascade synchronous–asynchronous motor
2019 International Conference on Electrotechnical Complexes and Systems (ICOECS), 2019This paper describes the mechanism and the principle of operation of a cascade asynchronous-synchronous motor. The history of their creation, and the main advantages are given. The analysis of operation of the cascade system under load is carried out, the scheme of substitution is given. It is determined that when the motor is under load the lag in the

Reluctance synchronous motor asynchronous operation
IEEE CCECE2002. Canadian Conference on Electrical and Computer Engineering. Conference Proceedings (Cat. No.02CH37373), 2003Although a synchronous machine is under consideration in this paper, the asynchronous performance of the reluctance synchronous machine is the relevant consideration. The machine starting procedure and its ability to synchronize successfully, even with high inertia loads, are also important issues to be considered in this paper.

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

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.
