Modal Analysis Of The Asynchronous Motor

International Journal of Modelling and Simulation, 1988
The availability or analytical expressions for the characteristic values of a generalized electrical machine model allows a deeper analysis to be carried out on the modes of the electrical dynamics...

Telemetry in diagnosis of asynchronous motors

2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG), 2015
To improve operational reliability of electrical machines over a long period of time, the diagnostic tests should be performed. This justifies the monitoring of machines, particularly those which do not have the reserve at the workplace: the power generators, hoisting machines in mines, etc.

The cascade synchronous–asynchronous motor

2019 International Conference on Electrotechnical Complexes and Systems (ICOECS), 2019
This 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

Asynchronous motors

2023
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, 2009
The 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), 1990
A 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.
