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

Telemetry in diagnosis of asynchronous motors
2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG), 2015To 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.

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.

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 ...
