Identification and diagnosis of electrical fault of asynchronous motor

2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010
this paper puts forward the method that the wavelet combines with neural network, and applies the method to identify and diagnose the electrical fault of small asynchronous motor. By experiment we can obtain the data when the small asynchronous motor exist the air gap eccentricity and turn-to-turn short circuit fault and then picks up the two fault ...

Mathematical modeling of damage in an asynchronous electric motor

Safety and Reliability of Power Industry
The paper presents brief statistics on damage to asynchronous electric motors, which serve as drives for the main equipment of metallurgical industry enterprises and for the auxiliary systems of electric power plants. It is noted that the most frequent faults include damage to the bearing unit, stator windings and rotor bars.

Load balancing of two-motor asynchronous electric drive

2015 International Siberian Conference on Control and Communications (SIBCON), 2015
Multi-motor electric drives are widely used in many industries due to increased reliability, weight and size, and other parameters. One of the drawbacks of multi-motor electric drives is non-uniform load distribution. The reason lies in disorder in parameters of the motors of the same catalog data.

OPTIMAL CONTROL OF ASYNCHRONOUS ELECTRIC MOTOR WITH VARYING FREQUENCY

Electric Machines & Power Systems, 1996
The control of the asynchronous motor speed in a wide range is based on frequency control, i.e. on the variation of the frequency and voltage amplitude applied to the stator according to a special law. The progress of microcomputers gives new opportunities to frequency control design.
