Mechanical characteristic of submersible asynchronous electric motor

Russian Electrical Engineering, 2010
More accurate torque-sleep formulas have been developed based on the equivalent circuit of a multicontour induction motor (IM). Methods of taking into account the saturation and skin effects on machine parameters are discussed. High-order and space harmonics and their dependences on the rotor speed are also included in the analysis.

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 ...
