ASYNCHRONOUS ELECTRIC MOTOR WITH SINGLE-PHASE STATOR WINDING

Automation of technological and business processes, 2023
The current standard considers the efficiency of electric motors only in terms of power efficiency and does not pay attention to the so-called economic efficiency - the power factor that affects the loss of electricity in the motor supply network and depends on its energy excellence.This ill-considered approach to establishing the energy efficiency ...

Finite element modeling of asynchronous electric motors with electrical defects of stator and rotor

Journal of Physics: Conference Series, 2020
Abstract The paper presents results of finite element modeling of induction motor in the growth of stator and rotor fault. Due to the symmetry design of the electric motors relative to the rotor axis the simulation problem is solved in a plane orthogonal axicon. Obtained data the characteristics variation of induction motors with defects:

Computational analysis of the temperature improvement of electric asynchronal motors

The Journal of Zhytomyr State Technological University. Series: Engineering, 2019
In the development of electric machines as a whole, as well as asynchronous motors, in particular, the limit values of temperature are the key factors that affect the efficiency of the overall design. Since the usual load of asynchronous motors often occurs, hence, the estimation of temperature rise with the help of mathematical modeling tools and ...
