Применение вращающейся системы отсчета к теории асинхронного двигателя

Described an efficient method of calculating the parameters of the electric motor with a rotating frame of reference. Described expressions to determine the induction of EMF in the phase stator windings and provided a frame of reference and the location of the motor rotor bars. For research and calculation of electrical processes in the rotor induction motor was presented rotating coordinate system and derived mathematical relationships for induction emf conductive rods moving rotor below the upper band division, taking into account the shift of the initial phases. Also compiled a simplified equivalent circuit diagram for the determination of the currents flowing in the conductive rods that define the power characteristics of the motor. To calculate the currents in the equivalent circuit diagram used method of applying. For this series of induction EMF is divided into complex impedance conductive rods and received currents shifted in phase due to the angles and the additional shift due to the complex impedance. It is shown that the use of this technique reduces the amount of computations and simplifies the interpretation of results.
