dc machinescascade substitution schemeanisotron modelFlat and cylindrical layered models of electric machines have proven themselves well in electromagnetic calculations. In such models the general solutions of partial differential equations are transformed into a system of four-pole equations, which makes ...

An equivalent-circuit model of a linear induction motor is developed, using the rotary-motor model as a basis. The rotary-motor model is modified to account for the so-called `end effect and is used to predict output thrust, vertical forces and couples. These predictions are checked against ...
Electric Submersible Pump (ESP), as a kind of mechanical oil recovery equipment, has been widely used in recent years. This paper investigates an equivalent circuit of ESP system that can be proposed to extract the motor stator voltage, the differential mode voltage between the filter, cable, ...
Although the resistance in both directions was tested, the polarization of the concrete could not be eliminated. Therefore, a resistor box with a large resistance is connected in series to the circuit, thereby preventing the measurement of a negative resistance value by the intelligent resistivity ...
How do you calculate the RMS value for a square wave with peak-to-peak voltage of 4V and a 2V DC offset? Distinguish between the peak voltage and the rms voltage. The rms output in a circuit is 7.75 A. What is the maximum current? A generator's maximum is 220 V. What is the ...
Moreover, output characteristics for variable resistive load and the operating speed are also obtained by solving the permanent magnet machine's equivalent circuit equation. The analytical results are validated extensively by nonlinear finite element analysis and experimental results. 展开 ...
The circuit consists of a switching-mode servo loop in which U1a generates a triangular waveform of approximately 20-mV amplitude. U1b acts as a buffer with C2 and R4 removing any residual dc offset. The signal is then applied to the inverting input of the comparator under test, while the ...
