“…Field analysis were carried out in the ANSYS Maxwell 2D and 3D simulation software for a 16-kVA salient pole synchronous generator. The generator model [24] was created according to the geometric dimensions and electrical data contained in Table 4 and is presented in Figure 5. The created three-dimensional field model of the machine contained 331,743 mesh elements.…”

This paper presents an analysis of the short-circuit currents of a synchronous generator with a rated power of 16 kVA. For this purpose, the authors carried out measurements of real short-circuit currents during laboratory tests. Additionally, a simulation model of the generator was developed according to the individual machines data from the catalog and field calculations in ANSYS Maxwell software. Based on the mentioned research, the authors compared waveforms of the symmetrical short-circuit currents. In this paper, the last compared family of short-circuit current waveforms was obtained using analytic calculations. As the presented comparison shows, the assumed method of selecting short-circuit waveforms impacted their values. However, the difference in energy related to short-circuit currents did not influence on the selection of the short-circuit protections, especially at low values of steady-state short-circuit currents and short time constants characteristic for the generators, performing the functions of an alternative power supply. Regardless of the research method, the results presented in the article show that the selection of the short-circuit protections is complicated in case of hybrid electrical systems equipped with low power generators.

“…The most popular scalar control techniques, known as constant V/Hz (or constant V/F), is the simplest means to achieve linear control of IM's torque and speed [20,21]. This control mechanism ensures the operation of the IM at its rated flux, thus prevents the rotor core magnetization reaching its saturation and run in its hysteresis loop.…”

An induction motor (IM) has been the workhorse of the industry for decades. It is due to its robustness, simple construction, requiring less maintenance and cheap. One of the most widely adopted IM drive control schemes for industrial applications is the open-loop constant V/Hz. In this paper, the important elements of an open-loop constant V/Hz drives are presented. These include the fundamental concept of a constant V/Hz scheme, the voltage source inverter (VSI) and its modulation schemes. Techniques that are commonly used to solve problems of low-speed operation and rotor speed regulation are briefly described. Simulations using MATLAB/Simulink package are used to help in illustrating these fundamental concepts. Finally, simple laboratory-scale experiments are conducted to implement the constant V/Hz control scheme on a ¼ hp induction motor. The constant V/Hz control is implemented using the DS1104 controller board with the C codes automatically generated from the Simulink model. A closer look at the current waveform when fref=25 Hz and 12 Hz and its respective Fourier analysis are presented. The results show that the high-frequency harmonic contents around the switching frequency can be observed for both cases, and the voltage waveform presents more spike noises in constrast to current waveform.

“…Finite element analysis aims to calculate characteristics of servomotor, such as density of flux, inductance, torque, etc, that allows to verify the optimal design of asynchronous servomotor obtained in [13]. In FEA, the magnetic circuit is modelled by a mesh of elements [16]. The values are then assumed to be magnetic functions of positioning within these elements, allowing the results to be interpolated.…”

This paper proposes an optimal design “modern” approach for servomotors. This approach consists of the optimization algorithms at the initial analytical calculations and the modelling of the virtual prototype in order to reduce the costly and time-consuming prototyping loops of the “conventional” design method. The optimal design of a servomotor for robot application is verified by using finite element analysis (FEA) in terms of torque at low to high speeds. The thermal simulations based on lumped-mass model have been conducted in order to determine the operating duration of maximum and continuous performances of this machine. A prototype of asynchronous servomotor is manufactured and tested in the test-bench. Experimental results of electromagnetic (torque) and thermal (rising temperatures of different positions in the motor) measurements of peak and continuous performances at different speeds will validate the virtual prototype as well as this design method.
