Ambient Signals based Load Modeling with Two Three-phase Induction Motors

Abstract The traditional electric power system simulation and calculation are based on the simple load model including one motor and one static load. On the one hand, the power system load is getting more and more complex. On the other hand, it’s proved that two kinds of three-phase induction motors will show a little difference. As a result, in this paper, a new model load with two three-phase induction motors is proposed. Besides, the dynamic of the power system load is taken into account. The torque of those two three-phase motors will show different characteristics, that one is constant and the other is variable. Formerly, the dynamic of the load is regarded as the result of an induction motor. However, the single-phase motor and electronic load both lead to the complexity of the load. To get a more accurate calculation, we need a more proper load model. One of the ways to improve the load model is to pay more attention to the ingredients ignored. The single-phase motor and power electronic load make a great difference. Besides, it’s proved that the composited load model with two three-phase motors will be better in the calculation.

A Noval Method of Single Phase to Three Phase Cyclo Converter for Three Phase Induction Motor Drive

This paper present the study on analysis of speed of induction motor when the motor is made to run on different loads torque. fed by single phase to three phase cyclo converter.. Normally, constant voltage constant frequency single phase AC or three phase AC is used. However in some rural areas, only a single phase utility is available, so it became necessary to convert single phase supply to three phase supply to run three phase induction motors. For this purpose, cyclo converter model is patterned by MATLAB/SIMULINK SOFTWARE to convert single phase supply to three phase supply. Converter model employs only six IGBT so the resulting Cyclo converter-motor drive system is cheap and compact, As we know that the rating of the machine increases with the increase in number of phase .eg. output of three phase motor is 1.5 times the output of a single phase motor of same size. therefore it is beneficial to use three phase induction motor instead of single phase induction motor for low industrial applications

Hoods are the most important devices used in our kitchens that contribute to the ventilation of the environment. 95% of the electric motors used in hoods are single-phase asynchronous motors. There are many domestic and foreign electric motor manufacturers producing for the hood industry. Supplier selection in companies producing hoods is vital and critical for sustainable production. It is extremely important to make the right decision in the purchasing process of the supplied products. While the decisions taken can sometimes be clearly separated from each other, sometimes they can be intertwined and interconnected. Multi criteria decision making techniques are used when making decisions that cannot be clearly separated or explained with numerical data. The aim of this study was to determine the most suitable Supplier for the built-in appliance company operating in the Turkiye/Amasya region by using fuzzyTOPSIS method in the supply of 1-phase asynchronous motors used in hoods.

The best supplier selection among 6 different suppliers was made using this method. For the first time, a solution proposal was presented with the fuzzyTOPSIS technique for the 1-phase induction motor supplier selection and a contribution was made to the literature.

A Study on Eddy Current Reduction Shape of Single-Phase Claw-Pole Motor

The claw-pole motor, known for its simple structure, is widely used in various fields due to its cost competitiveness. However, a drawback of the fixed-stator-type claw-pole motor is its vulnerability to eddy current losses. Therefore, this paper presents a single-phase claw-pole motor applied as a motor for cooling fans, with the aim of reducing eddy current losses and improving performance based on shape optimization, ultimately resulting in a single-phase claw-pole motor that meets the desired performance. The validity of this approach is verified through 3D finite element analysis (FEA).

Control Method of Electrolytic Capacitor-Less Dual Inverter-Fed IPMSM under Periodic Load Torque Fluctuations

This paper proposes a control method for an electrolytic capacitor-less dual inverter for compressors. Single-phase motor drive systems are required to minimize vibrations, maintain a high power factor, and meet the limit for harmonic current emissions. The proposed control method achieves the harmonic reduction of the dq-axis currents, a high power factor, and a low grid current THD under periodic load torque fluctuations. The effectiveness of the proposed method is demonstrated via experimental results, using an open-end winding IPMSM and an electrolytic capacitor-less dual inverter. The proposed method reduced the 100Hz harmonic components of dq-axis currents up to 98% under periodic load torque fluctuations compared with an electrolytic capacitor-less single inverter. The results of FFT analysis of the input current show that the power factor and input current THD of the proposed method are equivalent to or superior to those of conventional methods. Therefore, the proposed control method can effectively achieve vibration reduction, a high power factor, and a reduction in the input current THD under periodic load torque fluctuations.

Analysis and comparison of single-phase induction motor operation from single- and two-phase power sources using MATLAB simulation results

<span lang="EN-US">Single phase induction motor (SPIM) has zero torque, this motor has many types and the main objective is to find the starting torque of the motor. This is done by providing auxiliary coils that are mechanically separated or weakened after 75% of the engine speed. The real problem here is that these auxiliary windings occupy a third of the iron core of the motor, and when they are separated or weakened, the capacity of the iron core is not fully used and the main windings must withstand the rated load current alone which shortens the life of the motor and reduces the hours of continuous operation of the motor. In this paper, a single-phase motor is fed from a single-phase power source and again from a two-phase power source, so that the auxiliary coils are not separated after 75% of the motor's speed and have a continuous role in the motor's operation. The torque and current flow in the motor are compared in both cases. Due to the rarity of the two-phase power supply in nominal uses, it can be supplied by a full bridge inverter. This comparison was provided by steady-state analysis and the results of MATLAB Simulink. </span>

Design of High-efficiency Single-phase Direct-on-line Synchronous Reluctance Motors for Pump Applications

With high surrounding temperatures, winding resistance increases and thus lowers the operational efficiency of a motor. To meet the large application requirements and conform with the ever-increasing energy-efficiency regulations for pump equipment in the metals industry, consistent efforts have focused on producing single-phase motors that can deliver superior performance at a low cost. Because the steady-state rotational speed is synchronized and no driver circuit is required, a direct-on-line synchronous reluctance motor is a potentially viable alternative to the commonly adopted induction motors. Its inherently simple structure and comparably low operational speed necessitate a challenging structural design for accomplishing the high-efficiency objectives of pump applications. These challenges and their potential solutions are reported in detail. By employing a systematic design scheme and including thermal concerns of the performance, a competitive high-efficiency single-phase direct-on-line synchronous reluctance motor for pump applications in various metal industry equipment was offered.

Discrete Design Optimization Of A 3-Phase Squirrel Cage Type Induction Motor

The broad application of modern industrial drives is implemented as a three-phase squirrelcage type induction motor. The outpaced their predecessor the D.C motors for various advantages they have. Slip-ring or phase-wound types are used as adjustable-speed drives. Later arrival of power-electronic equipment’s cage-type motors are additionally being utilized as customizable speed drives. The single-phase motors are also widely used for running small machineries and domestic appliances. The total expenses for these motors constitute the largest fraction of the total investment at the consumer end. Therefore, they must be developed cost-optimally. At the same time, they must correspond to the criteria defined by the client or the legislative requirements enforced by the authorities. If the design is produced according to recommendations offered in the text-books, we may expect to get merely a workable solution but not the costoptimum solution. For job work, it is cheap to utilize standard stampings since this approach avoids the cost of dies which is rather expensive. The paper presents an iterative procedure to get the cost-optimal solution subject to usual design constraints, using standard stampings available in the market. A case study has been made on its basis and optimal design approach saves money.

DESIGN AND DEVELOPMENT OF GROUNDNUT POD SEPARATOR MACHINE

Agriculture is the backbone of India. In country like India, the yield of groundnuts is very low. The serious issue in groundnut production in India is the absence of groundnut handling machines accessible or the machines which are accessible in market are expensive to farmers. Before all else, the pods of groundnut were isolated from its plants by workers. They just eliminate groundnut pods with the assistance of their hands and separate them from the plants. The yield got from this strategy, was exceptionally low since it was an extremely tedious process. It was additionally a disappointing work for the workers. The customary strategy for isolating groundnut pods from plants is by hands. That conventional strategy is anything but an adequate technique for isolating groundnut pods. To conquer this manual tedious and disappointed interaction MGIRI's REI (Rural Energy and Infrastructure Department) has created single phase electrically worked "Groundnut Pod Separating machine" The machine has the capacity of isolating 400 kg of groundnut each hour with isolating efficiencies of 90% and 95%. The machine is created from locally sourced materials, which makes it exceptionally modest and effectively reasonable and furthermore, an upkeep cost of the machine is extremely low. It comprises of two turning rotors, 1HP single phase motor and separator to remove soil and gather the groundnuts.

Three-Coil Combined Winding Configuration for a 2-DOF Actively Controlled Bearingless Permanent Magnet Motor

This study describes a simple combined winding configuration for a two-degrees-of-freedom (DOF) controlled bearingless motor with a six-slot/six-pole permanent magnet (PM) structure. This bearingless PM motor has only three concentrated coils that are wound alternately on six teeth of the stator and employs only one three-phase inverter for both the two-DOF radial magnetic suspension and single-phase motor drive. Theoretical calculation and finite element method (FEM) analysis demonstrated that the proposed three-coil combined winding configuration generates a four-pole rotating field and six-pole alternating field for generating radial suspension force and torque, respectively. To verify the proposed configuration, we built and tested an outer rotor bearingless PM motor with a diameter of 58 mm and a height of 5 mm. The rotor was successfully levitated and driven up to 7500 rpm. The calculated and measured results were compared for both the proposed combined winding configuration and the previously developed separated winding configuration. The measured motor efficiency of the prototype with the combined winding at 5000 rpm with 20 mNm output is improved by 5% due to the copper loss reduction when compared to that with the separated winding.

FINITE ELEMENT ANALYSIS OF SHADED POLE MOTOR BASED ON MAXWELL2D

Shaded pole induction motor is one of the simplest and least expensive types of single-phase motors, but one of the most difficult to analyze. In this paper, we adopted a two-dimensional finite element method 2DFEM, which is one of the most accurate methods to analyze such motors. We used Ansys Maxwell2D software with assist of AutoCAD software in modeling and analyzing a reluctance-augmented shaded pole motor. The 2DFEM results of torques and currents for this motor obtained from Maxwell2D were compared with the analytical results and appeared a good agreement.

Noise Reduction Design with Trapezoidal Back-EMF and Asymmetric Air-Gap for Single-Phase BLDC Refrigerator Cooling Fan Motor

In this study, a novel method for reducing the noise generated by single-phase claw-pole motors employed as refrigerator fan blowers is proposed. A single-phase claw-pole motor has the advantages of low manufacturing cost, easy manufacturing, and a high number of turns. However, in such motors, current delays occur owing to a high inductance; therefore, it is necessary to merge the back-electromotive force and current phases into the same phase using the phase advance method. Additionally, a single-phase motor exhibits dead torque and zero torque at an electrical angle of 180° owing to its electrical characteristics, and the dead torque deteriorates the average torque and torque ripple characteristics of the motor. In this study, a novel method is proposed to make the air gap asymmetrical by tilting the claw to reduce the noise generated by single-phase claw-pole motors. An asymmetric air gap allows the cogging torque to eliminate the dead torque caused by alignment torques, causing the torque ripple to decrease. To validate the effectiveness of the proposed method, the proposed model is compared with a base model via three-dimensional finite element analysis. Furthermore, the two models are manufactured and a noise test is conducted in an anechoic chamber to compare the noise difference between the two models.
