Line start permanent magnet synchronous motors (LS-PMSM) are preferred more and more in industrial applications, because they can start on their own and because of their high efficiency. In this study, a new LS-PMSM rotor typology is suggested, which is modelled using surface mount permanent magnets, in which two different slot types have been used together. The rotor of an asynchronous motor on the industrial market in the IE2 efficiency segment has been remodeled in the study, resulting in an increase in motor efficiency from 85% to 91.8%. A finite elements software was used for determining motor design and performance, in addition to analytical methods.

Linear Synchronous Motors

<p>The permanent magnet linear motors are widely used in various industrial applications due to its advantages in comparisons with rotary motors such as mechanical durability and directly creating linear motions without gears or belts. The main difficulties of its control design are that the control performances include the tracking of position and velocity as well as guarantee limitations of the voltage control and its variation. In this work, a cascade control strategy including an inner and an outer loop is applied to synchronous linear motor. Particularly, an offline MPC controller based on MPP method and Laguerre model was proposed for inner loop and the outer controller was designed with the aid of nonlinear damping method. The numerical simulation was implemented to validate performance of the proposed controller under voltage input constraints.</p>

Hull Structure

An increasing number of Floating offshore units reach maturity (> 10 years). This induces costly maintenance operations related to hull structure corrosion damage. While crop and renew operations are generally performed in dry docks for supertankers, the FPSO are maintained afloat offshore on the oil field. For obvious security reasons hot work such as welding and gauging are prohibited without a heavy set of recommendations. Naturally, FPSO’s operators have sought “cold” solutions for decades. This paper describes the specificities of a particular structural bonded reinforcement (ColdShield developed by COLDPAD). A general description of its particularity in the fields of installation and durability is given, but this article is mainly focused on reinforcement strength criterion. Bonded reinforcement strength is known as difficult to predict, making design methodologies not compatible with industrial applications. The innovation in the design of the presented solution leads to a special behavior in terms of strength. It is revealed by the comparison of results of the qualification test campaign with results of tests realized on a standard bonded patch application. Finite element modelling computed parallelly to the tests are used to analyze the test results. The robustness of the reached strength criteria is discussed.

Magnetic springs are a fatigue-free alternative to mechanical springs that could enablecompliant actuation concepts in highly dynamic industrial applications. The goals of this article are:(1) to develop and validate a methodology for the optimal design of a magnetic spring and (2) tobenchmark the magnetic springs at the component level against conventional solutions, namely,mechanical springs and highly dynamic servo motors. We present an extensive exploration of themagnetic spring design space both with respect to topology and geometry sizing, using a 2D finiteelement magnetostatics software combined with a multi-objective genetic algorithm, as a part of aMagOpt design environment. The resulting Pareto-optima are used for benchmarking rotationalmagnetic springs back-to-back with classical industrial solutions. The design methodology has beenextensively validated using a combination of one physical prototype and multiple virtual designs.The findings show that magnetic springs possess an energy density 50% higher than that of stateof-the-art reported mechanical springs for the gigacycle regime and accordingly a torque densitysignificantly higher than that of state-of-the-practice permanently magnetic synchronous motors.

High Power Factor

Permanent magnet synchronous motors (PMSM) can be used directly in place of the induction motors (I.M) for several industrial applications since it is characterized by high efficiency, high power factor, and high power compared to I.M. However, this type of motor suffers from some abnormal conditions that result in minimizing power quality such as voltage sags, temporary disturbances, and faults within the network. In this paper, the behavior of PMSM has been studied under the above conditions in a Matlab/Simulink environment. It was noticed that such problems caused an increase in the amount of torque and current in this motor which impacted negatively on the motor speed and influenced the behavior of PMSM.

Approach Method

This paper suggests the use of the traditional proportional-integral-derivative (PID) controller to control the speed of multi Permanent Magnet Synchronous Motors (PMSMs). The PMSMs are commonly used in industrial applications due to their high steady state torque, high power, high efficiency, low inertia and simple control of their drives compared to the other motors drives. In the present study a mathematical model of three phase four poles PMSM is given and simulated. The closed loop speed control for this type of motors with voltage source inverter and abc to dq blocks are designed. The multi (Master/Slaves approach) method is proposed for PMSMs. Mathwork's Matlab/Simulink software package is selected to implement this model. The simulation results have illustrated that this control method can control the multi PMSMs successfully and give better performance.

Cationic Polyelectrolytes

AbstractCationic polyelectrolytes are water-soluble polymers bearing positive ionic groups along the backbone or in side chains. These cationic polymers are synthesized by free radical polymerization of acrylamide and their derivatives by the copolymerization method, which includes solution, precipitation, and emulsion techniques. The Mannich reaction is another important method by which the cationic polymers can be processed. In this review paper, the preparation methods, interaction mechanisms of these polymers, and their popular industrial applications are summarized. These polymers open a lot of applications in different fields such as paper-making processes, water and wastewater treatment, oil and drilling industries, mineral separation, paint and food industries, cosmetics, and pharmacy. In addition, these polymers are widely used as flocculants and rheology control agents. These polymers are especially employed in oil field operations as viscosity control agents for enhanced oil recovery, drilling fluid additives, and also for modifying flow and stability properties of aqueous solutions and gels. They are used as super-plasticizers, which affect the rheological properties of dense cement suspensions. Mining processes also benefit from the use of acrylamide derivative polymers to flocculate solids in aqueous dispersions. The cationic polymers may interact with different components in the system such as inorganic/organic particles in aqueous dispersions in several ways, which may result in the stability or instability of dispersion. The particles can be destabilized through three different main mechanisms which promote flocculation: polymer bridging, charge neutralization, and polymer adsorption.
