Interior Permanent-Magnet Synchronous Motors Interior Permanent-Magnet Synchronous Motors Новинка

Interior Permanent-Magnet Synchronous Motors

Brushless permanent magnet (PM) motors can be divided into the PM synchronous AC motor (PMSM) and PM brushless DC motor (PMBDCM). The former has sinusoidal airgap flux and the back EMF, thus has to be supplied with sinusoidal current to produce constant torque. The PMBDCM has the trapezoidal back EMF, so the rectangular current waveform in its armature winding is required to obtain the low torque ripple. Generally, the magnets with parallel magnetization are used in the PMSM while the magnets with radial magnetization are suitable for the BDCM. The interior PM (IPM) synchronous machine is being studied as a promising candidate for high-power starter/alternator in future internal combustion engine vehicles. The other many popular applications of IPM machine are traction, machine tool, spindle drives, air conditioning compressors and electrical vehicles. Torque ripple minimization in PM motors is conventionally obtained by either good motor design or appropriate control strategies. In design optimization programs, a reliable and detailed analysis of the torque and back-EMF of the machine should be performed.

Open Bite Treatment With Magnetic And Spring Loaded Bite Blocks

Skeletal open bite malocclusion has long held great fascination in orthodontics. It is difficult to treat and relapse tendencies are strong. Successful stable results can be achieved when treated during the growth period. In non growing patients the opportunity for growth modification is lost, leaving surgical correction as the only possible treatment. This book discusses two innovative approaches by which excellent results can be achieved in difficult open bite cases during growing phase. Both approaches rely on use of modified bite blocks for control of vertical dimension. Active elements in the form of rare earth magnets and springs have been used to achieve effective molar intrusion and correction of open bite. Evaluation of treatment effects were done by EMG and cephalograms. Both the approaches provide exciting prospect for effective treatment of skeletal open bits malocclusion.

Wet-Chemistry: A Promising Route to Realize Exchange-Coupled Magnets

Magnets are inevitable from our lives. They are omnipresent in different forms in various appliances. Incessant research works are carried out in magnetic materials by researchers to enhance the performance of magnetic materials. Two systems viz. a soft Fe-Co and hard Sm-Co were selected and a few challenges were addressed in the syntheses and shape modifications which determines the magnetic properties of these materials. The effects of surfactant chemistry in modifying the morphology of Fe-Co nanoparticles from nucleated seeds to spheres, rectangular particles in three difference polyol processes and the reaction dynamics were discussed. Synthesis of Sm-Co nanoparticles through wet-chemical approach is a challenging task due to the mismatch oxidation potential of Sm and Co. The sample was prepared using sol-gel technique and effect of annealing temperature on structure, magnetic properties were described. These results will have significant importance in designing SmCo-FeCo nanocomposite exchange coupled spring coupled hard magnets.

Mad Science 2 Mad Science 2 Новинка

Mad Science 2

For nearly a decade Theodore Gray has been demonstrating the basic principles of Chemistry and physics through daredevil experiments that he executes, photographs and writes about for his monthly Popular Science column, Gray Matter. In the first collection of experiments, Theo Gray's Mad Science: Experiments You Can Do At Home, But Probably Shouldn't collected 54 experiements previously published in Popular Science, along with hundred of photographs, many of which were not published with the original columns. The experiments were organized into sections, from experiments that cause fiery explosions to those that use food or household products and more. Now comes the second volume of mad scientist experiments. Theo Gray's Mad Science 2raises the stakes with another 50, even more dramatic, daring and enlightening demonstrations in which Gray dips his hand into both molten lead and liquid nitrogen to demonstrate the Leindenfrost effect; crushes a tomato between two small magnets to demonstrate the power of neodymium-iron-boron magnets; shows the terrifying and deadly inferno that erupts when a frozen turkey is lowered into a deep fryer; and sculpts lovely trinkets out of solid mercury to demonstrate how the state of matter depends very much on the temperature at which it exists.

Small Electronically-Commutated Axial-Flux Permanent-Magnet Machines

The research work presented is about small electronically-commutated axial-flux permanent-magnet (AFPM) machines having the double-sided topology of an inner rotor with surface-mounted Nd-Fe-B magnets, sandwiched between two outer slotted stators with distributed three-phase windings. After reviewing the small double-sided AFPM machine candidate topologies for low-speed direct-drive applications, the book hinges on the size equations and the analytical electromagnetic design of the inner-rotor AFPM (AFIPM) machine topology under study. Original methods of modelling and design optimization of a small prototype AFIPM machine are then proposed with the view to reducing the airgap flux density space-harmonics and the torque ripple by rotor-PM shape modification. Extensive experimental tests are carried out on the small three-phase AFIPM machine prototype in order to validate its proper design and to check its electronic commutation and basic control technique.

Torque Ripple and Noise Control in Permanent Magnet Synchronous Motor Torque Ripple and Noise Control in Permanent Magnet Synchronous Motor Новинка

Torque Ripple and Noise Control in Permanent Magnet Synchronous Motor

This book investigates the minimization of torque ripples and harmonic noises in PMSM generated due to inverter switching system. In order to reduce torque ripples and harmonic noises in PMSM, three different methods have been proposed: a new dissipative passive filter topology to reduce torque ripples and harmonic noises in PMSM derived by FOC and HDTC algorithms have been proposed.In the second method an active filter topology have been proposed. The third method describes a new direct torque control algorithm for interior permanent magnet synchronous motor to improve the performance of hysteresis direct torque control (HDTC).The simulation results of this proposed algorithm show adequate dynamic torque performance and considerable torque ripples reduction as well as lower harmonic current and lower EMI noise level as compared to HDTC. These simulation resuls are supported by expeimental work

Tensor phase states in magnets with complex single-ion anisotropy Tensor phase states in magnets with complex single-ion anisotropy Новинка

Tensor phase states in magnets with complex single-ion anisotropy

Magnetic films are the subject of active researches because of their unique properties and various practical application. It is well known that the tensor of the magnetic anisotropy may have non-zero non-diagonal components. This may potentially lead to the realization of complex magnetic structures with non-trivial distribution of the magnetization. This book is an attempt to summarize the results of theoretical investigations of the systems with inclined single-ion anisotropy. We describe the results obtained during the researches of the phase states and of the elementary excitations in the two-dimensional systems with strong single-ion anisotropy. These results become especially interesting with the account of the wide practical application of the systems with the inclined single-ion anisotropy.

Construction of Horizontal Axis Wind Turbines A beginners Approach

The most important component of a Wind Energy Converter is the rotor. The efficiency of a rotor is characterized by its profile (airfoil section) and the corresponding aerodynamic design. The NACA 4415 is selected as an aerofoil for the rotor due to its increased efficiency. A light with a good strength is used for the blades. The blade is carved at different blade angles.Alternator is made of two components, magnet rotor and stator. Magnet rotor is mild steel disk with magnets positioned on it using molding process. Stator is made of 9 coils. Each coil with 220 turns number of turns. The stator is sandwiched between the magnet rotors. With the rotary motion of magnet rotors, flux is generated and hence AC voltage is in the coil which is converted into DC voltage with the help of bridge rectifiers. The output in the form of DC volt is used to charge the battery. The furling system is used for rotating the turbine to the desired direction of the wind.
