T-Rex Speaks: http://www.energeticforum.com/90090-post71.html at 03-27-2010, 03:23 PM There are some very serious misconceptions in the world of Electrical Engineering today. (The writings of Oliver Heaviside and Proteus Steinmetz gravely warned about this...) Let us start with the YouTube MIT Physics Demo video that Armagdn03 posted a link to on 11-10-2009 on page 2 of this thread. Note: This one: This is a good demonstration for several reasons. 1.) Glass is a dielectric which can store electrical energy within its physical form. This should be common knowledge and not a surprise to anyone today… 2.) That this simple fact and reality “blows some people’s minds” clearly illustrates that it’s just all gone way, way, too far… The Einsteinian Lie has succeeded in instilling a mind virus in most everyone and also in confusing Main Stream “Scientists”, who today waste billions of dollars of funding each year, only to chase their own tails in a canonic sequence. 1 of 49 29-10-11 20:16 Tuks DrippingPedia : Energetic Form Posts http://www.tuks.nl/wiki/index.php/Main/Energetic...

Understanding Permanent Magnet Motor Operation and Optimized Filter Solutions
Understanding Permanent Magnet Motor Operation and Optimized Filter Solutions June 15, 2016 Todd Shudarek, Principal Engineer MTE Corporation N83 W13330 Leon Road Menomonee Falls WI 53154 www.mtecorp.com Abstract Recent trends indicate the use of permanent magnet (PM) motors because of its energy savings over induction motors. PM motors offer energy savings, higher power densities, and improved control. The upfront cost of a PM motor may be higher than an induction motor, but the total cost of ownership may be lower. However, a PM motor system brings design challenges in terms of selecting the best variable frequency drive (VFD) as well as a filter to protect the motor. A PM motor requires the use of a VFD to start and operate. The best VFDs will need to operate at higher switching frequencies to meet the higher fundamental frequencies of the PM motors. In turn, the PM motor will need to be protected from power distortion, harmonics, and overheating. While a traditional filter is de-rated to meet the higher frequencies, this paper will demonstrate that, by nature of the operation of a PM motor, an appropriately design filter that operates for higher switching and fundamental frequencies will reduce the size, weight, and cost of the system. Introduction special considerations when specifying a filter for a PM motor system, specifically the use of Historically induction motors have been used in higher switching frequencies and filters. a variety of industrial applications. Recent trends indicate a shift toward permanent magnet (PM) motors which offer up to 20% energy savings, Induction Motor Operation higher power densities, and improved control. -
Axial Field Permanent Magnet Machines with High Overload Capability for Transient Actuation Applications
THE UNIVERSITY OF SHEFFIELD Axial field permanent magnet machines with high overload capability for transient actuation applications By Jiangnan Gong A Thesis submitted for the degree of Doctor of Philosophy Department of Electronic and Electrical Engineering The University of Sheffield. JANUARY 2018 ABSTRACT This thesis describes the design, construction and testing of an axial field permanent magnet machine for an aero-engine variable guide vane actuation system. The electrical machine is used in combination with a leadscrew unit that results in a minimum torque specification of 50Nm up to a maximum speed of 500rpm. The combination of the geometry of the space envelope available and the modest maximum speed lends itself to the consideration of an axial field permanent magnet machines. The relative merits of three topologies of double-sided permanent magnet axial field machines are discussed, viz. a slotless toroidal wound machine, a slotted toroidal machine and a yokeless axial field machine with separate tooth modules. Representative designs are established and analysed with three-dimensional finite element method, each of these 3 topologies are established on the basis of a transient winding current density of 30A/mm2. Having established three designs and compared their performance at the rated 50Nm point, further overload capability is compared in which the merits of the slotless machine is illustrated. Specifically, this type of axial field machine retains a linear torque versus current characteristic up to higher torques than the other two topologies, which are increasingly affected by magnetic saturation. Having selected a slotless machine as the preferred design, further design optimization was performed, including detailed assessment of transient performance. -

The penalty is the increase in demand for electrical power. It is estimated that the steady state power requirement in the typical luxury class vehicle would rise from the current level of 1500 W to about 3000 W and to about 7000 W for a hybrid electric vehicle by the year 2005 [16,17,2]. -

A permanent magnetic linear oscillating synchronous motor (PMLOSM) provides reciprocating motion which can drive a piston pump directly having advantages of high frequency, high reliability, and easy commercial manufacture. Hence, researching the tracking perfor- mance of PMLOSM is of great importance to realizing its popularization and application. Traditional PI control cannot fulfill the requirement of high tracking precision, and PMLOSM performance has high phase lag because of high control stiffness. In this paper, an advancing motivation feedforward control (AMFC), which is a combination of advancing motivation signal and PI control signal, is proposed to obtain high tracking precision of PMLOSM. The PMLOSM inserted with AMFC can provide accurate trajectory tracking at a high frequency. Compared with single PI control, AMFC can reduce the phase lag from −18 to −2.7 degrees, which shows great promotion of the tracking Citation: Jiao, Z.; Cao, Y.; Yan, L.; Li, precision of PMLOSM. -

This study analyzed the rotor shapes of IPM motors for electric vehicles. Five types of motor rotors for automobiles were analyzed, including two hybrid vehicles. In order to minimize the number of variables in the analysis, the size of the motor stators was fixed and only the rotor shapes were modified to compare torque, torque ripple, efficiency and back-electromotive voltage. When the motor properties were compared as a function of rotor shape, the rotor shape with the smallest magnet volume exhibited excellent results for torque, efficiency and torque ripple. Keywords: traction motor; electric vehicle; interior permanent magnet; vehicle motor; electromagnetic field analysis; cogging torque 1. Introduction Various regulations in the car industry are being introduced to respond to environmental changes caused by global warming [1]; for example, electrically powered powertrains have been developed to reduce exhausted gas and improve the power efficiency of vehicles. -

Rajkumar** *(Department of Mechanical Engineering, Chandy College of Engineering, Affliated to Anna University- Chennai, Tuticorin-05) ** (Department of Mechanical Engineering, Chandy College of Engineering,Affliated to Anna University- Chennai, Tuticorin-05) ABSTRACT This project is based on the need for the unconventional motor. This work will be another addition in the unconventional revolution. Our project is mainly composed of design and fabrication of the ―MOTO AUTOR‖ which is a replacement of conventional motors in many applications of it. This motoautor can run on its own without any traditional input for fuelling it except for the initiation where permanent magnets has to be installed at first. It is a perpetual motion system that can energize itself by taking up the free energy present in the nature itself. This project enables to motorize systems with very minimal expenditure of energy.
