4 Date of Submission: 20th March‚ 2013 1. The rotor shown in Fig.1 has two coils. The rotor is nonmagnetic and and is placed in a uniform magnetic field of magnitude B0 . The coil sides are of radius R and are uniformly spaced around the rotor surface. The first coil carrying a current I1 and second coil carrying a current I2 . Assuming that the rotor is 0.30 m long‚ R=0.13 m‚ and B0 = 0.85 T‚ find the Θ directed torque as a function of rotor position α for (a) I1 =0A and I2 =5A‚ (b)I1 =5A and

HISTROY The evolution of active magnetic bearings may be traced through the patent issued in this field. Earlier patents for magnetic suspensions can be found but are excluded here because they consist of assemblies of permanent magnets of problematic stability per Earns haw’s Theorem. Early active magnetic bearing patents were assigned to Jesse beams at the university of Virginia during World War II and are concerned with ultracentrifuges for purification of the isotopes of various elements for

Wind Energy A turbine is machine that spins arounds catching energy that’s passing by. The huge rotor blades (propellers) on the front of a wind turbine are the "turbine" part. As wind passes by‚ the kinetic energy (energy of movement) it contains makes the blades spin around (usually quite slowly). The blades have a special curved shape so they capture as much energy from the wind as possible. Although we talk about "wind turbines‚" the turbine is only one of the three main

reactive power with the grid. Running on different operating conditions‚ the rotor of DFIG has different energy flow directions. Although energy always flows from stator to grid‚ sub-synchronous operating state‚ the energy flows from the grid to the rotor; super-synchronous operating state‚ the energy flows in an opposite way. Therefore‚ in order to make the system run in a wide speed range‚ it has to ensure that the rotor energy can flow in double-way. This process is achieved with GSC by regulating

DESIGN OF TESLA TURBINE Abstract:- The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The Tesla turbine is also known as the boundary layer turbine‚ cohesion-type turbine‚ and Prandtl layer turbine (after Ludwig Prandtl). Bioengineering researchers have referred
